Settings 0 to 150% (0: disable)
It is used to control the response speed for the flux weakening area. The larger number you
set, the faster response you will get.

This parameter is used to set resonance frequency of mechanical system. It can be used to
suppress the resonance of mechanical system.
The larger number you set Pr.11-13, the better suppression resonance function you will get.
The notch filter frequency is the resonance of mechanical frequency.
11-15 Gain Value of Slip Compensation Unit: 0.01
Control
mode
SVC
Factory Setting: 1.00
Settings 0.00 to 1.00
It is only valid in SVC mode.
When the AC motor drive drives the asynchronous motor, slip will increase when the load is
added. This parameter can be used to change frequency, lower slip and make the motor be
synchronous when running under rated current. When the output current is higher than no-load
current, the AC motor drive will adjust frequency by this parameter. If the actual speed is
slower than expected, please increase the setting or decrease the setting.
