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 the T1-07 (Motor Base Speed), set during the Auto-Tuning
process to factory defaults.
2. For motors that are to be operated in the eld weakening range, rst 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.
