Set datum
shift 8 Click the symbol.
There are two types of datum shift:
1. EnDat-compliant datum shift
This type considers the relation of datum and signal period (incremental signal).
Note
After the datum shift the absolute datum will not always be exactly the current position.
The ATS program calculates the new datum such that in relation to the incremental signals
its position corresponds to the EnDat specification, i.e. is as close as possible to the desired
position.
Attention
For encoder types "with incremental signals" (interface names EnDat 01 and EnDat 02)
the setting "EnDat-compliant datum shift" must be active.
If you want to repeat (e.g. correct) the datum shift, the current datum shift must be canceled
first!
Note
The checkmark at "Datum shift EnDat-conform" may only be removed for purely serial data
transmission.
