Control
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
plate data to be entered depends on the selected type of Auto-Tuning. This example shows Rotational Auto-Tuning.

If Auto-Tuning can not be performed for some reason (no-load operation impossible etc.), then set up the maximum
frequency and voltage in the E1- parameters and enter the motor data manually into the E2- parameters.
NOTICE: The Safe Disable inputs must be closed during Auto-Tuning.

Application Conditions and Benefits
• Motor and load can not be decoupled and the load is
higher than 30%.
• A motor test report listing motor data is not available.
• Automatically calculates motor parameters needed for
vector control.
• Motor and load can not be decoupled and the load is
higher than 30%.
• A motor test report is available. Once the no-load current
and the rated slip have been entered, the drive calculates
and sets all other motor-related parameters.
• The drive is used in V/f Control and other Auto-Tuning
selections not possible.
• Drive and motor capacities differ.
• Tunes the drive after the cable between the drive and
motor has been replaced with a cable over 50 m long.
Assumes Auto-Tuning has already been performed.
• Should not be used for any vector control modes unless
the motor cable has changed.
• Recommended for applications using Speed Estimation
Speed Search or using the Energy Saving function in V/f
Control.
• Assumes motor can rotate while Auto-Tuning is
executed. Increases accuracy for certain functions like
torque compensation, slip compensation, Energy Saving,
and Speed Search.
