Using Intelligent Input Terminals
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.

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.
