Parameters of P03.00–P03.05 fit for vector control
mode only. Below P03.02, speed loop PI parameter is
P03.00 and P03.01; above P03.05, speed loop PI
parameter is P03.03 and P03.04; in between, PI
parameter is obtained by linear variation between two
groups of parameters, as shown below.
The speed loop dynamic response characteristics of
vector control can be adjusted by setting the
proportional coefficient and integral time of speed
regulator. Increase proportional gain or decrease
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.
Speed loop PI parameter is closely related to the
system inertial, users should make adjustment based
on default PI parameter according to different load
characteristics to fulfill different needs.
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)
Slip compensation coefficient is used to adjust the slip
frequency of vector control to improve speed control
precision. This parameter can be used to control speed
offset.
Setting range: 50–200%
