Injection 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
Injection 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)

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 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
