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.
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.
Torque Control
Enable
The torque control enable function is available in the
vector control with encoder feedback
mode (A044 = 05). You can use the inverter not only in speed control or pulse train position
control but also with the torque control function. Suitable applications include material winding
machines.
The torque command input is enabled when the [ATR] intelligent input (assigned with option
code 52) is ON. You can select one of four torque command input methods (digital operator
and three analog input terminals) by the torque command input selection.
