Pre-excitation
flux
100.0%
100.0 to
500.0%
Adjust the flux supplied during the pre-
excitation time set in Cn.9.
The motor flux increases up to the rated flux
with the time constant as shown in Figure
Pre-excitation flux.
To reduce the time taken to reach the rated
flux, a higher motor flux base value than the
rated flux must be provided. When the
magnetic flux reaches the rated flux, the
provided motor flux base value is reduced.
NO
Cn.11
Power off
delay
0.00s
0.00 to
60.00s
After the motor stops, this parameter sets
the time during which direct current from the
drive is fed into the motor

0–5000
Adjust the proportional gain 1 of the speed
controller (low speed) for the permanent
magnet synchronous motor control. If the
speed deviation is greater than the torque,
the output command will increase
accordingly. With a high P value, the speed
is regulated faster. A very high value can
cause instability in speed.

Adjust the integral gain 1 of the speed
controller (low speed) for the permanent
magnet synchronous motor control. If the
speed deviation is greater than the torque,
the output command will increase
accordingly. With a high P value, the speed
is regulated faster. A very high value can
cause instability in speed.
