V variables
The CNC PILOT uses value ranges to define the scope of variables:
„ Real: V1 to V199
„ Integer: V200 to V299
„ Reserved: V300 to V900
The PLC program reads and describes the variables V1..V299.
#520 Depending on the tool type:
„ 1**, 2**: Tool tip radius (rs)
„ 3**, 4**: Shank diameter (d1)
„ 51*, 52*: Cutter diameter in front (df)
„ 56*, 6**: Cutter diameter (d1)
#521 Depending on the tool type:
„ 11*, 12*: Shaft diameter (sd)
„ 14*, 15*, 16*, 2**: Cutting width (sb)
„ 3**, 4**: Length of first cut (al)
„ 5**, 6**: Milling width (fb)
#522 Tool orientation (reference: machining direction of
tool):
„ 0: On the contour
„ 1: To the right of the contour
„ – 1: To the left of the contour
#523..#524 Set-up dimensions (ze, xe, ye)
#526..#527 Position of tool tip center I, K (see illustration)
#780 Tool from the database
Precondition for tool information: A tool call must be
programmed for the variables to become effective.

Read/write machine dimensions (MP 7):
Syntax: V{Mx[y]}
„ x = Dimension 1 to 9 (10 to 99 only for machine tool
builders)
„ y = coordinate: X, Y, Z, U, V, W, A, B or C
Read/write tool compensation:
Syntax: V{Dx[y]}
„ x = T number
„ y = length compensation: X, Y, or Z
