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:
