NOTE
;
In torque/vector control mode, it is not recommended to have motors run in parallel.
;
It is not recommended to use torque/vector control mode if motor rated power exceeds
the rated power of the AC motor drive.
;
When auto-tuning 2 motors, it needs to set multi-function input terminals (setting 14) or
change Pr.05-22 for motor 1/motor 2 selection.
;
The no-load current is usually 20~50% X rated current.
;
The rated speed can not be greater than or equal to 120f/p (f = rated frequency
Pr.01-01/01-35; P: number of motor poles Pr.05-04/05-16).
Permanent Magnet Motor (PM)
Set Pr.05-00= 5 or 13 and press [Run] to begin auto tuning for PM motor. The
measured values will be written into Pr.05-39(Rs), Pr.05-40 & 41(Ld & Lq)and
Pr.05-43(PM motor’s Ke parameter).
To begin AUTO-Tuning for PM motor in rolling test:
1. Make sure all the parameters are reset to factory setting and the motor wiring installtion is
correct.
2. For PM motor, set Pr.05-33=1 and complete the following settings according to your motor
specifications, Pr.05-34 rated current, Pr.05-35 rated power, Pr.05-36 rated speed and Pr.
05-37 pole number. The acceleration time and deceleration time should be set according to
your motor capacity.
3. Set Pr.05-00 to 5 and press [Run] to begin auto tuning for PM motor. Please be aware of the
motor that it starts spinning as [Run] is pressed.
4. When auto-tuning is completed, please check if the measured values are written into
Pr.05-39~05-41 and Pr.05-43 automatically.
Set Pr.05-00=4 and press [Run] to begin auto-tuning for PM motor PG offset angle. The
measured value will be written into Pr.05-42 automatically.
;
Note 1: When execute auto-tuning for PM motor PG origin, please make sure the
encoder setting are correct (Pr.10-00, 10-01, 10-02), otherwise the PG origin measure
error and motor stall may occur.
;
Note 2: If PM motor runs in an opposite direction of the drive’s command, switch any
two of the UVW cable and re-connect, then execute PG origin search again. It is crucial
to execute auto-tuning after the switch otherwise PG origin measure error and motor
stall may occur.
Auto-tuning process for measuring PG offset angle of PM motor:
1. Set Pr.05-00=5 and press RUN, or manually input the values into Pr. 01-01, 05-34~-541 and
Pr.05-43.
2. It is strongly suggested to remove the motor and unload before beings auto-tuning.
