: You can set this parameter during operation
Motor Auto-tuning
Control Mode
FOCPM Default: 0
Settings 0: No function
1: Only for an unloaded motor; auto-measures the angle between magnetic pole
and PG origin (Pr.08-09)
2: Auto-tuning PM parameters (suggested to lock the brake)
3: Auto-measures the angle between magnetic pole and PG origin (Pr.08-09)
Position the elevator near the middle floors before auto-tuning.
Auto-tuning process: 2, and then 1 or 3.
Motor auto-tuning:
Set Pr.08-00 to 1 to 3, and then press the RUN key on the digital keypad KPC-CC01 (Pr.00-15=2) to start
auto-tuning. Or when the drive is in manual mode (inspection), run the upward operation or downward
operation (Pr.00-15=1) to start auto-tuning immediately. In the process of auto-tuning, an “Auto tuning”
warning continuously displays on the digital keypad until it is finished.
Pr.08-00=2: Motor auto-tuning is static test:
1. Make sure that all the drive parameters are set to defaults and the motor wiring is correct.
2. Enter the correct values for Pr.01-01, Pr.01-02, Pr.08-01, Pr.08-02, Pr.08-03 and Pr.08-04. Refer to
motor capacity to set the acceleration/deceleration time.
3. Note that the motor will run! The shaft needs to be locked by an external force.
4. After auto-tuning is finished, check if Pr.08-05, Pr.08-07, and Pr.08-08 all have values.
Pr.08-00=1: Auto-measures the angle between the magnetic pole and the PG origin. Pay attention to the
following notes when measuring: (dynamic test)
1. Unload before auto-tuning.
2. If the drive controls the brake, the drive can auto-tune according to the normal sequence after you
complete the wiring and set the brake control parameters.
3. If the host controller controls the brake, make sure that the brake is in release status before auto-
tuning.
Pr.08-00=3: Auto-measures the angle between the magnetic pole and the PG origin. Pay attention to the
following notes when measuring: (static test)
1. The motor can be loaded or unloaded before auto-tuning.
2. See the reference table for auto-tuning for Pr.10-00 (PG Signal Type).
3. If the drive controls the brake, the drive can auto-tune according to the normal sequence after you
complete the wiring and set the brake control parameters.
4. If the host controller controls the brake, make sure that the brake is in release status before auto-
tuning.
5. Make sure the setting for Pr.10-02 is correct. Incorrectly setting Pr.10-02 causes incorrect positioning
of the magnetic pole and results in the wrong angle between the magnetic pole and PG origin.
NOTE:
The entered rated speed cannot be larger than or equal to 120 f/p.
Note that if the contactor and brake are not controlled by the AC motor drive, release it manually.
