Overview and Layout
1336 REGEN Line Regeneration Package
The 1336 REGEN Line Regeneration Package is a line regenerative option for
drives in the 1336 drive family. Line regeneration refers to the removal of energy
from the common DC bus of one or more AC drives, back onto the three-phase
AC utility line.
The 1336 REGEN Line Regeneration Package operates in two basic modes:
Regenerative DC Bus Supply, and Regenerative Braking. These two operating
modes give the 1336 REGEN Line Regeneration Package the flexibility to handle
a wide variety of applications.
1336 REGEN Line Regeneration Package Components
The 1336 REGEN Line Regeneration Package consists of two main pieces:
• A Converter that transforms a three-phase AC input source into a DC
output source.
• A Precharge Unit that limits inrush current and provides AC line voltage
phase and magnitude information to the converter.
In addition to these two components, a 1321 Line Reactor is required. The line
reactor used for Regenerative Bus Supply applications is a custom design with a
nominal impedance of 10%. Operation in the Regenerative DC Bus Supply
Mode may also require the use of an additional power line filter, depending upon
the AC line source impedance. Operation in the Regenerative Brake Mode
requires the use of a line reactor with a nominal impedance of 3%. Figure 1 and
Figure 2 show the basic layout differences between the1336 REGEN
Regenerative DC Bus Supply, and the 1336 REGEN Regenerative Brake
applications, respectively.
How to Choose a Mode of Operation
Several characteristics influence the choice of an operating mode for a given
application. The 1336 REGEN Line Regeneration Package can be used with any
380...480 volt drive in the 1336 family. The desired performance of the combined
AC drive/Line Regeneration Package dictates which mode of operation is best
for an application. The choice of operating mode also affects the cost of
implementation, since hardware requirements are different for the two modes of
operation. The following discussion describes these two modes in detail and
points you to the best operating mode for several common applications.

Chapter 1
Comparison and Selection
The Regenerative DC Bus Supply Mode
In the Regenerative DC Bus Supply Mode, the 1336 REGEN Line Regeneration
Package supplies both motoring and regenerative current to one or more
common bus drives.
IMPORTANT
A common bus drive is not a standard AC-input AC drive. Throughout this
manual a common bus drive is defined as a 1336 family AC drive
designed to be powered by a DC power source connected to a common
DC bus.
When the net power requirement of the attached common bus drives demand
motoring power, energy flows from the utility to the common DC bus.
When the net power requirement of the attached common bus drives demand
regenerative power, energy flows from the common DC bus to the utility.
• Precharge for all common bus drives on the common DC bus is
accomplished through the 1336 REGEN Line Regeneration Package. As a
result, three-phase AC power is not connected to the individual drives.
However, individual common bus drives do have separate precharge
circuits, to allow them to be connected to the powered DC bus.
• Since the 1336 REGEN Line Regeneration Package supplies both
motoring and regenerative current to the drives, the precharge, converter,
and line reactor must all be sized to handle the peak power requirements of
the connected common bus drives in any quadrant of drive operation.
• In the Regenerative DC Bus Supply Mode, the 1336 REGEN Converter
operates as a Pulse Width Modulation (PWM) converter, creating
sinusoidal input AC line currents under both motoring and regenerating
conditions. Operation in this mode results in the additional benefit of very
low harmonic current distortion that typically meets Institute of Electrical
and Electronics Engineers (IEEE) 519-1992 specifications.
IMPORTANT
Refer to Chapter 2 of the 1336 REGEN Line Regeneration Package User
Manual, publication 1336 REGEN-5.0, for 1336 REGEN Regenerative DC
Bus Supply applications including Installation, Setup, and Programming
information.
The Regenerative Brake Mode
In the Regenerative Brake Mode, the 1336 REGEN Line Regeneration Package
removes energy from the DC bus of a standard 1336 AC drive back to the utility.
• When the connected AC drive is motoring, it receives energy directly from
the three-phase AC line through its input terminals and Diode Bridge.
• When the connected AC drive is regenerating, energy flows from the DC
bus back to the three-phase utility through the 1336 REGEN Line
Regeneration Package.

Rockwell Automation Publication 1336R-AP001A-EN-P - July 2011
Comparison and Selection
Chapter 1
Precharge of the DC bus is accomplished simultaneously through the
1336 REGEN Precharge Unit and the precharge circuit of the 1336 AC drive. In
the Regenerative Brake Mode, the 1336 REGEN Line Regeneration Package is
not required to supply motoring current to the AC drive. Because of this, the
1336 REGEN Line Regeneration Package can be sized to provide whatever
braking capability is needed by the application, independent of the total
horsepower (HP) needed for motoring.
In the Regenerative Brake Mode, the 1336 REGEN Line Regeneration Package
switches synchronously with the AC line voltage, but does not attempt to create
sinusoidal input AC line currents with a PWM scheme. The resulting power
factor is near unity. The AC line current harmonic spectrum resulting from the
combination of an AC drive and a 1336 REGEN Line Regeneration Package
operating in the Regenerative Brake Mode is nearly equal to that of a standard
1336 AC drive that is motoring.
IMPORTANT
Refer to Chapter 3 of the 1336 REGEN Line Regeneration Package User
Manual, publication 1336 REGEN-5.0, for 1336 REGEN Regeneration
Brake applications including Installation, Setup, and Programming
information.

