Programmable Outputs
The STAC5-S drives feature two digital outputs. These outputs 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). Or the outputs can be turned
on and off by program instructions like Set Output. -Q and -IP drives include four additional
programmable outputs.
The outputs can be used to drive LEDs, relays and the inputs of other electronic devices like
PLCs and counters. For Y1, Y2 and OUT4, the “+” (collector) and “-” (emitter) terminals of each
transistor are available at the connector. This allows you to configure each output for current sourcing or sinking. OUT1, OUT2 and
OUT3 can only sink current. The COM terminal must be tied to power supply (-).
Diagrams of each type of connection follow.
Do not connect the outputs to more than 30VDC.
The current through each output terminal must not exceed 100 mA.
