Start: Initiation signal
Funct: "4" = Indexing axis
Note
With Funct: "4" = Indexing axis
The modulo conversion can be compared with approaching the indexing position via
POS[AX] = CIC (value) in the part program.
Mode: Positioning mode 0, 1, 2, 3, 4
AxisNo: Number of machine axis
Pos: Indexing position
FRate: Positioning speed; if FRate = 0,
the value is taken from machine data POS_AX_VELO
(unit as set in machine data).
InPos: Is set to "1" when position is reached with "Exact stop fine".
Error : With positioning error = "1"
State : Error code
