5.3.1 Identification of reference point position
When the frequency inverter is switched on during commissioning, the current position of the spindle
is identified by a search mode. The search mode continues for three revolutions at the set frequency
Reference Profile Frequency 809. As soon as the reference signal was recognized twice, the drive is
positioned to the
Reference orientation 469.

If the motor has already turned before release of axle positioning, the frequency inverter knows the
position of the reference point. In this case, positioning is carried out based on the
Reference orienta-
tion
469 without search mode.
5.3.2 Definition of sense of rotation for axle positioning
