01 Motor Parameters This parameter can be set during operation.

Motor Auto Tuning (PM)

Control mode

FOCPM

Factory setting: 0

Settings

0: No function

1: Auto-tuning for PM motor parameters (brake locked)

2: Auto-tuning for PG offset angle without load (Pr.01.09)

3: Auto-tuning for PG offset angle with load (Pr.01.09)

 When Pr.01-00 = 2, auto-tune for PG offset angle. Please follow the following 3 rules:

1. Unload before Auto-tuning begins.

2. If the brake is control by AC motor drive, the drive can complete tuning process after wiring

and brake control parameters are set.

3. If the brake is control by host controller, maker sure brake is at release status when tuning.

 When Pr.01-00=3, auto-tuning for PG offset angle. Please follow the following 3 rules:

1. Tuning with load or unload are both allow.

2. When the brake is control by the AC motor drive, after wiring and braking parameters are

set up, the drive will execute Tuning following the settings.

3. When the brake is control by the host controller, make sure the brake is released before

execute Tuning.

4. Make sure Pr.03-02 (Encoder Input Type) is correct; a wrong setting would cause Pr.01-09

(PG offset angle) measurement error.

 When Pr.01-00=1, begins auto-tuning for PM motor by press the【Run】key. After auto-tuning process is

completed, the measured value will automatically be written into Pr. 01.05, Pr.01.07 (Rs、Lq) and

Pr.01.08 (Back EMF).

 AUTO-Tuning Process (static rolling) :

1. Make sure the drive is properly installed and all parameter settings are set to the factory

setting.

2. Motor: input accurate motor value into Pr.01.01, 01.02, 01.03, 01.04 and adjust the accel.

/decel. time according to your motor capacity.

3. Set Pr.01-00=1 and press the “RUN” key on the digital keypad. The motor should now

begin auto-tuning. (Note: It is important to fix the motor stably to prevent shaking.)

4. When auto-tuning is complete, check if measured values are written into Pr.01.05 and

01.07.

NOTE

; The input rated speed can not be greater than or equal to 120f/p.

; When auto-tuning is in process, an “Auto-tuning” message will show on the digital keypad. Once the process is complete,

the “Auto-tuning” message will be cleared and the measured values will be written into Pr.01-09.

; When auto-tuning is in process, if an error occurs or the drive is stopped manually, an “Auto Tuning Err” message will

appear on the digital keypad and it indicates auto-tuning failure, please check if the wirings of the drive are proper. When

“PG Fbk Error” occurs, please reset Pr.03-02 (if it is originally set to 1, change it to 2). When “PG Fbk Loss” occurs, please

check if the Z phase pulse feedback is normal.
