2 Auto-tuning
(1) Set the Auto-tuning Selection (H001) to 01 (Enabled: No motor rotation).
The available setting for PM motor auto-tuning is 01 (Enabled: No motor rotation) only. The
setting “02 (Enabled: Motor rotation)” is not displayed.

(2) Turn ON the RUN command based on the setting in the 1st RUN Command Selection
(A002).
Turing ON the RUN command causes the inverter to start automatic operation, during
which auto-tuning is executed in the following sequence.
If auto-tuning is completed successfully, the auto-tuning result will be set to the parameters
H111 to H113.
1) Initial pole position estimation (Motor does not rotate.)
