NOTICE: Never perform Rotational Auto-Tuning for a motor connected to a load. Failure to comply could result in improper drive operation.
If Rotational Auto-Tuning is performed for a motor coupled to a load, the motor parameters will be inaccurate and the motor may exhibit
abnormal operation. Disconnect or decouple the motor from the load.
Enter the required information from the motor nameplate. Press
to proceed to the Auto-Tuning start display.
Note:
These instructions continue from Step 7 in “Enter Data from the Motor Nameplate”.

Input Data for Auto-Tuning
The T1-

parameters are used to set the Auto-Tuning input data.
Note:
1.
Cycling power to the drive will reset any values set during the Auto-Tuning process to factory defaults.
2.
For motors that are to be operated in the field weakening range, first perform the Auto-Tuning with the base data, i.e. the frequency at
which the motor is operating with its rated voltage (base frequency). After Auto-Tuning is complete, change the maximum frequency
E1-04 to the desired value.
