Operating Procedure (Motor rotates: H001 = 02)
* If the "motor does not rotate" (H001 = 01) is selected, steps (4) and (5) are not performed.
 The rotation frequency in step (5) is defined as follows, if "T" represents
the acceleration time or deceleration time in step (4), whichever is
larger:
0 s < T < 50 s: x = 40%
50 s ≤ T < 100 s: x = 20%
100 s ≤ T: x = 10%
Step 1: Set the motor
capacity and number of
poles according to the motor
ratings.
Step 2: Set the base
frequency and motor
voltage selection according
to the motor ratings.
Step 3: Set Auto-tuning
Selection (H001) to 02.
After the auto-tuning, the
result is displayed.
Starts the automatic
operation.
Step 4: Issue a RUN
command according to the
setting of RUN Command
Selection (A002).
Step 5: After the operation
is completed, use the
STOP/RESET key to cancel
the result display.
Issuing a RUN command starts automatic operation in the
following sequence:
(1) 1st AC excitation (The motor does not rotate.)
↓
(2) 2nd AC excitation (The motor does not rotate.)
↓
(3) 1st DC excitation (The motor does not rotate.)
↓
(4) V/f control operation (The motor rotates until 80% of the base
frequency.)
*
↓
(5) Sensorless vector control operation (The motor rotates until
x% of the base frequency.)
*
↓
(6) 2nd DC excitation (The motor does not rotate.)
↓
(7) The auto-tuning result is displayed.
Step 6: Reflect the
automatically measured
motor parameters in the
operation data.
