L2002 Inverter

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.

• 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.
