MD21186 may not be rewritten in a program with call CYCLE800.
If several swivel data sets are declared per channel, and if machine functions need to be
activated on changeover between swivel heads or tables, an M command can be issued in
the PLC program on switchover to another swivel data set.
MD22530 $MC_TOCARR_CHANGE_M_CODE
= 0
< 0
Example
Number of swivel data sets in channel 1
MD22530 $MC_TOCARR_CHANGE_M_CODE
Programming swivel data set 1 (TCARR=1)
Programming swivel data set 2 (TCARR=2)
With the output of the M commands, the PLC can limit or invert the spindle speed or clamp
or release the rotary axes, for example.
Setting the workpiece, tool and rotary table reference
Using the following machine data, you can set the workpiece, tool and rotary table reference
system frames or you can influence the behavior of the system frames.
Application: System frames can be active after Reset or Power On, in order to retract a drill
from a swiveled position without causing a collision, for example.

Orientation vector remains at T0 or D0 (no tool)
Used for machine kinematics, types "T" and "M"
See parameter $TC_CARR34
In CYCLE800, the WCS is recalculated when there is a value in the zero offset (ZO)
of the rotary axes.
If values are entered in the zero offset of the rotary axes of the active swivel data set,
the basic position of the swivel data set and therefore also the basic position of the
WCS can change.
A value in the ZO of the rotary axes acts as offset of the tool holder that has
orientation capability. The Work remains unchanged.
No swivel data set change
M code + number of the swivel data set for the swivel data set change
Tool parameter setting
Offset of the rotary axes for a tool holder
with orientation capability from the zero
offset of the rotary axis.
