Once the function is complete (position determined for reference mark or measurement
probe), r2526.1 (reference function active) and r2526.2 (measurement valid) continue to
remain active and the measurement is provided by r2523 until the corresponding input
p2508 or p2509 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.
If both binector inputs p2508 and p2509 are simultaneously set, this causes the active
function to be interrupted and no function is started. This is indicated using alarm A07495
"reference function interrupted" and remains until the signals at the binector inputs are reset.
The alarm is also generated if, during an activated function (reference mark search or
measuring probe evaluation) a fault is signaled using the encoder status word.
If the "position control" 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.
