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%
Note:
1. These two parameters are used to adjust PI
parameters of current loop; it affects dynamic
response speed and control precision of the
system directly. The default value needs no
adjustment under common conditions;
2. Fit for SVC mode 0 (P00.00=0) , SVC mode
1 (P00.00=1) and FVC mode (P00.00=3);
Setting range: 0–65535
