COORDINATE SYSTEM
3.1 Programming in millimeters (G71) or in inches (G70)
The displacements and feedrates of the axes may be defined in millimeters or in inches. The
unit system may be selected by program using the following functions:
G70 Programming in inches.
G71 Programming in millimeters.
Both functions may be programmed anywhere in the program; they do not have to go alone
in the block.
Operation
After executing one of these functions, the CNC assumes that unit system for the following
blocks. If none of these functions is programmed, the CNC uses the unit system set by
machine manufacturer [G.M.P. "INCHES"].
When changing the unit system, the CNC converts the currently active feedrate into the new
unit system.
Properties of the functions
The G70 and G71 functions are modal and are incompatible.
On power-up, after an M02 or M30 and after an EMERGENCY or a RESET, the CNC
assumes function G70 or G71 as set by the machine manufacturer [G.M.P. "INCHES"].
