Hitachi X200 Series instruction manual 29, Force Operation from Digital Operator

4−29

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.

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

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.
