Description
PI parameters
(P23.00,P23.01)
P23.02
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.
Setting range of P23.00: 0.0–200.0
Setting range of P23.01: 0.000–10.000s
Setting range of P23.02: 0.00Hz–P23.05
Setting range of P23.03: 0.0–200.0
Setting range of P23.04: 0.000–10.000s
Setting range of P23.05: P23.02–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%
