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

• - Run command source setting

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

Valid for inputs:
Required settings
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.
Permission for torque command input
This function is to permit the torque command input. (Please refer to chapter 3 for the
detailed description of the function.)
