Set the parameters according to the motor nameplate no matter whether V/F control or vector
control is adopted.
To achieve better V/F or vector control performance, motor auto-tuning is required. The motor
auto-tuning accuracy depends on the correct setting of motor nameplate parameters.

The parameters in d0.08 to d0.15 are asynchronous motor parameters. These parameters are
unavailable on the motor nameplate and are obtained by means of motor auto-tuning. Only d0.08 to
d0.10 can be obtained through static motor auto-tuning. Through complete motor auto-tuning, encoder
phase sequence and current loop PI can be obtained besides the parameters in d0.08 to d0.12.Each
time "Rated motor power" (d0.01) or "Rated motor voltage" (d0.02) is changed, the AC drive
automatically restores values of d0.08 to d0.12 to the parameter setting for the common standard Y
series asynchronous motor.
If it is impossible to perform motor auto-tuning onsite, manually input the values of these
parameters according to data provided by the motor manufacturer.
