_M300 Boring CYCLE86
Adapt the spindle to the tool position (SD55216 $SCS_FUNCTION_MASK_DRILL_SET
bit 6 = 1)
For specific machine kinematics, it may be necessary to make an additional adjustment
of the correction angle for the spindle positioning (e.g. intermediate gear at the spindle).
The _M300 mark is run through after the correction angle is calculated. There the correc‐
tion angles _MEA_CORR_ANGLE[0] (for the manufacturer) and _MEA_CORR_AN‐
GLE[1] (system) can be changed, if applicable. For subsequent spindle positioning oper‐
ations, both angles act additively in CYCLE86.
21.3.6 CUST_MULTICHAN user cycle
Function
The CUST_MULTICHAN cycle is used for multi-channel programming at lathes. It is called at
the start of the block when programming with blocks.
In the cycle, e.g. the master spindle is set to the spindle specified at the start of the block. The
return value (= 1) can be used to control whether the complete block is skipped.
CUST_MULTICHAN
Parameter Meaning
_S_NR Spindle number to which the master spindle is set.
_RET
= 0
= 1
Return value
The block is executed corresponding to the run-in mode.
The entire block is skipped.
