The speed loop dynamic response
characteristics of vector control can be adjusted
by setting the proportional coefficient and
integral time of speed regulator. Increasing
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.
P03.00 setting range: 0.0–200.0
P03.01 setting range: 0.000–10.000s
P03.02 setting range: 0.00Hz–P03.05
P03.03 setting range: 0.0–200.0
P03.04 setting range: 0.000–10.000s
P03.05 setting range: P03.02–P00.03 (Max.
output frequency)
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%
