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.
 Precautions
• Always try to perform Rotational Auto-Tuning as it gives more accurate results than Non-
Rotational Tuning/Terminal Resistance Tuning. Perform non-rotational tuning if the load
can not be disconnected (e. g. pump can not be disconnected from the motor).
• When using the same motor type in multiple installations but normally having it not avail-
able without load, perform an Auto-Tuning with an unloaded motor and then set the motor
data parameters (E1-/E2-) manually in the other installations.
• Motor contactors must be closed during the Auto-Tuning process.
• H1, H2 and HC signals must be ON when performing Auto-Tuning (keep wire link).
• Do not touch the motor until the Auto-Tuning process is complete. Voltage is applied to
the motor during the tuning process, even though the motor may not be rotating.
• To cancel Auto-Tuning, press the STOP key on the digital operator.
• During Auto-Tuning the motor is started and stopped repeatedly and may also rotate.
When the tuning is finished, "END" will appear on the operator panel. Do not touch the
motor until this display is shown and the motor has completely stopped.
 Teaching Function
Teaching function automatically sets up the data, needed by the drive to control the elevator
speed. Teaching is done in two steps:
