H Precautions Before Auto-tuning
Caution Do
not connect a load to the motor when performing auto-tuning. Doing so may re
-
sult in personal injury or equipment damage.
• The
Inverter
’
s auto-tuning function automatically determines the motor parameters while a servo sys
-
tem’s auto-tuning function determines the size of a load, so these auto-tuning functions are funda-
mentally different.
• If
a load is connected when auto-tuning is performed, not only will incorrect motor parameters be re
-
corded, but the motor may operate erratically resulting in dangerous conditions such as loads
falling
from vertical axis motors. Never perform auto-tuning with a load connected to the motor.
H Required Parameter Settings
Enter auto-tuning mode and make the following parameter settings:
Rated Voltage: Set the rated voltage (VAC) shown on the motor’s nameplate.
Rated Current: Set the rated current (A) shown on the motor’s nameplate.
Rated Frequency: Set the rated frequency (Hz) shown on the motor’s nameplate.
Rated Speed: Set the rated speed (r/min) shown on the motor’s nameplate.
Number of poles: Set the number of poles.
Motor Selection: Select motor 1.
For two-motor switching control, select motor 1 or motor 2.
PG Pulses/Rev: Set the number of A-phase or B-phase pulses per revolution.
The following message will appear when the parameters have been set:
