In this velocity range, the drive accelerates to the search velocity v1. The drive traverses to the
1
target position if the zero mark is recognized.
In this velocity range (search velocity), the drive traverses without changing its velocity until
2
the zero mark has been recognized. The drive then traverses to the target position.
In this velocity range, the drive brakes to the search velocity v2. The drive traverses to the target
3
position if the zero mark is recognized.
Condition: The maximum velocity P0102 must be greater than v2.

Procedure to shift the zero mark and set it to a specific value:
1. possibility:
– Enter the zero mark offset directly into P0128.
2. possibility:
– Traverse the spindle to the required position, e.g. manually rotate
– Set P0127 to 1. This means that the actual position value is
transferred into P0128. P0127 automatically changes to 0.
