Output Wiring

The ±Fault Output is an optically isolated transistor capable of driving a typical PLC input. The Fault Output

is normally on (conducts current) and turns off under the following conditions:

The Interlock jumper is missing on the motor connector

There is a short in the motor, either phase to phase or phase to ground

The heatsink temperature exceeds 90°C (195°F)

The driver is in its reset state and is not ready to accept pulses

Both ends of the output are uncommitted, so it can be wired as a sourcing or sinking output. The figure shows

a typical connection as a sourcing output.

LIMIT

A resistor may be needed to limit the current through the Fault Output. The value, and power rating of the

resistor is dependent on the value of Vdc, the voltage drop across the input, and the current requirements of

the input.
