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.

Description
31 OPE Force Operation
from Digital
Operator ON Forces the operator interface to override:
A001 - Frequency Source Setting, and
A002 - Run Command Source Setting
OFF Parameters A001 and A002 are in effect again,
for the frequency source and the Run command
source, respectively
Valid for inputs:
C001, C002, C003, C004,
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.
