SINUMERIK 840D sl Operation/Programming ShopTurn (BAT) – 08/2005 Edition 4-131
Incremental dimension
(INC)
With incremental dimensions, also called sequential dimensions, a
position specification refers to the previously programmed point, i.e.
the input value corresponds to the traversed path. As a rule, the
preceding symbol plays no role during the inputting of the incremental
value. ShopTurn only evaluates the amount of the increment. For
some parameters, the preceding symbol specifies the traversing
direction. These exceptions are identified in the parameter table of the
individual functions.

Incremental dimensions
The positions for points P1 to P4 in incremental dimensions are as
follows:
P1: X25 Z-7.5 (relative to the zero-point)
P2: X15 Z-7.5 (relative to P1)
P3: Z-10 (relative to P2)
P4: X20 Z-10 (relative to P3)
