Parameter Group
-228-
Description
In SVC control mode (F0-01 = 0), the speed loop feedback filter time is valid. You can improve the
stability of the motor by adjusting this parameter. Increasing the speed loop feedback filter time can
enhance motor stability but slow down dynamic response. Decreasing it will bring faster dynamic
response. An excessively small parameter value may lead to motor oscillation.
Generally, the motor stability meets requirements, and no adjustment is required.

Description
0: Digital setting (F2-10)
The torque upper limit in speed control mode is set by F2-10 (digital setting of torque upper limit in
speed control).
1: AI1
The torque upper limit is input with the current or voltage signal through the AI1 terminal. The
frequency is calculated according to the preset AI curve.
2: AI2
The torque upper limit is input with the current or voltage signal through the AI2 terminal. The
frequency is calculated according to the preset AI curve.
3: AI3
The torque upper limit is input with the current or voltage signal through the AI3 terminal. The
frequency is calculated according to the preset AI curve.
5: Communication
The main frequency is set through communication. The running frequency is input through remote
communication. The AC drive must be equipped with a communication card to implement
communication with the host controller. This mode applies to remote control or centralized control
systems of multiple equipment.
