6-2-3 Auto-tuning of Motor Parameters
2 Selection of motor rotation during auto-tuning
In the Auto-tuning Selection (H001), select whether the motor rotates during auto-tuning.
3 Auto-tuning
(1) After presetting of parameters, set the Auto-tuning Selection (H001) to 01 (Enabled:
No motor rotation) or 02 (Enabled: Motor rotation).
(2) Turn ON the RUN command.
Turning ON the RUN command starts automatic operation in the following
procedure.

Description
Motor does not
rotate (01)
Measures motor parameter values without rotating the motor. Use this setting if
you do not rotate the motor. Because the motor does not rotate, the Motor
Parameter Io (No-load current) and Motor Parameter J (Moment of inertia)
values cannot be measured.
Motor rotates (02)
Measures motor parameter values with the motor rotating. Use this setting if you
can rotate the motor without any problem.
