Frequency threshold for
injection current switching in
synchronous motor VF
control
When the synchronous motor VF control mode is
enabled, this parameter is used to set the
frequency threshold for the switching between input
current 1 and injection current 2.
Setting range: 0.0%–200.0% (of the motor rated
frequency)
Reactive current closed-loop
proportional coefficient in
synchronous motor VF
control
When the synchronous motor VF control mode
is enabled, this parameter is used to set the
proportional coefficient of the reactive current
closed-loop control.
Setting range: 0–3000
Reactive current closed-loop
integral time in synchronous
motor VF control
When the synchronous motor VF control mode
is enabled, this parameter is used to set the
integral coefficient of the reactive current closed-
loop control.
Setting range: 0–3000
Reactive current closed-loop
output limit in synchronous
motor VF control
When the synchronous motor VF control mode
is enabled, this parameter is used to set the
output limit of the reactive current closed-loop
control. A greater value indicates a higher
reactive closed-loop compensation voltage and
higher output power of the motor. In general,
you do not need to modify this parameter.
Setting range: 0–16000
Enable/disable IF mode for
asynchronous motor 1
Current setting in IF mode for
asynchronous motor 1
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%
Proportional coefficient in IF
mode for asynchronous motor
1
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
Integral coefficient in IF mode
for asynchronous motor 1
When IF control is adopted for asynchronous
motor 1, this parameter is used to set the
integral coefficient of the output current closed-
loop control.
Setting range: 0–5000
