Programmable Outputs
The STP drives feature four digital outputs. These outputs can be set to automically
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). Or the
outputs can be turned on and off by program instructions like Set Output.
The outputs can be used to drive LEDs, relays and the inputs of other electronic de-
vices like PLCs and counters. For Y4, the “+” (collector) and “-” (emitter) terminals of
each transistor are available at the connector. This allows you to configure this output
for current sourcing or sinking. The Y1-3 outputs can only sink current. The Y 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.
