Operating modes
Operating mode: Absolute mode or continuous mode
A fixed measuring system is associated with the travel range: A fixed defined zero
point exists. All positions are referred to this zero point.
-100
-200

+100

+300
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 motion data record, mixed operation is possible too.
Execution of the positioning data records: Sequential or single
positioning
With a START edge (X12/7=24VDC) after
Homing 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 repeat count >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.
With
repetition number
(see page 101) = 0 the address is read in anew.
After a
STOP with interruption
(see page 99) the position set address is read in
anew.
After
STOP without interruption
(see page 99)the sequential positioning is
interrupted; on the next START the sequential positioning is resumed with the
interrupted positioning data record.
