11.3.2 Motion Command Details
11-22
(3) Zero Point Return (ZRET)
When a ZRET command is executed, the zero point return will be completed immediately. Position information
will not be updated.
(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)

Motion Command
The zero point return operation starts when this parameter is set to 3. The
operation will be canceled if this parameter is set to 0 during ZRET command
execution.
OB
091
Command Abort
The zero point return operation will be canceled if this bit is set to 1 during
zero point return operation.
OB
095
Position Reference
Type
Switch the type of position reference.
0: Incremental addition mode, 1: Absolute mode
Set this parameter before setting the Motion Command Code (OW
