MD380 User Manual Operation, Display and Application Example

- 71 -

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 F1-06: Stator resistance (asynchronous motor)

F1-07: Rotor resistance (asynchronous motor)

F1-08: Leakage inductive reactance (asynchronous motor)

F1-09: Mutual inductive reactance (asynchronous motor)

F1-10: No-load current (asynchronous motor)

Motor 2 A2-06 to A2-10, dened the same as F1-06 to F1-10

Motor3 A3-06 to A3-10, dened the same as F1-06 to F1-10

Motor 4 A4-06 to A4-10, dened the same as F1-06 to F1-10

If the motor cannot be disconnected from the load, set F1-37 (Auto-tuning selection) to 1

(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

F1, F2 (motor 1 parameters and encoder parameters) and group A2 (motor 2 parameters),

group A3 (motor 3 parameters) and group A4 (motor 4 parameters).

You can select the current effective motor parameter group by means of function code F0-

24 or DI terminals with functions 41 and 42. When the DI terminals with functions 41 and 42

become ON, they are privileged and the setting of F0-24 becomes invalid.
