Request function
Do not request function
• If more than 1 function is activated, then the following applies:
The values for all functions cannot be read until each activated function has
terminated and this has been confirmed in the corresponding status bit
(ZSW.0/.1/.2/.3 "0" signal again).
• Reference mark search
It is possible to search for a reference mark.
• External zero mark
• Flying measuring
Positive and negative edges can be simultaneously selected.
