Warnings
1.4 Warnings
This development tool set operates in an environment that includes dangerous
voltages and rotating machinery.
To facilitate safe operation, input power for the high-voltage power stage
should come from a current-limited dc laboratory power supply, unless power
factor correction is specifically being investigated.
Freescale Semiconductor, Inc...
When operating from an ac line, power stage grounds and oscilloscope grounds
are at different potentials, unless the oscilloscope is floating. Note that probe
grounds and, therefore, the case of a floated oscilloscope are subjected to
dangerous voltages.
The user should be aware that:
•
Before moving scope probes, making connections, etc., it is generally
advisable to power down the high-voltage supply.
•
When high voltage is applied, using only one hand for operating the test
setup minimizes the possibility of electrical shock.
•
Operation in lab setups that have grounded tables and/or chairs should be
avoided.
•
Wearing safety glasses, avoiding ties and jewelry, using shields, and
operation by personnel trained in high-voltage lab techniques are also
advisable.

Introduction and Setup
1.5 Setup Guide
Setup and connections for the optoisolation board are straightforward. The
optoisolation board connects to a Motorola embedded motion control series
high-voltage power stage via a 40-pin ribbon cable with a Motorola embedded
motion control series control board to form a mother/daughter board
arrangement. Figure 1-3 depicts a completed setup.
Follow these steps to set up the board:
Freescale Semiconductor, Inc...
1. Mount four standoffs to the optoisolation board at the locations indicated
in Figure 1-3. Standoffs, screws, and washers are included in the
ECOPT kit. This step and step 3 are optional when making connections
with DSP control boards such as the DSP56F805EVM. The DSP boards
may be placed flat on a bench, next to the optoisolation board.
2. Plug one end of the 40-pin ribbon cable that is supplied with Motorola
embedded motion control series control boards into input connector J2,
labeled “control board.”
3. Mount the control board on top of the standoffs with screws and washers
from the ECOPT kit. This step is optional with DSP control boards.
4. Plug the free end of the cable connected to input connector J2 into the
control board’s 40-pin connector.
5. Plug one end of the ECOPT kit’s 40-pin ribbon cable into output
connector J1, labeled “power stage.” The other end of this cable goes to
the power stage’s 40-pin input connector.
6. Connect a 12-Vdc power supply either to connector JP1, labeled “Ext.
Power 12V DC,” or power jack J3. Either one, but not both, may be used.
These connectors are located immediately above 40-pin connector J2 on
the right side of the optoisolation board. The 12-volt power supply
should be rated for at least 1 amp.
7. Apply power first to the optoisolation board, and then to the power stage.
Note that the optoisolation board powers the control board and that the
optoisolation board is not fully powered until power is applied to the
power stage.

2.2 Introduction
Motorola’s embedded motion control series optoisolation board links signals
from a controller to a high-voltage power stage. The board isolates the
controller, and peripherals that may be attached to the controller, from
dangerous voltages that are present on the power stage. The optoisolation
board’s galvanic isolation barrier also isolates control signals from high noise
in the power stage and provides a noise-robust systems architecture.
Signal translation is virtually one-for-one. Gate drive signals are passed from
controller to power stage via high-speed, high dv/dt, digital optocouplers.
Analog feedback signals are passed back through HCNR201 high-linearity
analog optocouplers. Delay times are typically 250 ns for digital signals, and
2 µs for analog signals. Grounds are separated by the optocouplers’ galvanic
isolation barrier.
Both input and output connections are made via 40-pin ribbon cable connectors.
The pin assignments for both connectors are the same. For example, signal
PWM_AT appears on pin 1 of the input connector and also on pin 1 of the
output connector. In addition to the usual motor control signals, an
MC68HC705JJ7CDW serves as a serial link, which allows controller software
to identify the power board.
Power requirements for controller side circuitry are met with a single external
12-Vdc power supply. Power for power stage side circuitry is supplied from the
power stage through the 40-pin output connector.

