Danger of collision!
Enter in MP7441 bit 2 whether the TNC should output an
error message (bit 2=1) or not (bit 2=0) if a positive depth
is entered.
Keep in mind that the TNC reverses the calculation for pre-
positioning when a positive depth is entered. This
means that the tool moves at rapid traverse in the tool axis
to set-up clearance below the workpiece surface!
Enter in MP7441 bit 0 whether the TNC should output an
error message (bit 0=0) or not (bit 0=1) if spindle rotation
is not active when the cycle is called. The function also
needs to be adapted by your machine manufacturer.
If you call the cycle with machining operation 2 (only
finishing), then the TNC positions the tool to the first
plunging depth at rapid traverse!
