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.
CAUTION
1 After IP, specify a value without a decimal point.
2 The block in which G10.9 is specified must not contain
any other command.
3 Parameters and offsets must be set according to the
setting of bit 3 (DIA) of parameter No. 1006.
4 Positions are indicated according to the setting of bit 3
(PDA) of parameter No. 1009.
5 When G10.9 is specified during parallel axis control,
the setting of bit 3 (PDA) of parameter No. 1009 for
the master and slave axes is changed regardless of
the parallel axis parking on/off state.
6 G10.9 is ignored during background graphic display.
7 The scale indication on the graphic screen is
displayed according to the setting of bit 3 (DIA) of
parameter No. 1006.
8 Axis movements by manual numeric commands G00
and G01 are made according to the setting of bit 3
(PDA) of parameter No. 1009.
9 The current positions and workpiece coordinate preset
values are set according to the setting of bit 3 (PDA)
of parameter No. 1009.
