6.2.4
Referencing and adjusting
Definitions
In order that the "SIMODRIVE 611 universal" drive precisely identifies
the machine zero point after power–on, the axis measuring system
must be synchronized with the machine.
This synchronization is realized when referencing incremental measur-
ing systems or adjusting absolute measuring systems.
Notice
The following functions are ineffective for axes which are either not
referenced not adjusted:

6.2.5
Referencing for incremental measuring systems
General
For axes with incremental measuring systems, each time the system is
information
powered–up, the position reference to the machine zero point must be
established.
Synchronization is realized for a reference point approach by accepting
a specific position value at a known point of the axis.

Before SW 4.1:
The encoder must be re–referenced if, for a referenced incremental
measuring system, a parameter set was changed over.
From SW 4.1:
Using P0239, the behavior for a parameter set changeover can be
set for a motor measuring system.
P0239 = 0: Behavior as before SW 4.1 (standard)
P0239 = 1: For a parameter set changeover, it is only necessary
to re–reference the encoder, if the ratio P0237/P0238
has changed.
