Programmable Outputs
The ST 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 devices 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.
