Explanation of the formal parameters
The table below shows all formal parameters of the "MCP_IFT" function:
Signal
BAGNo
ChanNo
SpindleIFNo
FeedHold
SpindleHold
Call example
CALL FC 25 (
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.
