Slip compensation coefficient is used to
adjust the slip frequency of the vector
control and improve the speed control
accuracy of the system. Adjusting the
parameter properly can control the speed
steady-state error.
Setting range: 50–200%
Note:
The two function codes impact the
dynamic response speed and control
accuracy of the system. Generally, you do
not need to modify the two function codes.
Applicable to SVC mode 0 (P00.00=0)
and closed-loop vector control mode
(P00.00=3).

0.00–10.00s
In the closed-loop vector control mode
(P00.00=3), when the frequency is lower
than
the
switching
current-loop PI parameters are P23.09 and
P23.10; and when the frequency is higher
than
the
switching threshold, the current-loop PI
parameters are P23.12 and P23.13.
Setting range of P23.12: 0–65535
Setting range of P23.13: 0–65535
Setting range of P23.14: 0.0–100.0% (of the
max. frequency)
