5.1 Function Code Setting
CAUTION
•
Set the function code
in the following order at first.
(1) C21 (2) P01 (3) F03 (4) L31 (5)P02
Because when you change them, some other function codes synchronize and change.
There is a risk of accident or injury.
Set the function code as follows before beginning magnetic pole position offset tuning.

5.2 Procedure of Magnetic Pole Position Offset Tuning
You have to execute the tuning as follows before driving motor.
Please inquire of the maker if tuning is impossible normally.
1. Tuning Mode (Function code L03)
Tuning mode is selected by function code L03 as follows. Usually, it is selected according to the tuning procedure.
1 : Tuning operation
2 : Tuning operation with wrong wiring detection (Er7 occurs if wrong wiring is detected.)
3 : Tuning operation with checking accuracy (Er7 occurs if tuning accuracy is not good.)
4 : Reserved for particular manufactures (Do not access this function code.)
5 : Reserved for particular manufactures (Do not access this function code.)
2. Tuning Condition
The recommended condition is following.
(1) The rotor is fixed.
If it is impossible to fix the rotor, it is acceptable even if the rotor is free. (In this case, if the torque bias has been
set, cancel it.)
(2) Encoder abnormality detection is effective. (It is effective in the initial condition as follows. L90=1, L91=10%,
L92=0.5)