3.2 Introduction
Inputs and outputs are located on four connectors. They are listed as follows.
Location descriptions assume that the board is oriented such that its title is read
from left to right.
•
J2 — Signal inputs are grouped together on 40-pin ribbon cable
connector J2, located on the right side of the board.
•
J1 — Signal outputs are provided on 40-pin ribbon cable connector, J1,
located on the left.
•
JP1 and J3 — Two connectors, labeled JP1 and J3, are provided for the
12-volt power supply. JP1 and J3 are located immediately above input
connector J2. Power is supplied to one or the other, but not both.
Pin assignments for the input and output connectors are shown in Figure 3-1
and Figure 3-2. In these figures, a schematic representation appears on the left,
and a physical layout of the connector appears on the right. The physical view
assumes that the board is oriented such that its title is read from left to right.
Signal descriptions are provided in Table 3-1. Note that each signal has the
same pin assignment on both connectors. Power supply and ground connections
go to different power supplies, due to the isolation barrier. However, pin
locations for similar power supply voltages remain the same. For example, +15
volts on the input connector and +15 volts on the output connector come from
physically different power supplies, but occupy pin 19 on both connectors.

4.2 Overview
A set of schematics for the optoisolation board appears in Figure 4-1 through
Figure 4-9. An overview of the whole board is shown in Figure 4-1. Digital
isolation blocks appear in Figure 4-2 through Figure 4-4. Analog isolation
blocks are shown in Figure 4-5 through Figure 4-7. The serial link appears in
Figure 4-8, and an on-board power supply that converts +12 volts into +5 V,
+3.3 V, +15 V and –15 V is shown in Figure 4-9.
Unless otherwise specified, resistor values are in ohms, resistors are specified
as 1/8 watt ± 5%, and interrupted lines coded with the same letters are
electrically connected.
The high-level schematic in Figure 4-1 identifies individual signals with the
same designation upon both entering and leaving the board. For example,
temperature sense signal “Temp_sense” comes into the board on pin 26 of
connector J2, leaves on pin 26 of J1, and is labeled “Temp_sense” in both
places. Since the power supplies connected to J1 and J2 are physically different,
power supply and ground designations include “_PS” or “_CB.” “_PS” refers to
the power stage side of the isolation barrier. Similarly, “_CB” refers to the
control board side of the isolation barrier. For example, the +15-volt analog
supply is labeled “+15V_A_CB” on pin 19 of input connector J2. Similarly, the
+15-volt connection on pin 19 of output connector J1 is labeled “+15V_A_PS.”

In the detail-level schematics, signals also get “_CB” or “_PS” adders to
indicate which connector they are coming from. For example, the signal
identified as “Temp_sense” in high-level schematic Figure 4-1 appears on the
left-hand side of Figure 4-6 as “Temp_sense_PS.” The “_PS” adder indicates
that the signal “Temp_sense” at the input to U500A comes from output
connector J1. Similarly, “Temp_sense_CB” on the right hand side of
Figure 4-6 indicates that a connection is made to input connector J2.

5.2 Overview
From a systems point of view, the optoisolation board fits into an architecture
that is optimized for noise robustness. All drive and feedback signals that flow
between the processor and power stage are optocoupled. This configuration
physically separates the processor’s ground from the power stage, where di/dt’s
of 100 A/ns are not uncommon.
The optoisolation board transfers 14 digital signals, nine analog signals, and one
bidirectional signal across a galvanic isolation barrier. Digital signals use a
common circuit block, which is repeated once for each signal. Similarly, the
analog circuitry uses a common block that is repeated. Descriptions of each of
these blocks are contained in the following subsections.

5.3 Digital Optoisolation Block
The digital optoisolation block is relatively straightforward. It is based on
Agilent Technologies’ HCPL-J454 high dv/dt coupler. A simplified schematic
is shown in Figure 5-1.

