Auto-Tuning automatically sets up the motor data relevant drive parameters.
Type
Stationary Auto-Tuning for

Do not touch the motor until the Auto-Tuning is finished.
Failure to comply may result in minor or moderate injury. Voltage is still applied to the motor during the tuning
process, even thought the motor may not be rotating.
For Auto-Tuning enter the Auto-Tuning menu and perform the steps shown in the figure below. The number of name
