B-63530EN/03 4.DESCRIPTION OF PARAMETERS
- 321 -
3OF If the commands of three-dimensional coordinate conversion and tool
length compensation are not nested, an alarm is:
0 : Not raised.
1 : Raised. (P/S049 alarm)
[Example 1] An alarm is raised in the following cases:
<1> G68 X__ Y__ Z__ I0 J1 K0 R50.;
G43 H1 ;
G69 ;
G49 ;
<2> G43 H1 ;
G68 X__ Y__ Z__ I0 J1 K0 R50.;
G49 (or G43 H2, etc.);
G69 ;
←
P/S049 raised
←
P/S049 raised
[Example 2] No alarm is raised in the following cases:
<3> G68 X__ Y__ Z__ I0 J1 K0 R50.;
:
G43 H1 ;
:
G49 ;
:
G69 ;
<4> G43 H1 ;
:
G68 X__ Y__ Z__ I0 J1 K0 R50.;
:
G69 ;
:
G49 ;
NOTE
To program as in <4> of [Example 2] above, set
both bit 2 (D3R) of parameter No. 5400 and bit 6
(LVK) of parameter No. 5003 to 1, so that
three-dimensional coordinate conversion and tool
length compensation are not cancelled by a reset.
(If a reset is made in the middle of a program, the
direction of tool length compensation will be
affected.)
As shown below, a command to cancel tool length
compensation (G28, etc.) will not cause an alarm to
be raised. If a command like this is specified in the
G68 mode, program as indicated in <3> above.
