P03.00

ASR proportional gain 1

The   parameters of P03.00–P03.05 are applicable only to the vector control mode.   When the frequency is lower than P03.02 (Low-point frequency for switching),   the ASR PI parameters are P03.00 and P03.01. When the frequency is higher   than P03.05 (High-point frequency for switching), the ASR PI parameters are P03.03   and P03.04. When the frequency is between P03.02 and P03.05, the PI   parameters are obtained based on the linear change of these two groups of   parameters, as shown in the following figure.

You can   adjust the dynamic response characteristics of the automatic speed regulator   (ASR) in vector control by setting the ASR proportional gain and integral   time. Both increasing the proportional gain and decreasing the integral time   can accelerate the dynamic response of the ASR. However, if the proportional   gain is too large or the integral time is too short, system oscillation or   overadjustment may be caused. If the proportional gain is too small, system   steady-state oscillation may be easily caused, and static speed error may   also occur.

The ASR   PI parameters are closely related to the inertia of the system. The default   PI parameters need to be modified based on the characteristics of loads to   meet requirements of various scenarios.