❶ The Regenerative Bus Supply Mode can also be used for these applications, but
will result in a more complex hardware configuration and a higher total system
cost. Regenerative Bus Supply operation requires a custom Bulletin 1321 10%
line reactor, while Regenerative Brake operation requires a standard Bulletin
1321 3% line reactor. The mode of operation is selected by a parameter setting for
parameter 1 [Operational Mode] in the 1336 REGEN Converter. Refer to the
Programming sections in Chapters 2 and 3 of the 1336 REGEN Line
Regeneration Package User Manual, publication 1336 REGEN-5.0.

1336 Regenerative DC Bus Supply Operation
Overview
When properly sized, the 1336 REGEN Line Regenerative Package represents an
amp-rated package that can provide a DC bus to one or more common bus drives
in the Regen DC Bus Supply mode.
General Precautions
ATTENTION: Only personnel familiar with the 1336 REGEN Line
Regeneration Package and associated equipment should plan or
implement the installation, start-up and subsequent maintenance of the
system. Failure to comply may result in personal injury and/or equipment
damage.
ATTENTION: Voltage distortion and possible component damage can
result from the voltage divider effect between AC line source impedance
and the 10% 1321 Line Reactor used with the 1336 REGEN Line
Regeneration Package. An additional power line filter must be used to
reduce AC line voltage distortion whenever source impedance is greater
than 10% of the per phase impedance supplied by the 10% line reactor. If
source impedance is unknown, the power line filter should be installed as
a general precaution.
ATTENTION: This product and its associated equipment contains ESD
(Electrostatic Discharge) sensitive parts and assemblies. Static control
precautions are required when installing, testing, servicing or repairing
this assembly. Component damage may result if ESD control procedures
are not followed. If you are not familiar with static control procedures,
reference publication 8000-4.5.2 "Guarding Against Electrostatic
Damage" or any other applicable ESD protection handbook.
ATTENTION: The 1336 REGEN Line Regeneration Package is shipped
from the factory with Parameter 1 [Operational Mode] set to the
Regenerative Brake Mode of operation. For Regenerative DC Bus Supply
applications, this parameter must be set to the Regenerative DC Bus
Supply Mode as described in the Programming section of this chapter.
Incorrectly applied or installed equipment can result in component
damage or a reduction in product life. Wiring or application errors, such as
incorrect or inadequate AC supply or excessive ambient temperatures
may result in malfunction of the Line Regenerative Package.

Power-up Sequence for Regenerative Brakes and AC Drives
When using a 1336 REGEN Line Regeneration Package, a power-up sequence is
needed to avoid clearing the AC line fuses on the input of the AC drive or the
DC bus fuses between the drive and the Regenerative Brake. These fuses will clear
if both the 1336 REGEN Package and the AC drive are powered up from the AC
supply simultaneously. To avoid the problem, the Regenerative Brake should be
powered up before the AC Drive is connected to the AC line. The 1336 REGEN
Precharge circuit will charge the capacitor bank in both the 1336 REGEN
Converter and in the connected AC drive. The AC line can then safely be
connected to the AC drive.

8720MC-RPS Regenerative Power Supply Package
It is important to properly plan before installing the 8720MC-RPS Regenerative
Power Supply to ensure that the environment and operating conditions of the
units are satisfactory. Read this section for important environment and operating
conditions information.
Environmental Conditions to be Met
The Declaration of Conformity with the requirements for CE Mark was issued
for the following units, and these units must be used in a cabinet.
• 8720MC-RPS027BM (no longer available)
• 8720MC-RPS065BM, 8720MC-RPS065BS
• 8720MC-RPS190BM and 8720MC-RPS190BS
Also, before deciding on an installation site, consider the following guidelines:
• Verify that the units can be kept clean, cool, and dry.
• Be sure that the units are always away from oil, metal powder, other
airborne contaminants, and direct sunlight.
• Check that the units will not be exposed to excessive vibration and noise,
and that they will not be close to instruments sensitive to electrical noise.
• The area chosen should allow the space required for proper air flow as
defined in Figure 36.
• Check that the temperatures within the vicinity of the units are between
10 to 50 °C (14 to 122 °F). In case of 8720MC-RPS190, however, the
ambient temperature must be between -10 to 40 °C (14 to 104 °F).
• Check that the relative humidity is between 5 and 95% without
condensation.
• Do not install the units above 1000 meters (3300 feet) without derating
output power. For every 300 meters (1000 feet) above 1000 meters
(3300 feet), derate the output power 4%. When you need to install the
units above 1500 meters (5000 feet), contact Rockwell Automation.

