Input Data for Auto-Tuning

The T1-oo 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.
