Set this parameter to 2, and press
. Then, the AC drive starts complete auto-
tuning.
• 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 F1-00 to F1-05 rst.
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 rst use of the synchronous motor after installation, motor auto-tuning must
be performed.
Set this parameter to 11, and press
. Then, the AC drive starts with-load auto-tuning.
• 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
rst and then accelerates to 80% of the rated motor frequency within the acceleration
time set in F0-17. The AC drive keeps running for a certain period and then decelerates
to stop within the deceleration time set in F0-18.
Before performing no-load auto-tuning, properly set the motor type, motor nameplate
parameters of F1-00 to F1-05, "Encoder type" (F1-28) and "Encoder pulses per
revolution" (F1-27) and "Number of pole pairs of resolver" (F1-34) rst.
The AC drive will obtain motor parameters of F1-16 to F1-20, encoder related
parameters of F1-30 to F1-33 and vector control current loop PI parameters of F2-13 to
F2-16 by no-load auto-tuning.
Set this parameter to 12, and press
. Then, the AC drive starts no-load auto-
tuning.
Motor auto-tuning can be performed only in operation panel mode.
Group F2: Vector Control Parameters
Group F2 is valid for vector control, and invalid for V/F control.
