Specification of high-performance vector convertor
2: Asynchronous machine Complete tuning. As to ensure the dynamic control performance of the inverter,
choose full tuning, the motor must be separated from the load to keep the motor for the no-load condition.
Complete tuning process, the inverter will conduct static tuning, and then follow the acceleration time to
accelerate P0-17 to 80% of the motor rated frequency. After the holding period, P0-18 Deceleration
according to the deceleration time and stop the tuning is performed before the asynchronous machine
complete tuning, In addition to the need to set the motor type and motor nameplate parameters P1-00 ~ P1-
05, but also need to set the correct encoder type and encoder pulses P1-27, P1-28. Asynchronous machine
complete tuning, the drive can be obtained P1-06 ~ P1-10 five motor parameters and encoder AB phase
sequence P1-30, vector control current loop PI parameters P2-13 ~ P2-16.
Action Description: Set the function code is 2, then press the RUN key, the inverter will complete tuning.
P2 group: Vector control parameters
Function code in P2 group is only effective for vector control, not for VF control.

Drive is running at different frequencies, you can select a different speed loop PI parameters. When
operating frequency is smaller than the switching frequency 1 (P2-02), the speed loop PI adjustment
parameters are P2-00 and P2-01. When the operating frequency is greater than the switching frequency 2,
the speed loop PI adjustment parameters are P2-03 and P3-04. Speed loop PI parameters between
switching frequency 1 and switching frequency 2 are the two group of PI parameters linear switching.