Figure 5-1. Simplified Digital Isolation Block
At the input, pull-down resistor R1, sets a logic low in the absence of a signal.
Open input pull-down is important for gate drive signals, where it is desirable
to keep power transistors off in case of either a broken connection or absence of
power on the control board.
Next, NAND gate U1A, inverts the input signal. Assuming a logic low at the
input, U1A’s output is high, which puts both the anode and cathode of the
optocoupler’s input diode at +5 volts. With no forward bias on the input diode,
the optocoupler’s output transistor is off, producing a logic high. This logic high
is inverted by U2B to produce a logic low at the output. Conversely, when the
input is high, the output of U1A is low, which forward biases the optocoupler’s
input diode. Forward bias at the input causes light to shine on photodiode D2,
which produces a leakage current that flows into Q1’s base. With base current
supplied, Q1 is on, the optocoupler’s output is low, and the output of U2B is
high. The block as a whole, therefore, is non-inverting. In other words, a logic
high at the input produces a logic high at the output.
HCPL-J454 optocouplers have been selected for their noise immunity and high
dv/dt withstand capability. They provide a robust buffer between power stage
noise and the control circuitry.

Analog Optoisolation Block
5.4 Analog Optoisolation Block
Freescale Semiconductor, Inc...
A simplified schematic of the analog optoisolation block is shown in
Figure 5-2.
It is based upon Agilent Technologies’ HCNR201 high-linearity optocoupler.
The HCNR201 consists of an LED and two photodiodes. The LED and one of
the photodiodes (PD1) is on the input side of the optoisolation barrier, and the
other photodiode (PD2) is on the output side. The package is constructed so that
each photodiode receives approximately the same amount of light from the
LED. Feedback amplifier A1 is configured with PD1 to monitor the light output
of the LED and automatically adjust LED current to compensate for any
non-linearity. The output photodiode then converts the LED’s stable, linear
light output into a current, which is then converted back into a voltage by
amplifier A2.

Figure 5-2. Simplified Analog Isolation Block
Circuit operation may not be immediately obvious from inspecting Figure 5-2,
particularly the input part of the circuit. Stated briefly, amplifier A1 adjusts
LED forward current (IF) such that the current in PD1 (IPD1) is equal to VIn/R1.
Analysis of the input circuit reveals that increasing the input voltage increases
the voltage at the inverting input terminal of A1. Amplifier A1 amplifies that
increase, causing IF and IPD1 to increase. Given the way that PD1 is connected,
IPD1 will pull the inverting input of the op-amp back toward ground. A1 will
continue to increase IF until its inverting input voltage stabilizes near its ground
reference voltage. Assuming that no current flows into the inputs of A1, all of
the current flowing through R1 will flow through PD1. Since the inverting input
of A1 is at approximately 0 volts, the current through R1, and therefore IPD1, is
equal to VIn/R1. Essentially, amplifier A1 adjusts IF such that IPD1 = –VIn/R1.

Note that IPD1 depends only on the input voltage and the value of R1 and is
independent of the optocoupler’s characteristics. Also note that IPD1 is directly
proportional to VIn, giving a very linear relationship between the input voltage
and the photodiode current.
The physical construction of the optocoupler’s package determines the relative
amounts of light that fall on the two photodiodes and, therefore, the ratio of the
photodiode currents. This results in a current, IPD2, that is nearly equal to IPD1.
Amplifier A2 and resistor R3 form a trans-resistance amplifier that converts
IPD2 back into a voltage, VOut, where VOut = IPD2 × R3. Combining input and
output equations results in an expression that relates the output voltage to the
input voltage, VOut /VIn = (R3/R1). Therefore, with R1 = R3, the output signal
closely matches the input.
5.5 Serial Link
The serial link connected to pin 30 of connector J1 is somewhat different than
the other digital links in that it is capable of transferring signals in both
directions. Figure 5-3 shows that two optocouplers are used to provide
bidirectional signal transfer. On the left hand side of Figure 5-3, the open
collector of optoisolator ISO801 is tied to the input of U300D and pullup
resistor R800. This wired-OR configuration allows transfer of an input signal
when ISO801 is off, and also it allows output signals to pass through ISO801,
when an input signal is not present. On the other side of the isolation barrier, the
output of ISO800 and the input of ISO801 go to separate digital ports, providing
for signal transfer in both directions.
