P04.34
Pull-in current 1 in
synchronous motor
VF control
When the synchronous motor VF control mode is
enabled, this parameter is used to set the reactive
current of the motor when the output frequency is
lower than the frequency set in P04.36.
Setting range: -100.0%
–+100.0% (of the motor
rated current)
20.0%
P04.35
Pull-in current 2 in
synchronous motor
VF control
When the synchronous motor VF control mode is
enabled, this parameter is used to set the reactive
current of the motor when the output frequency is
higher than the frequency set in P04.36.
Setting range: -100.0%
–+100.0% (of the motor
rated current)
10.0%
P04.36
Frequency threshold
for pull-in 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 pull-in current 2.
Setting range: 0.0%
–200.0% (of the motor rated
frequency)
20.0%

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.

P04.38
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

P04.39
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
