Then press
RUN
on the operation panel. The AC drive will drive the motor to accelerate/
decelerate and run in the forward/reverse direction, and the RUN indicator is ON. The auto-
tuning lasts approximately 2 minutes. When the preceding display information disappears
and the operation panel returns to the normal parameter display status, it indicates that the
auto-tuning is complete.
The AC drive will automatically calculate the following motor parameters:
Motor Parameter
Motor 1 )1-06: Stator resistance (asynchronous motor)
)1-07: Rotor resistance (asynchronous motor)
)1-08: Leakage inductive reactance (asynchronous motor)
)1-09: Mutual inductive reactance (asynchronous motor)
)1-10: No-load current (asynchronous motor)

(Asynchronous motor static tuning) and then press
RUN
on the operation panel. The motor
auto-tuning starts.
Note
In the synchronous motor system driven by MD380, and encoder for signal feedback is required.
Therefore, you need to set the encoder parameters correctly before the auto-tuning. During the
synchronous motor auto-tuning, the synchronous motor must rotate, and the best auto-tuning mode
is no-load dynamic auto-tuning. If it is not allowed, you can perform with-load dynamic auto-tuning.
4.9.3 Setting and Switchover of Multiple Groups of Motor Parameters
The AC drive supports switchover between four groups of motor parameters, namely, groups
