Siemens SINAMICS S150 Operating Instructions Manual page 363

corresponding input p2508 (activate reference mark searches) or p2509 (activate
measurement probe evaluation) is reset (0 signal).
If the function (reference mark search or measuring probe evaluation) has still not been
completed and the corresponding input p2508 or p2509 is reset, then the function is
interrupted via the encoder control word and status bit r2526.1 (reference function active) is
reset via the encoder status word.
Setting the two binector inputs p2508 and p2509 at the same time results in the active
function being aborted and/or no functions being started. This is indicated by alarm A07495
"reference function aborted" and remains active until the activations at the binector inputs
are reset. The alarm is also generated if a fault is signaled during an activated function
(reference mark search or measurement probe evaluation) by the encoder status word.
If the "position controller" function module is selected, these parameters (p2508 to p2511)
are preassigned with "0". If the "basic positioner" function module is selected, the "reference
mark search" (for search for reference point) and "measurement probe evaluation" (for the
flying referencing function) functions are initiated by the "basic positioner" function module
and feedback (r2526, r2523) returned to this.
