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.
