5.5 SIMODRIVE POSMO A functions
5.5.1 Referencing
For SIMODRIVE POSMO A, an incremental position measuring
system is used. In order that the positioning motor identifies the axis
zero, the measuring system must be synchronized with the axis.
Table 5-7 What are the referencing possibilities?

Referencing possibilities Sketch
Approach the visual mark
Set the actual value by writing into P40
––> This position is assigned to the required
actual value.

Reference to occurring zero mark (from SW 2.1) Refer to Chapter 5.5.1
Flying ”Flying actual value setting” function
(from SW 1.4)
Refer to Chapter 5.5.2
1) The actual position to be written is corrected by the distance which was traveled since the last zero mark.
2) This function must be emulated using the existing traversing blocks (refer to the following examples).
