rotating the second motor (motor
other than the IPM motor MM-EFS/
MM-THE4).
11
Performs offline auto tuning without
rotating the motor (for IPM motor
MM-EFS/MM-THE4).

(The value measured by offline auto
tuning is automatically set.)
9999: Uses the MM-EFS/MM-THE4
constant for the IPM motor MM-EFS/
MM-THE4, and the inverter internal
data for a PM motor other than
MM-EFS/MM-THE4.
