3.2.4 Positioning with absolute / incremental encoders in absolute mode
The encoder used for positioning is activated via parameter P604 "Encoder Type". Here, a differentiation is
made between normal measurement (for "linear" systems) and "path optimised" measurement (for circulating
systems).

Table 15: - P604 Selection of encoder type
In the function "Optimum Path" the multi-turn resolution of the encoder can be additionally limited for the
overflow point via parameter P615 "Maximum Position". The multiturn resolution in rotations (1 rotation =
1,000 rev) is entered in parameter P615. It is also possible to enter a non-integer value of rotations (for
example see Section 3.2.4.2).
After the setting or selection of the encoder type in parameter P604 "Distance measuring system" the function
of the encoder can be tested via parameter P601 "Actual Position".
