Hitachi CONVENTION 14 instruction manual 4 29

Force Operation from Digital Operator
This function permits a digital operator interface to override the following two settings
in the inverter:
xA001 - Frequency source setting
xA002 - 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.

OFF Parameters A001 and A002 are in effect again,
for the frequency source and the Run command
source, respectively
Validfor inputs: C001~C005
Requiredsettings A001 (set not equal to 00)
A002 (set not equal to 02)
Notes:
xWhen 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.
xIf 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.
