F7.15 Motor parameter identification
Setting range: 0~1
Motor parameter tuning function can start only under vector control
mode(F7.00=1).
0： Off
1： Static identification
During parameter tuning process, motor remains stop state and it
has no requirements on the connection relationship with motor shaft, but
the tuning accuracy is relatively low.
F7.16~ F7.18 Reserve
F7.19 Speed loop proportional coefficient
Setting range: 0.10~1.5
F7.20 Speed loop integral time
Setting range: 0.1~10.00
This parameter group is used to adjust the proportional gain, integral
time and differential coefficient of the speed regulator, please refer to
parameter setting principle as following:
1 ） Proportional gain P: when the value is bigger, the response is
faster, but its system stability is worse. Excessive gain may cause speed
oscillation.
2）Integral time constant 1: when the value is smaller, the response is
faster and speed overshoot is larger, then its system stability is worse.
Generally, this paramter is proportional to the system inertia. When the
inertia is large, the parameter value should be large too.
F7.21 Max. FWD torque limit
F7.22 Max. RED torque limit
Setting range: 0~200%
Setting range: 0~200%
