11: Synchronous motor with-load auto-tuning

It is applicable to scenarios where the synchronous motor cannot be disconnected from

the load. During with-load auto-tuning, the motor rotates at the speed of 10 PRM.

Before performing with-load auto-tuning, properly set the motor type and motor

nameplate parameters of P1-00 to P1-05 frst.

By with-load auto-tuning, the AC drive obtains the initial position angle of the

synchronous motor, which is a necessary prerequisite of the motor's normal running.

Before the first use of the synchronous motor after installation, motor auto-tuning must

be performed.

Set this parameter to 11, and press

12: Synchronous motor no-load auto-tuning

If the synchronous motor can be disconnected from the load, no-load auto-tuning is

recommended, which will achieve better running performance compared with with-load

auto-tuning.

During the process of no-load auto-tuning, the AC drive performs with-load auto-tuning

first and then accelerates to 80% of the rated motor frequency within the acceleration

time set in P0-17. The AC drive keeps running for a certain period and then decelerates

to stop within the deceleration time set in P0-18.

Before performing no-load auto-tuning, properly set the motor type, motor nameplate

parameters of P1-00 to P1-05, "Encoder type" (P1-28) and "Encoder pulses per

revolution" (P1-27) and "Number of pole pairs of resolver" (P1-34) frst.

The AC drive will obtain motor parameters of F1-16 to F1-20, encoder related

parameters of P1-30 to P1-33 and vector control current loop PI parameters of P2-13 to

P2-16 by no-load auto-tuning.

Set this parameter to 12, and press

Motor auto-tuning can be performed only in operation panel mode.
