18.2 Description of MCS coupling functions

The following functions are not possible for a CC_Slave:
● To be a PLC axis
● To be a command axis
● To be traversed separately from the CC_Master in JOG mode
Tolerance window
When the coupling is active, the actual values of the CC_Master and CC_Slave are monitored
for compliance with a parameterizable tolerance window.
Programming a CC-Slave
If a CC_Slave is programmed in a channel, either an alarm is displayed or the axis is requested
for the channel via an implicitly triggered axis interchange (GET), depending on the setting in
machine data:
MD30552 $MA_AUTO_GET_TYPE = <GET type> (automatic GET for axis)
Switching the coupling on/off
A coupling is switched on and off via OEM-specific language commands and can be active in
all operating modes.
Collision protection
In order to protect the machining heads against collision in decoupled operation or in mirrored
coupling, a collision protection can be parameterized. The activation is performed via machine
data or the NC/PLC interface. The assignment of the protected pairs is not dependent on the
CC_Master and CC_Slave pairs.

Defining coupling pairs

A CC_Slave axis is matched to its CC_Master axis via the following axial machine data:
MD63540 $MA_CC_MASTER_AXIS (specifies the CC_Master axis assigned to a CC_Slave
axis)
The coupling's axes can only be changed when the coupling is not active.
A CC_Slave axis is displayed in axial VDI-Out byte:
DB31, ... DBX97.0 (axis is slave axis)
