Function Code Parameter Name Setting Range Default Min. Unit
F1-16 Motor auto-tuning mode 0–4 0 1
Note
Motor auto-tuning can be performed only in the operation panel control mode (F0-02 = 0). Before
motor auto-tuning, set motor ratings (F1-00 to F1-05) and PPR of the encoder (F2-14) correctly.
If a PMSM is used, motor auto-tuning is mandatory in one of the following conditions:
•
Before rst-time running
•
When the motor/encoder is replaced
•
When wiring of the encoder is changed
PMSM running is prohibited before motor auto-tuning succeeds, because it may result in runaway. If
locked-rotor occurs, it indicates that motor auto-tuning fails.
The auto-tuning procedure is as follows:
1. After setting F1-16, press
ENTER
. Then "TUNE" is displayed and blinks.
2. Press the
OPEN
or
CLOSE
to start auto-tuning, and "TUNE" stops blinking. The auto-tuning
process can be stopped by pressing
STOP
RES
.
3. After the auto-tuning ends, the operation panel restores to the display at stop state. F1-16
resumes to 0 automatically.
The values of F1-16 are described as follows:
•
0: No auto-tuning
•
1: Static auto-tuning for asynchronous motor
It applies to the applications where complete auto-tuning cannot be performed because
the asynchronous motor must be connected with the load. The stator resistance, rotor
resistance and leakage inductance are obtained from auto-tuning. The magnetizing current
and mutual inductance can be calculated.
•
2: Complete auto-tuning for asynchronous motor
Complete auto-tuning is preferred to ensure dynamic control performance of the controller.
This mode requires the motor to be disconnected from the load.
The controller performs static auto-tuning first. Then according to the default system
setting, the controller accelerates to 80% of the rated motor frequency within 2s, keeps the
frequency for a certain period and then decelerates to zero speed within 2s.
•
3: No-load auto-tuning for PMSM
The following parameters are obtained by auto-tuning:
- F1-14 (Encoder zero position angle of PMSM)
- F1-06 (Stator phase resistance of PMSM)
- F1-11 (Shaft D inductance of PMSM)
