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.

ON

Forces A001=01 (frequency source setting =
control terminal), and A002=01(Run command

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

):

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.

OFF

Inverter performs normal start when the RUN
command is given.

Valid for inputs:

Required settings

A001, A002

Notes:

HIGH VOLTAGE: When RDY function is set ON, there will be a voltage at motor
output terminals U, V and W even if the motor is in stop mode. Never touch the
inverter power terminals while the inverter is powered up.
