Set encoder
parameters
F1-00 Encoder type 0 2
0: SIN/COS encoder
1: UVW encoder
2: ABZ encoder
3: Endat absolute encoder
Set F1-00 according to the actual encoder type.
F1-12
Encoder pulses per

2048
Set this parameter according to the encoder nameplate.
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 1
4: Shaft auto-tuning 2
5: Synchronous motor static auto-tuning
After setting F1-11 to 1, 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 rectied
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.
Five parameters F1-14 to F1-18 are obtained.

After auto-tuning is completed, F0-01 must be restored to 1. Otherwise, the
elevator cannot run.
Pay attention to the following precautions during asynchronous motor auto-tuning:
The sequence of encoder phases A and B must be correct. If the sequence is incorrect, fault E38 is
reported. To solve the problem, exchange phases A and B of the encoder.
