P04.35
Current setting in
IF mode for
asynchronous
motor
When IF control is adopted for asynchronous
motor 1, 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%

P04.36
Proportional
coefficient in IF
mode for
asynchronous
motor
When IF control is adopted for asynchronous
motor 1, this parameter is used to set the
proportional coefficient of the output current
closed-loop control.
Setting range: 0–5000

P04.37
Integral
coefficient in IF
mode for
asynchronous
motor
When IF control is adopted for asynchronous
motor 1, this parameter is used to set the inetgral
coefficient of the output current closed-loop
control.
Setting range: 0–5000

P04.38
Frequency
threshold for
switching off IF
mode for
asynchronous
motor 1
When IF control is adopted for asynchronous
motor 1, this parameter is used to set the
frequency threshold for switching off the output
current closed-loop control. When the frequency
is lower than the value of this parameter, the
current closed-loop control in the IF control mode
is enabled; and when the frequency is higher than
10.00Hz
