Initiation signal
"5 to 8" = Position axes
Positioning mode 0, 1, 2, 3, 4
Number of machine axis
Position
Positioning speed; if FRate = 0, the value is taken from machine data
POS_AX_VELO (unit as set in machine data).
Is set to "1" when position is reached with "Exact stop fine".
With positioning error = "1"
