Description of formal parameters
The table below shows all formal parameters of the "MCP_IFT" function:
Call example
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 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.
