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.
