(8) Zero Point Setting (ZSET)
The ZSET command sets the current position as the zero point of the machine coordinate system.
(a) Operating Procedure
Note: The following position information is updated when command execution is completed.
• Machine Coordinate Target Position (TPOS) (IL
OE) = Zero Point Offset (ABSOFF) (OL
48)
• Target Position (CPOS) (IL
10) = Zero Point Offset (ABSOFF) (OL
48)
• Machine Coordinate System Position (MPOS) (IL
12) = Zero Point Offset (ABSOFF) (OL
48)
• Machine Coordinate Feedback Position (APOS) (IL
16) = Zero Point Offset (ABSOFF) (OL
48)
