7 MOTION PROGRAMS FOR POSITIONING CONTROL
The following operation assumes that a skip (G32) is specified during constant-speed control
(G01) and the [degree] axis without a stroke range is included.
When an absolute value command exists after a skip under this condition, the last positioning
point and the travel distance in the whole program are the same independently of whether a skip
is executed or not. This is indicated by the following example.
(1) When the skip instruction is an incremental value command and subsequent instructions are
also incremental value commands
<Program example>
G91 ;
G32 X180. SKIP#X100 F10. ;
G01 X180. ;
G01 X270. ;
(2) When the skip instruction is an absolute value command and subsequent instructions are
also absolute value commands
<Program example>
G90 ;
G32 X180. SKIP#X100 F10. ;
G01 X350. ;
G01 X170. ;
(Note) : The above explanation is valid until a deceleration stop (constant-speed positioning
command to point-to-point positioning command, etc.) after skip (G32). After a
deceleration stop, operation of the normal [degree] axis is performed. The conditions of
deceleration stop after a skip (G32) are shown below. Refer to "7.13.19 G32 Skip" for
details.
1) When the point-to-point positioning command (G00, G25, G28, G30 or the like) is
executed after the G32 block.
2) When the high-speed oscillation stop (G26) is executed after the G32 block.
3) When the absolute value command (G90) or incremental value command (G91) is
executed after the G32 block.
4) When the block immediately after G32 is in the constant-speed positioning command
but its command axes do not include the specified axis of the G32 block.
CAUTION
<Motion without a skip>
0 180
<Motion with a skip>
(When a skip is made at 100 ( degree))
0 100
<Motion without a skip>

<Motion with a skip>

Even if a skip is not executed, the last
positioning point is the same.
