SJ200 Inverter

Force Terminal Mode

The purpose of this intelligent input is to allow a device to force the inverter to allow control of the following two parameters via the control terminals:

•A001 - Frequency source setting (01 = control terminals [FW] and [RV]

•A002 - Run command source setting (01 = control terminals [O] or [OI]

Some applications will require one or both settings above to use a source other than the terminals. You may prefer to normally use the inverter’s keypad and potentiometer, or to use the ModBus network for control, for example. However, an external device can turn ON the [F-TM] input to force the inverter to (temporarily) allow control (frequency source and Run command) via control terminals. When the [F-TM] input is OFF, then the inverter uses the regular sources specified by A001 and A002 again.

•When changing the [F-TM] state during Run Mode

(inverter is driving the motor), the inverter will stop the motor before the new [F-TM] state takes effect.
