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.

Note 1 Steps 4 and 5 will be skipped in auto-tuning without motor rotation (H001 = 01).
2 The motor speed X in step 5 is given as follows, where T is the acceleration or deceleration time in step 4,
whichever is greater.
T ≤ 0 < 50 s:
0 s ≤ T ≤ 100 s: X = 20%
100 s ≤ T:
6 - 20
Description
The motor does not rotate during auto-tuning.
The motor rotates during auto-tuning.
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.
Measures motor parameter values with the motor rotating. Use this
setting if you can rotate the motor without any problem.
