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.

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.
The following message will appear when the parameters have been set:
Tuning Ready ?
Press RUN key
At this point, it is still possible to change the parameter settings by pressing the Increment and Decre-
ment Keys to display the desired parameter.
Press the Menu Key to cancel auto-tuning. (The operation mode display will appear.)

Performing Auto-tuning
Auto-tuning will start if the Run Key is pressed when the “Tuning Ready?” message is being displayed.
The motor will operate during auto-tuning, so be sure that it is safe for the motor to operate before press-
ing the Run Key.
The following message will be displayed when the Run Key is pressed:
Tune Proceeding
HZ A
Auto-tuning takes up to 1.5 minutes. The message “Tune Successful” will be displayed when auto-tun-
ing is completed. If auto-tuning has been completed successfully, press the Menu Key and proceed to
the next operation. If a fault occurred during auto-tuning, refer to
5-2-2 Auto-tuning Faults for details on
correcting the cause of the fault and perform auto-tuning again.
Note To cancel auto-tuning after it has been started, press the Stop Key to stop the operation and then
press the Menu Key to return to Drive Mode.
5-2-2 Auto-tuning Faults
One of the fault messages in the following table will be displayed if a fault occurs during auto-tuning. In
this case, determine the cause of the fault, correct it, and perform auto-tuning again.
