MD21186 may not be rewritten in a program with call CYCLE800.
If several swivel data sets per channel are agreed and machine functions are to be started
when changing the swivel heads or swivel tables, an M-command can be activated in the PLC
program when changing the swivel data set.
MD22530 $MC_TOCARR_CHANGE_M_CODE
= 0
< 0
Example
The PLC can limit or invert the spindle speed or clamp or release the rotary axes, for example,
by outputting the M-commands.

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, e.g. to retract a
drill from a swiveled position without causing a collision.

Bit 4

Orientation vector remains at T0 or D0 (no tool)
Used for machine kinematics, types "T" and "M"
See parameter $TC_CARR34
The changed orientation vector remains at T0 or D0 (no tool)
Bit 19 acts only with bit 10 = 1
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
