Set auto-tuning mode F1-11 Auto-tuning mode 0 2
0: No operation
1: With-load auto-tuning
2: No-load auto-tuning
3: Shaft auto-tuning
After setting F1-11 to 2, press
on the operation panel. If the
operation panel displays "TUNE", the system enters motor auto-tuning
state.
If the operation panel displays "F1-12", the system fails to enter motor
auto-tuning state.
You need to check:
1. Whether the elevator is inspection state.
2. Whether the MCB displays faults to be rectied
3. Whether F0-01 is set to 0
Perform auto-tuning 1. Release the brake manually.
2. Press
on the operation panel to start auto-tuning.
After auto-tuning is completed, the controller stops output automatically.
Auto-tuning completed 1. After auto-tuning is completed, the keypad on the MCB displays the
learnt encoder angle for 3s.
2. Ensure that the value deviation of F1-06 is within ±5° through multiple
times of auto-tuning.
Restore F0-01 to 1 F0-01 Command source selection 1 1
After auto-tuning is completed, F0-01 must be restored to 1. Otherwise, the
elevator cannot run.
Pay attention to the following precautions during synchronous motor auto-tuning:
a. Synchronous motor auto-tuning learns encoder initial angle, motor wiring mode, stator
resistance, shaft-D and shaft-Q inductance, and motor back EMF.
b. Perform three or more times of auto-tuning; compare the obtained values of F1-06 (Encoder
initial angle), and the value deviation of F1-06 shall be within ±5°.
c. Each time the encoder, encoder cable connection or motor wiring sequence is changed,
perform motor auto-tuning again.
d. You can modify F1-06 manually. The modication, however, takes effect only after power-
on again. Therefore, after you replace the MCB, you can directly set F1-06 to the original value
rather than performing motor auto-tuning; then, the controller can start to run after power-off
and power on again.
