0: Speed mode
1: Torque mode
Frequency
and torque
Output frequency range:0-upper limit frequency
Output frequency is controlled by giving
frequency. Output torque equal to load torque.
Output frequency range:0-upper limit frequency
Output frequency is not only limitedby giving
frequency, but also the load torque. While the
out torque is bigger than the giving torque,
frequency will reduce. Otherwise, the frequency
is milited by the giving frequency.

Features
and
application
Take motor speed as aim, quick repond to load
and keep stable speed. It is suitable where
need exact speed.
Take motor output torque as aim; keep stable
speed while with multi roll diameter calculation
functions. It can be for constant tension and
with tape winding and unwinding.
F0.02
Run command channel
Setting range: 0-3
Factory set: 0
It is channel for inverter receiving run and stop order and run direction. It is only used for starting and stopping control
under torque control.
0: Keyboard control
Inverter run and stop is controlled by keyboard key

REV/JOG
key is defined as reverse while
[F4.02]
set as “0” and jog while

set as “1”. Please refer to details of
[F4.02]
.
1: Terminal control
Factory default as two line mode 1 control mode. Under two line mode 1, inverter run, stop and
direction is controlled by whether “FWD” or “REV” set for
[F2.00-F2.07]
“multi function input terminal” connects to
control board terminal (COM) or not. “FWD” and “REV” definition refer to
[F2.00-F2.07]
. While under other control mode,
run, stop and direction refer to
[F2.12]
.
2: RS485 communication control
Inverter run, stop and direction is controlled by the signal received by RS485
communication terminal. Details refer to FD communication control parameter group and appendix 2: RS485
communication protocol.
3: Optional card
Inverter run, stop and direction is controlled by the signal received by optional card input signal. For
the optional card installation, parameter setting and soon, please refer use manual packing with the optional card.
Note: 1. While fault reset, key STOP/RESET, control terminal reset order and RS485 communication terminal are
valid reset order.
2. While inverter input frequency is 0Hz or lower than min output frequency [F1.26]. As long as you input
run order, keyboard FWD indicator will be on, the motor will run as 0 frequency.
Clew: keyboard key STOP/RESET function can be selectable. Under exterior terminal control or communication
control, it can be defined as stop function. Please refer to [F4.03]. Under exterior terminal control, if use
STOP/RESET to stop, inverter stops and close exterior terminal run order. It needs to input exterior
