3.6 Path calculation
3.6 Path calculation
The path calculation determines the distance to be travelled within a block, taking all offsets
and compensations into consideration.
The formula is generally as follows:
Path = setpoint - actual value + zero offset (ZO) + tool offset (TO).

If incremental position data input is used, the zero offset is incorporated normally in the first
block.
Path = incremental position data + ZO + TO
If a new zero offset and a new tool offset are programmed in a new program block, the formula
is as follows:
With absolute position data input
Path = absolute position data P2 - absolute position data P1 + ZOP2 - ZOP1 +TOP2 -
TOP1
With incremental position data input
Path = incremental position data + ZOP2 - ZOP1 +TOP2 - TOP1.
