Force Operation from Digital Operator

This function permits a digital operator interface to override the Run command source setting (A002) when it is configured for a source other than the operator interface. When the [OPE] terminal is ON and the operator interface gives a Run command, the inverter uses the standard output frequency settings to operate the motor.

•If the [OPE] input turns ON and the digital

operator gives a Run command while the inverter is already running, the inverter stops the motor. Then the digital operator can control the motor.
