3.13.9 Tool length compensation for orientable toolholders (TCARR, TCOABS, TCOFR,
TCOFRX, TCOFRY, TCOFRZ)
When the spatial orientation of the tool changes, its tool length components also change.

After a reset, e.g. through manual setting or change of the toolholder with a fixed spatial
orientation, the tool length components also have to be determined again. This is performed
using the TCOABS and TCOFR path commands.
For a toolholder of an active frame that can be orientated, when selecting the tool with TCOFRZ,
TCOFRY and TCOFRX, it is possible to define the direction in which the tool should point.
Syntax
TCARR=[<m>]

TCOFRX
Meaning
TCARR=[<m>]: Request toolholder with the number "m"
TCOABS: Determine tool length components from the orientation of the current toolholder
TCOFR: Determine tool length components from the orientation of the active frame
TCOFRZ: Orientable toolholder from active frame with a tool pointing in the Z direction
TCOFRY: Orientable toolholder from active frame with a tool pointing in the Y direction
TCOFRX: Orientable toolholder from active frame with a tool pointing in the X direction
