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.
Function

Speed-loop output
P03.06
The function code is used to set the filter time of the speed loop.

Braking slip compensation
P03.08
coefficient of vector control
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.

Note:
1. The two function codes impact the dynamic response speed and control accuracy of the system. Generally,
you do not need to modify the two function codes.
2. Applicable to SVC mode 1 (P00.00=1) only.
Function
code
P03.11
The function code is used to enable the torque control mode and set the torque setting method.
Note:
1. For setting methods 2–15, 100% corresponds to triple the motor rated current.
