8.6 PROGRAMMABLE SWITCHING OF DIAMETER/RADIUS
SPECIFICATION
Assume that diameter or radius specification has been selected for each
controlled axis by using bit 3 (DIA) of parameter No. 1006.
This function allows the use of a G code to switch between diameter
specification and radius specification for programmed axis commands
only.
When bit 5 (PDC) of parameter No. 1001 is set, the G code can be used
to specify whether programmed axis commands are to be specified in
diameters or radii.
Format
G10.9 IP_ ;
IP : Axis address for which switching between diameter
specification and radius specification is performed. IP
is followed by one of the following values:
0 : Radius specification
1 : Diameter specification
Specifying G10.9 rewrites bit 3 (PDA) of parameter No. 1009.
