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.

Description
51 F-TM Force Terminal
Mode
ON Forces A001=01 (frequency source setting =
control terminal), and
A002=01(Run command source setting = control
terminal)
OFF Inverter applies the user setting for A001 and
A002 normally
Valid for inputs:
C001, C002, C003, C004,
C005
Required settings:
A001, A002
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.
