Description of the formal parameters
The table below shows all formal parameters of the "MCP_IFM2" function:
Signal
BAGNo
ChanNo
SpindleIFNo
FeedHold
SpindleHold
SpindleDir
Call example
CALL FC 24 (
With these parameter settings, the signals are sent to the 1st mode group, the 1st channel
and all axes. In addition, the spindle override is transferred to 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 FC 18 call.
