2.10: Outputs, XEL/XPL/XML
The Xenus Plus XEL, XPL and XML drives have 6 programmable digital outputs (one opto-isolated
and five non-isolated) and one programmable analog output.
The XEL/XPL/XML features six programmable digital outputs. OUT1~5 are general-purpose
outputs. OUT6 is specifically designed as a brake output but can be programmed for other
functions. For a list of digital output functions, see Control I/O (p. 107)
OUT1~OUT3 are connected on J8. Opto-isolated OUT4 and OUT5 are on J9. OUT6 (Brake) is on
J4.
OUT1 and OUT2 are current sinking MOSFETs, each with a pull-up resistor, in series with a diode,
connected to the drive’s internal +5 Vdc supply. This design allows the outputs to be directly
connected to optically isolated PLC inputs that reference a voltage higher than +5 Vdc, typically
+24 Vdc. The diode prevents current flow between the +24 Vdc supply and the internal +5 Vdc
supply though the pull-up resistor. This current, if allowed to flow, could turn on the PLC input,
giving a false indication of the drive’s true output state. OUT1 and OUT2 require an external flyback diode to be installed across any inductive loads, such as relays, that are connected to them.
OUT3 is a 5V high speed buffered CMOS output.
OUT4 and OUT5 are opto-isolated Darlingtons with a 30 Vdc maximum output. Zener clamping
diodes across outputs allow driving of resistive-inductive (R-L) loads without external flyback
diodes. The outputs are two-terminal and for connection to +24V or ground to source or sink
current. The output current rating is 20 mA.
The brake output (OUT6) is described below in Brake Operation.
There is one programmable analog output (AOUT1). It has an output voltage range of ±5 Vdc. An
op-amp buffers the output of a 12-bit D/A converter.
2.11: Outputs, XE2/XP2/XM2/800-1818/800-1819
XE2/XP2/XM2/800-1818 models have 7 programmable digital outputs, while the 800-1819 has 5.
OUT1~OUT5 are opto-isolated, two-terminal SSR (Solid State Relay) switches, each with a series
resistor and Zener clamping diodes across the outputs allow driving of resistive-inductive (R-L)
loads without the need for external flyback diodes.
The 800-1819 does not utilize OUT 4~5. For a list of digital output functions, see the CME 2 User
Guide. Brake outputs (OUT6 and OUT7), are isolated, open-drain MOSFETs with internal flyback
diodes connected to the +24 Vdc input. OUT6 and OUT7 are specifically designed as brake
outputs for axis A and B respectively, but can be programmed to perform other functions.
There are no analog outputs in XE2/XP2/XM2/800-1818/800-1819.
2.12: Brake Operation
Digital Output Controls Brake
Many control systems employ a brake to hold the axis when the drive is disabled. Xenus Plus
drives have digital outputs designed specifically for brake outputs. Other outputs can be used but
these are recommended. Unlike the other outputs, these brake specific outputs are optically
isolated from the control signals and have internal fly back diodes connected to the +24 Vdc input.
By eliminating the need to connect into the drive control connector, having the brake output on the
+24 Vdc power connector simplifies wiring when the brake wires are in the power cable of the
motor.
