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.

Function Name State Description
ON Forces A001=01 (frequency source setting =
control terminal), and A002=01(Run command
source setting = control terminal)

Mode
OFF Inverter applies the user setting for A001 and
A002 normally
Valid for inputs: C001~C005
Required settings A001, A002
Notes:
x 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.
Example (default input configuration shown—see
page 3–49):
See I/O specs on page 4–6.
Inverter Ready
The purpose of this intelligent input is to make the inverter ready to start the motor
immediately when the RUN command is given. When the RDY input is active, motor
output terminal is active even if there is no RUN command.
