114 Function Manual, 11/2006, 6FC5397-0BP10-2BA0
Activation of kinematic types P and M
With kinematics of type P and M the selection of a toolholder activates an additive frame
(table offset of the toolholder with orientation capability), which takes into account the zero
point offset as a result of the rotation of the table.
The zero offset can be written to a dedicated system frame $P_PARTFR. For this, the bit 2
must be set in the machine data:
MD28082 $MC_MM_SYSTEM_FRAME_MASK (System frames (SRAM))
The basic frame identified by following machine data is then no longer required for the zero
offset:
MD20184 $MC_TOCARR_BASE_FRAME_NUMBER (Number of the basic frames for taking
the table offset)
Activation of kinematic type M
With kinematics of type M (tool and table are each rotary around one axis), the activation of
a toolholder with TCARR simultaneously produces a corresponding change in the effective
tool length (if a tool is active) and the zero offset.
Rotations
Depending on the machining task, it is necessary to take into account not only a zero offset
(whether as frame or as tool length) when using a rotary toolholder or table, but also a
rotation. However, the activation of a toolholder with orientation capability never leads
directly to a rotation of the coordinate system.
TOROT
If only the tool can be rotated, a frame whose Z axis points in the direction of the tool can be
defined with TOFRAME or TOROT.
