Using Intelligent Input Terminals Section 4-5
4-5-19 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 con-
trol terminals. When the [F-TM] input is OFF, then the inverter uses the regu-
lar sources specified by
A001 and A002 again.
4-5-20 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.)

ON Forces A001=01
(frequency source setting = control

OFF Inverter applies the user setting for
A001 and A002 normally
Valid for inputs: C001~C007

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.
