Applied Motion STM23C-3CE - Manual (Page 34)

Programmable Output
The STM23 drives feature one optically isolated digital output. This output can be set to automatically control 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). The output can also be turned on and off by program instructions like
the Set Output (SO) command. The output can be used to drive LEDs, relays and the inputs of other electronic
devices like PLCs and counters. The output transistor’s collector, labeled OUT+, and emitter, labeled OUT-, are
available at the connector. This allows you to configure the output for current sourcing or sinking.
Diagrams of various connection types follow.
Do not connect the output to more than 30VDC.
The current through the output terminal must not exceed 40mA.
