Using Siemens PLC Function Blocks: MC_Home and MC_Halt 

MC_Stop prevents any other MC function from executing while the enable input it active. MC_Halt only cancels (most) active moves and stops the axis. If the enable input stays enabled on a MC_Halt and another MC block is positively executed (such as MC_MovRelative) the axis will move again. This is a great point to bring up, because I use the MC_Halt function mainly to cancel moves such as positioning moves or gearing, but if you want to prevent the axis from moving you would need to use an MC_Stop

Hello Can I use mc-home when using mc-stop or mc-halt?

If you are running MC_Home both MC_Halt or MC_Stop to cancel the homing move.
