Force Operation from Digital Operator
This function permits a digital operator interface to override the following two settings
in the inverter:


- Frequency source


- Run command source
When using the [OPE] terminal input, typically A001 and

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.

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.
