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:
•
- Frequency source setting
A001
•
- Run command source setting
A002
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

Notes:
• 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.
