Input current 1 in
synchronous motor
V/F control
When the synchronous motor V/F 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 rated
current of the motor)
20.0%
P04.35
Input current 2 in
synchronous motor
V/F control
When the synchronous motor V/F 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 rated
current of the motor)

for input current
switching in
synchronous motor
V/F control
When the synchronous motor V/F control mode is
enabled, this parameter is used to set the
frequency threshold for the switching between input
current 1 and input current 2.