Power and Control Terminal 1336 REGEN Line Regeneration Package
Comparison
Input Power Conditioning
In general, 1336 REGEN equipment is suitable for direct connection to a
correct-voltage AC line. If the AC input power system does not have a neutral or
one phase referenced to ground, as detailed under Ungrounded Distribution
Systems (as described in the 1336 REGEN Line Regeneration Package User
Manual, publication 1336 REGEN-5.0), an isolation transformer with the
neutral of the secondary grounded is highly recommended. If the line-to-ground
voltages on any phase exceed 125% of the nominal line-to-line voltage, an
isolation transformer with the neutral of the secondary grounded is highly
recommended.
ATTENTION: The National Codes and standards (NEC, CENELEC, etc.)
and local codes outline the provisions for safely installing electrical
equipment. Installation must comply with specifications regarding wire
types, conductor sizes, branch circuit protection and disconnect devices.
Failure to do so may result in personal injury and/or equipment damage.
Grounding
All 1336 REGEN components must be connected to system ground at the PE
power ground terminal provided. Ground impedance must conform to the
requirements of national and local industrial safety regulations (NEC, VDE
0160, BSI, etc.), and should be inspected and tested at appropriate intervals. In
any cabinet, use a single low-impedance ground point or ground bus bar. Ground
all circuits independently and directly. Also, connect the AC supply ground
conductor directly to the ground point or ground bus bar.
Sensitive Circuits
It is essential to define paths through which high frequency ground currents flow
to ensure that sensitive circuits do not share a path with these currents. Do not
run control and signal conductors near or parallel to power conductors.
TE (True Earth) Termination
The converter’s TE terminals are used for all control signal shields internal to the
1336 REGEN Converter and must be connected to the converter’s TE terminals
by a separate continuous lead.
PE (Power Earth) Termination
A safety ground is required by code. This point must be connected to adjacent
building steel or a floor ground rod provided grounding points comply with
NEC and local regulations.

Control Board Connections
All customer control and signal wiring is made to quick-connect terminal blocks
J15 and J16.
The maximum/minimum wire sizes accepted by J15 and J16 is 3.3/0.6mm2
(12/30AWG). Maximum torque is 0.79N•m (7lb•in). Recommended control/
signal wire is:
• Belden® 8760 (or equivalent) — 0.750mm2 (18AWG), Twisted Pair,
Shielded.
• Belden 8770 (or equivalent) — 0.750mm2 (18AWG), Three-conductor,
Shielded.
• Belden 9460 (or equivalent) — 0.750mm2 (18AWG), Twisted Pair,
Shielded.
Note: If the converter control connections are to be linked to an electronic
circuit or device, the common or 0V line should be grounded at the drive end
only.
IMPORTANT
Signal common (DGND) puts the common or negative side of the signal at
earth ground potential. Control schemes must be examined for possible
conflicts.
All customer control and signal wiring shields are terminated at the TE terminal
block shown in Figure 60.
Cable Routing
If unshielded cable is used, control and signal circuits should not run parallel to
motor, DC bus, or unfiltered supply cables with a spacing less than 0.3 m (1 ft).
Cable tray metal dividers or separate conduit should be used.
IMPORTANT
If user-installed control and signal wiring with an insulation rating of less
than 600V is used, route the wiring inside the converter enclosure such
that is it separate from any other wiring or uninsulated live parts.

Digital Input Signals
ATTENTION: Ensure that all jumpers on the 1336 REGEN Converter
Control Board are set correctly prior to applying AC power to the board.
Applying 120VAC to the digital inputs when jumpers J10, J11, or J18 are
set to 24VDC will permanently damage the Converter Control Board.
IMPORTANT
Customer EXTERNAL FAULT and ENABLE circuits must be connected to
J15 and at logic high for the 1336 REGEN Converter to operate.
1336 REGEN Converter digital inputs are designed for operation at either
24VDC or 120VAC. Digital input signal circuits must be capable of operating
with high = true logic.
• For 24VDC operation, +24VDC is available from the 1336 REGEN
Converter Control Board.
• For 120VAC operation, a separate 120VAC user supply is required.

