ABSOLUTE or RELATIVE positioning mode
This data defines whether the program position should be interpreted as being absolute (as
coordinate point) or relative (as the distance to be moved).
 ABSOLUTE or RELATIVE for linear axis or rotary axis without modulo correction
– ABSOLUTE:
The axis moves to the specified position and references itself to the axis zero. The soft-
ware limit switch monitoring is effective.
– RELATIVE:
The axis moves around the specified position in the negative or positive direction and
references itself to the last position it approached.
The software limit switch monitoring is effective.
