Synchronous motor no-load auto-tuning (motor disconnected from car)
Enter the emergency electric RUN state
Set motor type: F1-25 = 1
The brake must be released manually in no-load auto-tuning state.
After auto-tuning is completed, the controller stops output automatically.
Set encoder parameters: F1-00 and
F1-12
Set motor parameters: F1-01 to F1-05
Check F0-01 = 0
F1-11 = 2
Perform auto-tuning:
① Release the brake manually.
② Press the RUN key on the operation
panel to start auto-tuning.
X9 indicator on the MCB is OFF, indicating that the elevator enters the emergency
electric RUN state.
Set F1-25 to 1.
① Obtain the rated motor power, rated motor voltage, rated motor current, rated
motor frequency, and rated motor speed from the motor nameplate.
② Be sure that motor parameters are set correctly. Otherwise, faults will occur.
① Set F1-00 according to the actual encoder type.
0: SIN/COS encoder; 1: UVW Encoder; 2: ABZ Encoder; 3: Endat encoder
② Set F1-12 (Encoder pulses per revolution) according to the encoder nameplate.
F0-01 must be set to 0 during no-load auto-tuning.
After setting F1-11 to 2, press ENTER. If the operation panel displays "TUNE", the
system enters the 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 in emergency electric RUN state.
② Whether the MCB displays faults to be rectified.
③ Whether F0-01 is set to 0.
Auto-tuning completed
① After auto-tuning is successful, the MCB displays the learnt encoder angle for 3s.
If auto-tuning fails, the MCB displays Err.
② Ensure that the value deviation of F1-06 is within ±5° through multiple times of
auto-tuning.
③ F1-08 is mostly set to 0 or 8. F1-08 remains unchanged through multiple times of
auto-tuning.
Restore F0-01 to 1
After auto-tuning is completed, F0-01 must be restored to 1. Otherwise, the
elevator cannot run.
󶙽Synchronous motor no-load auto-tuning
Pay attention to the following precautions during synchronous motor auto-tuning:
■
Synchronous motor auto-tuning learns motor initial pole angle, encoder initial
angle, motor wiring mode, and shaft-D and shaft-Q inductance.
■
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° .
■
Each time the encoder, encoder cable connection or motor wiring sequence as
well as rated motor current, frequency and speed is changed, perform motor auto-
tuning again.

Therefore, when you replace the MCB, you can directly run the controller by
manually setting F1-06 to the original value rather than performing motor auto-
tuning