IMPORTANT
For Regenerative DC Bus Supply applications, the 1336 REGEN Line
Regeneration Package will be used with one or more common bus drives.
It is recommend that the fault relay on the 1336 REGEN Converter Control
board be interconnected into the common bus drive(s) control logic. This
will allow coordination the Regenerative DC Bus Supply faults with the
common bus drive.

External Fault
Allows a customer-supplied external signal to be wired into the 1336 REGEN
Converter. Opening this contact issues an external fault command, disabling the
converter.
External Reset
Resets the 1336 REGEN Converter when closed. If the converter has faulted,
closing this contact clears the fault and resets the converter.
Enable
For the 1336 REGEN Converter to modulate, an enable signal must be present at
J15 on the 1336 REGEN Converter Control Board. Opening this contact
disables the converter. When this contact is closed, the Enable LED on the
Control Board will be lit.
Digital Output Signals
Two form C, N.O./N.C. output relays are available at J16 on the 1336 REGEN
Control Board to provide external warning or fault change-of-state signals.

Fault Output - The fault output is used to indicate that
the 1336 REGEN Converter is faulted with either an
internal or external fault.
Note: The unpowered state of the fault relay is the
opposite of the faulted state—or the unpowered state
of the fault relay indicates an unfaulted condition.
Enable Output - The enable output indicates that the
1336 REGEN Converter is modulating. An enable
signal must be present on J15 and the 1336 REGEN
Converter must not be faulted for the enable output to
be active.
Interlocking 1336 REGEN Enable with AC Drive Enable
It may be desirable to interlock the 1336 REGEN Enable Output with the Enable
Input on the connected 1336 PLUS, 1336 PLUSII, 1336 IMPACT, or
1336 FORCE AC drive. This will keep the AC drive from starting if the
1336 REGEN Converter is not enabled, and will also remove the Enable signal
from the AC drive if the 1336 REGEN Converter is faulted. If the Enable signals
are not interlocked, the AC drive may fault on bus overvoltage when attempting
to regenerate.

8720MC-RPS Regenerative Power Supply
Installing DC Bus Power Output Wiring - All RPS units
ATTENTION: When connecting the DC bus to plural number of external
load equipment, the user is responsible for installing fuses to protect the
DC bus from shorting, if no fuse is provided in the load equipment. Failure
to observe this precaution could result in damage to, or destruction of, the
equipment.
ATTENTION: Exercise extreme caution for polarity of wiring when wiring
DC bus. Failure to observe this precaution could result in damage to, or
destruction of, the 8720MC-RPS Regenerative Power Supply and the
connected load equipment.
The DC bus output terminals on the main power terminal block (TB1) or the
DC bus terminal bars of the 8720MC-RPS Regenerative Power Supply are used
for connecting to load equipment such as an inverter. Use the recommended wire
size shown in Table 31 on page 93 and Table 32 on page 93 for wiring between
the 8720MC-RPS Regenerative Power Supply and the load equipment. Connect
the terminal P on the main power terminal block (TB1) or the terminal bar P of
the 8720MC-RPS Regenerative Power Supply to the positive (plus) DC bus
terminal of the load equipment, and the terminal N on the terminal block TB1 or
the terminal bar N to the negative (minus) DC bus terminal of the load
equipment. Do not connect the positive (plus) side with the wiring of the
negative (minus) side. Such miswiring will damage the 8720MC-RPS
Regenerative Power Supply and the connected load equipment.
When multiple drives are connected to the 8720MC-RPS Regenerative Power
Supply, we suggest you install input fuses before each drive (or refer to local code)
to protect the wiring and the drive. Select adequate fuse(s) for the drives.
Grounding the 8720MC-RPS Regenerative Power Supply
Connect an adequate equipment grounding conductor to ground terminal of
load equipment, remote control station (if used), input transformer (if used), and
ground terminal of the 8720MC-RPS Regenerative Power Supply. Run earth
conductor to earth ground after confirming that the conductors are unbroken.
This system is operated by switching DC bus line from + (plus) bus voltage
to - (minus) bus voltage viewing from the ground for the purpose of controlling.
For this reason, plus and minus voltages are always added on a circuit if
equipment has a circuit between the bus line of equipment to be connected and
the ground (earth). Even if no direct circuit exists between the bus line and the
ground, pulse current will flow through the stray capacity of the equipment by
bus voltage switching. When 8720MC-RPS and equipment to be connected to
8720MC-RPS are not securely grounded, this current will flow through the
circuit and may cause malfunction of them. If grounding is not made properly, it
will cause the malfunction of the other system on the same line.

