Programming relative offset limits

Release Note

As of Build V2.11.2010.02, the command #MANUAL LIMITS [...] replaces the command #SET OFFSET [...]. For compatibility reasons, this command is still available but it recommended not to use it in new NC programs.

Syntax:

#MANUAL LIMITS [ AX=<axis_name> | AXNR=.. NEGATIVE=.. POSITIVE=.. ]

AX=<axis_name>	Name of axis for which the offset limits are valid.
AXNR=..	Logical number of axis for which the offset limit is to be valid, Positive integer
NEGATIVE=..	Negative relative offset value. Must be programmed as <0 in [mm, inch]
POSITIVE=..	Positive relative offset value. Must be programmed as <0 in [mm, inch]

This command defines the positive and negative limits for the permissible relative path motion in G201/G202 manual mode for each path axis. The relative negative and positive offset limits refer here to the starting point when manual mode was selected. Offset limits are also considered in G200 by setting the parameter P-CHAN-00114.

Notice

Relative offset limits can be overwritten at any time in the NC program. A sign check is made. Relative offset limits apply to each axis in the programming coordinate system (PCS).
