Traversal per part program

Three geometry axes AX1, AX2 and AX3 exist in a machine. For geometry axis AX1, the
part program-driven total traverse path, total travel time and travel count should be
calculated.
Parameterization
Activation of the overall function:
MD18860 $MN_MM_MAINTENANCE_MON = TRUE
Group activation: "total traverse path, total travel time and travel count" for geometry axis
AX1:
MD33060 $MA_MAINTENANCE_DATA[AX1] = 1
Part program
For values calculation based on the part program, the current value of the system variables
at the beginning of the part program must be saved as calculational variables. The difference
is acquired at the end of the part program.
Part program (extract)
Programming
. . .
R10 = $AA_TRAVEL_DIST[ AX1 ]
R11 = $AA_TRAVEL_TIME[ AX1 ]
R12 = $AA_TRAVEL_NR[ AX1 ]
. . .
R10 = R10 - $AA_TRAVEL_DIST[ AX1 ]
R11 = R11 - $AA_TRAVEL_TIME[ AX1 ]
R12 = R12 - $AA_TRAVEL_NR[ AX1 ]