Chapter 1
Comparison and Selection
Install an insulating transformer to the input line of the 8720MC-RPS if
unbalanced current flows and earth leakage breaker malfunctions due to the
power supply conditions.
For grounding, use the wire size of grounding terminal as shown in Table 31 on
page 93 and Table 32 on page 93
Wiring To Comply with Electromagnetic Compatibility (EMC)
To declare conformity with the requirements for CE Mark, 8720MC-RPS
Regenerative Power Supply must comply with both EMC directive and low
voltage directive. This section describes notes on wiring to comply with EMC
directive.
IMPORTANT
8720MC-RPS Regenerative Power Supply itself is not subject to Machine
directive. When 8720MC-RPS Regenerative Power Supply is combined
with other equipment, control cabinet and machine, it is needed to
declare the compliance with Machine directive. Noise level will vary
depending on the installation and wiring of 8720MC-RPS Regenerative
Power Supply, other equipment and control cabinet. It has been already
confirmed that 8720MC-RPS Regenerative Power Supply complies with
EMC standards only when 8720MC-RPS Regenerative Power Supply is
composed of the component parts designated by Reliance Electric. In
order for users to declare the conformity with the requirements for CE
Mark, do not fail to confirm that the unit complies with EMC standards
on the final conditions after completion of installation and wiring.
Table 24 shows the EMC standards compliance for the 8720MC-RPS
Regenerative Power Supply units.
Table 24 - 8720MC-RPS EMC Standards

2004/108/EC
EN 50178:1997
EN 61800-3:2004
8720MC-RPS190
Follow these guidelines for wiring to reduce the possibility of strong noise on the
input and output lines of the 8720MC-RPS Regenerative Power Supply.
1. Use a control cabinet made of metal for installing the 8720MC-RPS
Regenerative Power Supply (It has been confirmed that this unit complies
with EMC standards when installed inside the control cabinet).
2. Install a line filter designated by Reliance Electric to the power input line
of the 8720MC-RPS units. Wiring to the line filter must be as short as
possible.
80
Rockwell Automation Publication 1336R-AP001A-EN-P - July 2011
Comparison and Selection
Chapter 1
3. Because current will leak to the earth when a line filter is installed,
connection to the earth must be secured. Due to leaked current, the earth
leakage breaker may malfunction. Select a proper breaker complying with
leaked current (Rated current 100 to 500mA and operating time within
0.1 to 2 seconds).
4. The control cabinet must be securely grounded. Wiring to be taken into
grounding terminal of the control cabinet must be as thick and short as
possible.
5. The input and output line of the 8720MC-RPS units must be separated
from the output line of the inverter unit as far as possible.
6. Wiring of the control signal must be terminated within the control
cabinet. If the control cable needs to extend out of the control cabinet, it is
recommended to use shielded cables. When ferrite cores are used, install
them to the side of the 8720MC-RPS units. The following are the ferrite
cores for the control cables recommended.
• ZCAT2032-0930 (Inside diameter 9 +/- 1 mm): TDK
• ZCAT2035-1330 (Inside diameter 13 +/- 1 mm): TDK
7. For notes on wiring to the other equipment and motors to be connected
with the 8720MC-RPS, refer to the manuals of the relevant equipment.
Power Rating
Power rating of 8720MC-RPS Regenerative Power Supply depends on the
number of units connected in parallel as shown in Table 25. Up to three units can
be connected.

HIM Description
When the converter-mounted HIM is supplied, it is connected as Adapter 1 and
visible from the front of the converter. The display panel provides a means of
programming the 1336 REGEN Converter and viewing the various operating
parameters.
IMPORTANT
If a Control Panel HIM is connected to the 1336 REGEN Converter, only
the Start key and Stop key on the control panel will be functional — The
Start key will send an Enable command to the Converter, the Stop key
will send a Not Enable command to the Converter.
ATTENTION: When a HIM is not supplied on enclosed NEMA Type 1
(IP 20) 1336 REGEN Controllers, the blank cover plate (option HAB) must
be installed to close the opening in the front cover of the enclosure.
Failure to install the blank cover plate allows access to electrically live
parts which may result in personnel injury and/or equipment damage.
When a HIM is supplied with enclosed NEMA Type 1 (IP 20) 1336 REGEN
Converters but has been removed from its mounting cradle for remote
operation, the blank cover plate must be installed in its place.
HIM Removal
For handheld operation, the module can be removed and located up to 10 meters
(33 feet) from the 1336 REGEN Converter.
ATTENTION: Some voltages present behind the 1336 REGEN Converter
front cover are at incoming line potential. To avoid an electric shock
hazard, use extreme caution when removing/replacing the HIM.

The display on the operation panel consists of four seven-segment LEDs that
display monitored values, parameter numbers, parameter values, and error codes.
Six status LEDs on the operation panel display the operation status and the units
of the monitored values.
Operation Modes
The operation panel operates in the two modes:
• Monitor mode
• Program mode
In monitor mode, you can monitor various operating conditions including input
current of the 8720MC-RPS Regenerative Power Supply, DC bus voltage, etc. In
program mode, you can view and change parameter values, and examine the error
log.

