small, stable oscillation or speed offset may
occur.
PI parameters have a close relationship with the
inertia of the system. Adjust PI parameters
depending on different loads to meet various
demands.
Setting range of P03.00: 0–200.0
Setting range of P03.01: 0.000–10.000s
Setting range of P03.02: 0.00Hz –P03.05
Setting range of P03.03: 0–200.0
Setting range of P03.04: 0.000–10.000s

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.
 The parameters P03.09 and P23.05 are
applicable only to SVC 0 (P00.00=0).
Setting range: 0–65535
