Force Operation from Digital Operator

This function permits a digital operator interface to override the following two settings in the inverter:

A001 - Frequency source setting

A002 - Run command source setting

When using the [OPE] terminal input, typically A001 and A002 are configured for sources other than the digital operator interface for the output frequency and Run command sources, respectively. When the [OPE] input is ON, then user has immediate command of the inverter, to start or stop the motor and to set the speed.

Force Operation from Digital Operator

ON

Forces the operator interface to override:

 

A001 - Frequency Source Setting, and A002 - Run

 

Command Source Setting

Operations and Monitoring

Valid for inputs:

C001~C005

Required settings

A001 (set not equal to 00)

A002 (set not equal to 02)

 

Notes:

 

When changing the [OPE] state during Run Mode (inverter is driving the motor), the inverter will stop the motor before the new [OPE] state takes effect.

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.