Monitor Mode
Monitor mode is the operation mode to display operating conditions. The
following data can be displayed in this mode:
• Input current *
• AC input power voltage
• DC bus voltage
• Power
• Load ratio.
* The displayed value of input current is only an approximate value and no
accuracy can be guaranteed. If you need an accurate input current, measure it by
using a dedicated measuring device.
To select a value to monitor, press the ▲ key or the ▼ key until the desired
value is displayed. Pressing the ▲ key or the ▼ key will move you through the
each of the displays.
The unit of the displayed value is shown by turning ON the status LEDs as
follows:
• "A": Shows the unit when the input current is displayed.
• "V": Shows the unit when monitoring the AC input power voltage or the
DC bus voltage.
• "KW": Shows the unit when monitoring the power.
• Turning OFF all LEDs: Shows the unit when the load ratio is displayed.
In both cases of monitoring the AC input power voltage and the DC bus voltage,
the "V" status LED is ON. You can judge which item is being monitored, by the
display order. The unit of the load ratio is percent (%). But in this case, no status
LED is ON.
In case of monitoring the power, the "KW" status LED is ON continuously when
the operation is in power running, and the "KW" status LED flashes when the
operation is regenerative.
In monitor mode, the "PROGRAM" status LED is turned OFF, indicating that
the operation panel is not in program mode.
When any fault occurs, the operation panel cannot be changed to monitor mode.

Wiring Examples and Components
ATTENTION: Special caution must be paid to wiring to the 8720MC-RPS
Regenerative Power Supply when connecting multiple units in parallel.
The phases of AC input power to the main power supply terminals (L1, L2
and L3) and to the control power terminals (L1AUX, L2AUX, and L3AUX) and
the polarity of DC bus output (P and N) of all the connected units must be
the same. Failure to observe this precaution could result in destruction of
the equipment, severe bodily injury or loss of life.

It is possible to select the 8720MC-RPS units depending on the regenerative
power when only regenerated power of the unit integrating converter and
inverter is used. In this case, however, the following cautions must be observed.
Figure 82 shows wiring of the 8720MC-RPS065 unit used as a converter for the
power regeneration mode only.
• Rating of regenerative power of the 8720MC-RPS is less than rated power
both in the instantaneous rating and continuous rating.
• When rectifier portion of inverter is composed of thyristor, CR snubber
circuit between anode and cathode of thyristor may become overloaded.
Therefore, treating time for regenerative power must be within 5 seconds
for 3 minutes. Because the current "ICR" flowing through CR snubber
circuit in the power regeneration mode is represented by the following
formula, verify the specifications of CR snubber circuit.
–
I CR [A] = (8
0.03 x R [Ω]) x
C [μF]
• Do not fail to connect ACL unit of 3% impedance toward inverter rating
with the AC input line of inverter. Without ACL unit, excessive
circulating current will flow between the 8720MC-RPS units.
• Even during the power running, current will be supplied from the
8720MC-RPS unit to DC bus proportionally to the impedance ratio of
both reactors at the 8720MC-RPS unit and inverter. This current must
not exceed the rating of the 8720MC-RPS unit.
• Set the parameter of the FWD Current Limit (U.001) to zero (0).
• Set the parameter of the Discharging Function Enable (F.017) to zero
(OFF).
• Set the DC bus voltage to start power regeneration to the parameter of the
DC Bus Voltage Reference (U.000).
Rockwell Automation Publication 1336R-AP001A-EN-P - July 2011

Chapter 2
Wiring Examples and Components
• Open all the terminals PR1, PR2, and PR3 for connecting precharge/
discharge resistor. Because these terminals are open, the unit does not
perform precharge/discharge operations. Precharge/discharge must be
performed on inverter side.
• Do not fail to enter the READY signal of inverter to (PWR).
When Adapted to Capacitors Having Large Capacity
8720MC-RPS065 units charge to capacitors with a single phase, full-wave
rectification circuit through the built-in precharge/discharge resistor. When the
load capacitors have large capacitance, it takes more time for charging, and the
wattage of the internal resistor becomes insufficient. When the load capacitance
is large, disable the built-in precharge/discharge resistor and connect an external
resistor or external circuit for precharging/discharging (Note that minimum
precharging/ discharging cycle is 3 minutes).
Calculate the rated wattage of the external precharge/discharge resistor to be
connected to the outside in accordance with the following formula depending on

