Description
proportional gain or reducing integral time can
accelerate dynamic response of speed loop;
however, if the proportional gain is too large or
integral time is too small, system 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
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%
Setting range: 0–65535
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),
SVC mode 1 (P00.00=1), and closed-loop
vector control mode (P00.00=3).
