P04.46
Current setting in IF mode for
asynchronous motor 2
When IF control is adopted for asynchronous
motor 2, this parameter is used to set the output
current. The value is a percentage in relative to
the rated current of the motor.
Setting range: 0.0–200.0%
120.0%
P04.47
Proportional coefficient in IF
mode for asynchronous motor
2
When IF control is adopted for asynchronous
motor 2, this parameter is used to set the
proportional coefficient of the output current
closed-loop control.
Setting range: 0–5000
350
P04.48
Integral coefficient in IF mode
for asynchronous motor 2
When IF control is adopted for asynchronous
motor 2, this parameter is used to set the
integral coefficient of the output current closed-
loop control.

5.5.5 Torque control
The VFD supports torque control and speed control.
Speed control mode aims to stabilize the speed to keep the set speed consistent with the actual
running speed. Meanwhile, the max. load-carrying capacity is restricted by torque limit.
Torque control mode aims to stabilize the torque to keep the set torque consistent with the actual
output torque. Meanwhile, the output frequency is restricted by upper/lower limit.