External Resistor Case
Most applications are successfully integrated using the internal precharge resistor
provided in the 8720MC-RPS Regenerative Power Supply. For instances where
there is a large amount of load capacitance, caused by connecting several
8720MC drives to a single 8720MC-RPS Regenerative Power Supply, an external
precharge resistor may be required. To determine the total capacitance C[F], add
the capacitance for the RPS065 unit as determined from row 1 of Table 36 to the
sum of the drive capacitance as determined by the drive specifications. If the total
capacitance of the RPS065 is above 7,000μf but less than 110,000μf, an external
resistor connected to PR1 and PR2 is required. Table 36 provides the minimum
resistance value for the external precharge resistor, 20 ohms for the RPS065. The
wattage [W] is determined by the equation presented above. Connect the
external precharge resistor to terminals PR1 and PR2 on terminal block TB2.
Terminal PR3 should be left open (see Figure 70). The Precharge/Discharge
Time (F.014) may require a larger value to accommodate the increased precharge
time. The Wattage of Precharge/Discharge Resistor (F.015) should also be
increased to the external precharge resistor wattage.
External Circuit Case
If the total capacitance of the RPS065 is above 110,000μf, but less than
220,000μf, an external resistor connected as shown in Figure 83 must be
provided. Table 36 provides the minimum resistance value for the external
precharge resistor: 4.7 ohms for the RPS065. The wattage [W] is determined by
the equation on page 109.

1> Remove the jumper between PR2 and PR3.
2> Because driving current of sequence input signals is 5mA and below, use a contact of which minimum applicable
load is 5mA and below.
3> Use the reactor in maximum surrounding air temperature of 55 °C (131 °F) and below.
If a totally external resistor network is used as shown in Figure 83, the calculated
wattage, [W] = 17,000 x C farads, is divided in half to size the precharge and
discharge resistors.
Note: Parameter F.015 should be set to the sum of the wattage for both resistors.

2> The phases of the AC input power to the main supply terminals L1, L2 and L3 must be same as those of the
control power to the control power terminals L1AUX, L2AUX and L3AUX.
3> It is recommended to install the DC bus protection fuses on the both lines to terminals P an N to prevent ground

4> Turn on the switch SW7-1 on the Regulator Board without fail.
5> Because driving current of sequence input signals is 5mA and below, use a contact of which minimum applicable
load is 5mA and below.
6> Use the ACL unit in maximum surrounding air temperature of 55 °C (131 °F) and below.
7> Open all the terminals PR1, PR2 and PR3 for connecting precharge/discharge resistor. Because these terminals
are open, the unit does not perform precharge/discharge operations. Precharge/discharge must be performed
on inverter side. Set the parameter of the Discharging Function Enable (F.017) to zero (OFF).
8> If you want the 8720MC-RPS unit to perform the precharge/discharge operation, Install Jumper PR2 to PR3 and
set Discharge Function Enable (F.017) to a one (ON).
It is possible to select the 8720MC-RPS units depending on the regenerative
power when only regenerated power of the unit integrating converter and
inverter is used. In this case, however, the following cautions must be observed.
Figure 87 shows wiring of the 8720MC-RPS190 unit used as a converter for the
power regeneration mode only.
• Rating of regenerative power of the 8720MC-RPS is less than rated power
both in the instantaneous rating and continuous rating.
• When rectifier portion of inverter is composed of thyristor, CR snubber
circuit between anode and cathode of thyristor may become overloaded.
Therefore, treating time for regenerative power must be within 5 seconds
for 3 minutes. Because the current "ICR" flowing through CR snubber
circuit in the power regeneration mode is represented by the following
formula, verify the specifications of CR snubber circuit.
–
I CR [A] = (8
0.03 x R [Ω]) x
C [μF]
• Connect ACL unit of 3% impedance toward inverter rating with the AC
input line of inverter. Without ACL unit, excessive circulating current will
flow between the 8720MC-RPS units.
• Even during the power running, current will be supplied from the
8720MC-RPS unit to DC bus proportionally to the impedance ratio of
both reactors at the 8720MC-RPS unit and inverter. This current must
not exceed the rating of the 8720MC-RPS unit.
• Set the parameter of the FWD Current Limit (U.001) to zero (0).
• Set the DC bus voltage to start power regeneration to the parameter of the
DC Bus Voltage Reference (U.000).
• Enter the READY signal of inverter to (PWR).

