e Digital Output

e STM17 drives feature one optically isolated digital output. is output can be set to automatically con-

trol a motor brake, to signal a fault condition, to indicate when the motor is moving or to provide an output

frequency proportional to motor speed (tach signal). e output can also be turned on and o by program

instructions like Set Output. e output can be used to drive LEDs, relays and the inputs of other electronic

devices like PLCs and counters. e “OUT+” (collector) and “OUT-” (emier) terminals of the transistor are

available at the connector. is allows you to congure the output for current sourcing or sinking.

Note: If current is owing into or out of an output, the logic state of that output is low or closed. If no current is

owing, or the output is not connected, the logic state is high or open.

Do not connect the output to more than 30VDC.

e current through the output terminal must not exceed 40mA.
