oscillation and overshoot may occur; if
proportional gain is too 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: 0.0–200.0
Setting range of P03.01: 0.000–10.000s
Setting range of P03.02: 0.00Hz–P03.05
Setting range of P03.03: 0.0–200.0
Setting range of P03.04: 0.000–10.000s
Setting range of P03.05: P03.02–P00.03
(Max. output frequency)
0–8 (corresponding to 0–2^8/10ms)
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).

The values of the two function codes

are updated automatically after SM
parameter autotuning is completed.
