With preset absolute dimensions (G90), the IC command can be used to set non-modal
incremental dimensions for individual axes.
Note
Non-modal incremental dimensions (IC) are also possible for spindle positioning
(SPOS, SPOSA) and interpolation parameters (I, J, K).
Syntax
G91
<axis>=IC(<value>)
Meaning
G91: Command for the activation of modal incremental dimensions
IC: Command for the activation of non-modal incremental dimensions
<axis>: Axis identifier of the axis to be traversed
<value>: Position setpoint of the axis to be traversed in incremental dimensions
G91 extension
For certain applications, such as scratching, it is necessary that only the programmed distance
is traversed in incremental dimensions. The active zero offset or tool length offset is not
traversed.
This behavior can be set separately for the active zero offset and tool length offset via the
following setting data:
SD42440 $SC_FRAME_OFFSET_INCR_PROG (zero offsets in frames)
SD42442 $SC_TOOL_OFFSET_INCR_PROG (tool length offsets)
Value Meaning
0 With incremental programming (incremental dimensions) of an axis, the zero offset or the tool
length offset is not traversed.
1 With incremental programming (incremental dimensions) of an axis, the zero offset or the tool
length offset is traversed.
