Call example
CALL FC24(
With these parameter settings, the signals are sent to the first mode group, the first channel
and all axes. In addition, the spindle override is transferred in the 4th axis/spindle interface.
The feed hold signal is passed to bit memory 22.0 and the spindle stop signal to data block
DB2, data bit 151.0. The spindle direction feedback signal supplied via parameter "SpindleDir"
can be used as a direction input for an additional FC18 call.
