Table 9- 19 DDS changeover response
DDS Changeover response
0 -
1 Switchover during pulse inhibit or operation has no effect
2 Pulse inhibit: Position actual value processing is reinitiated
Operation: Fault is output. Position actual value processing is reinitiated
3 - 6 Pulse inhibit: Position actual value processing is reinitiated
Operation: Fault is output. Actual position value processing is re-initiated
7 MDS changeover alone during pulse inhibit or operation has no effect
"Is reinitiated" means: For absolute encoders, the absolute value is read out anew and for incremental encoders a
1)
restart is performed just like after a POWER ON.
For incremental encoders r2684.11 ("Reference point set") is reset, and additionally for absolute encoders the status of
2)
adjustment (p2507).
For incremental encoders r2684.11 ("Reference point set") is reset, and for absolute encoders the status of adjustment
3)
(p2507) is not additionally reset, as the encoder data set is different from the original.