Precharge/Discharge Operation
• If you do not want the 8720MC-RPS unit to perform the precharge/
discharge operation, open all the terminals (PR1, PR2, and PR3) for
connecting the precharge/discharge resistor. In this case, the precharge/
discharge must be performed on inverter side. Set the Discharging
Function Enable parameter (F.017) to zero (OFF).
or
• If you do want the 8720MC-RPS unit to perform the precharge/discharge
operation, install a jumper from PR2 to PR3, and set the Discharge
Function Enable parameter (F.017) to one (ON).
When Adapted to Capacitors Having Large Capacity
8720MC-RPS190 unit charges to capacitors with a single phase, full-wave
rectification circuit through the built-in precharge/discharge resistor. When the
load capacitors have large capacitance, it takes more time for charging, and the
wattage of the internal resistor becomes insufficient. When the load capacitance
is large, disable the built-in precharge/discharge resistor and connect an external
resistor or external circuit for precharging/discharging (Note that minimum
precharging/discharging cycle is 3 minutes).
Calculate a rated wattage of the external precharge/discharge resistor to be
connected to the outside in accordance with the following formula depending on
the total capacitance of all the capacitors including the built-in capacitor.
• Rated wattage [W] = 17000 x C[F]
• But, serge resistivity of J[ J] = 28000 x C[F] must be provided.
When an external precharge/discharge resistor is connected, change the set value
of the following parameters, if necessary.
• Precharge/Discharge Time (F.014)
• Wattage of Precharge/Discharge Resistor (F.015)

External Resistor Case
Most applications are successfully integrated using the internal precharge resistor
provided in the 8720MC-RPS Regenerative Power Supply. For instances where
there is a large amount of load capacitance, caused by connecting several
8720MC drives to a single 8720MC-RPS Regenerative Power Supply, an external
precharge resistor may be required. To determine the total capacitance C[F] add
the capacitance for the applicable RPS190 unit, as determined from row 1 of
Table 37, to the sum of the drive capacitance as determined by the drive
specifications in Chapter 2 of the 8720MC Regenerative Power Supply
Installation Manual, publication 8720MC-RM001.
In the case of the RPS190 if the total capacitance is above 25,000μf, but less than
165,000μf, an external precharge resistor connected to PR1 and PR2 is required.
Table 37 provides the minimum resistance value for the external resistor of
10 ohms. The wattage is determined by the equation presented above. Connect
the external precharge resistor to terminals PR1 and PR2 on the terminal block
TB2. Terminal PR3 should be left open. See Figure 71 on page 85. The
Precharge/Discharge Time (F.014) may require a larger value to accommodate
the increased precharge time. The Wattage of Precharge/Discharge Resistor
(F.015) should also be increased to the external precharge resistor wattage.

External Circuit Case
In the case of the RPS190 if the total capacitance is above 165,000μf but less than
495,000μf an external precharge resistor connected as shown in Figure 88 must
be provided. Table 37 provides the minimum resistance value for the external
precharge resistor, 1.5 ohms in the case of the RPS190. The wattage [W] is
determined by the equation on page 118.

1> Remove the jumper between PR2 and PR3.
2> Use a relay with contact of which minimum applicable load is 5 mA and below.
3> Refer to the lower left corner of Figure 88 indicating the terminals on the ACL unit. When the fan inside the ACL
unit is connected with an external power supply, do not fail to connect with the power supply designated by
NEC Class 2 (Power supply limited to 100VA and below and 8A and below even in case of Error). Avoid the high
voltage portion and the high temperature portion of the ACL unit when wiring the fan inside the ACL unit.
4> Use the ACL unit in maximum surrounding air temperature of 55 °C (131 °F) and below.
If a totally external resistor network is used as shown in Figure 88, the calculated
wattage, [W] = 17,000 x C farads, is divided in half to size the precharge and
discharge resistors.
Note: Parameter F.015 should be set to the sum of the wattage for both resistors.

1336 REGEN Line
Regenerative Package
Overview
The 1336 REGEN Line Regeneration Package is designed so that factory default
parameter settings allow it to operate satisfactorily under a wide variety of load
and utility conditions.
IMPORTANT
The 1336 REGEN Package has been shipped from the factory with
Parameter 1 set to the Regenerative Brake Mode of operation. For
Regenerative DC Bus Supply applications, this parameter must be reset
as described in "Operational Mode" on page 2-29 of the 1336 REGEN Line
Regeneration Package User Manual, publication 1336 REGEN-5.0.
With the exception of Parameter 1, for the majority of applications there should
be no need to adjust parameters. Should utility or load conditions deviate from
the normal conditions listed in the specifications, the following parameters have
been provided to allow adjustments to factory settings.

Appendix B Sequence of Operation
Sequence Signal Wiring
Verify the following when installing sequence signal wiring:
• Twisted pair wires of 0.2 to 0.5 mm2 should be used for the signal line.
• Verify that the sequence signal wiring is separated from the power wiring
(main power supply wiring, control power wiring and DC bus power
wiring). Malfunction of the 8720MC-RPS Regenerative Power Supply is
possible if the control wires are separated from the AC and DC power
wires.
• Use a separate duct for the sequence signal wiring. It is recommended to
use a dedicated duct for the sequence signal wiring.
• Do not route the sequence signal wiring near any equipment which is
producing electromagnetic interference.
