P13.15 ACR Proportional Gain2
P13.16 ACR Integral Time2
ACR：Automatic current regulator.
ACR parameters adjust the PI adjustment parameter of the current loop which affects the dynamic response
speed and control accuracy directly. Generally, users do not need to change the default value;
Only apply to the vector control mode without PG card (P00.04=0).

0～100improve the dynamic response of vector
control,
0.0%～50.0%improve the dynamic response of
weak magnetic curvature.
0.001s-5.000s
50%-200%
For sensorless vector control, this parameter is
used to adjust the speed stabilizing precision of
the motor.
When the speed is too low due to heavy load of
motor, this parameter needs to be enlarged, vice
versa.
