Mark-related positioning [POSR]
100
8.4.11 Mark-related positioning [POSR]
Use this command to position e.g. a mark relative to an external signal.
POSR value
Value: two digits after the decimal point (three for inches) in unit corresp. to P90; a
control parameter (P40..P49) or a variable (V1..V39)
e.g. POSR .P40.
The prefix determines the direction in which the mark is approached.
Note!
POSR 0 is not permitted!
When the mark reference is activated, do not use the POSA command!
I14: Activating mark reference . I14 must be present before the command.
I16: Mark input The rising flank is evaluated (pulse > 0.6ms).
(is read in with a rating of 100 µ s; the max. error is therefore 100 µ s)
O16: With "0", the mark is missing after travel to the mark is completed (P38).
P35: ="1": Mark reference switched on;
="0": Mark reference switched off.
P37,P38: A mark window is specified relative to the start position using P37 and P38.
P37: Minimum travel to mark. (relative to start position).
Range of values for P37: 0.00 ... P38
P38: Maximum travel to mark. (relative to start position).
Range of values for P38: P37 ... 4 000 000
P39: Maximum feed length, if there is no mark in the mark window (relative to start
position).
Range of values for P39: P38 ... P11 or P12
POSR 100 P35="1"; P37=+300; P38=+600; P39=+800; I14="1".
If the mark is between +300 and +600, mark +100 is positioned, if the mark is
outside the window it is positioned to 800.

O16
It will go on "0" if no label
come until P38.
Note!
The drive positioning is not limited by P39.
If the mark is within the mark window, COMPAX executes positioning using the
POSR value for a value of the corresponding size, even after P39.
The process range can be limited using P11 and P12.
When the mark reference is switched on, the inputs I14, I15, and I16 are no
longer available for external data record selection (GOTOEXT,
GOSUBEXT).
