The actual position is set to 0 before each positioning. Thus the travel range has no
fixed zero point. All positionings are relative - in relation to the actual position.

Since the positioning mode (relative or absolute) can be selected additionally for
each positioning data record, mixed operation is possible too.
Execution of the positioning data records: sequential / single
positioning
With a START edge (X12/7=24VDC) after
!
Machine zero run or after the
!
"Deenergized state"
the selected positioning data record is executed.
!
On the next STARTedge the next positioning data record is executed
(irrespective of the set positioning data record address).
If the positioning data record address 0 is still present, the machine zero run is
executed.
!
With a repetition number >1 this can be the same positioning data record.
!
Subsequent STARTs execute the current positioning data record the number of
times corresponding to the repetition number.
!
The next start thereafter switches to the next positioning data record.
!
After the last positioning data record, the positioning data record 1 is executed
next.
!
(see on page 56 ) = 0 reads in the address new.
After a
STOP with termination
(see on page 58 ), the positioning address is read
in new.
After
STOP without termination
(see also on page 58 ) the sequential positioning
is interrupted; on the next START the sequential positioning is resumed with the
interrupted positioning data record.
