Switching The Coupling On/Off - Siemens SINUMERIK 840D sl Function Manual

Requirements
● The CC_Master and CC_Slave axes must be either both rotary axes or both linear axes.
● Spindles cannot be coupled by this function.
● Neither the CC_Master nor CC_Slave axis may be an exchange axis
($MA_MASTER_CHAN[AXn]=0)

Switching the coupling ON/OFF

Activating the coupling
● Activating the 1:1 coupling. Monitoring of the tolerance window is active.
CC_COPON([<axis1>][<axis2>][<axis3>][<axis4>][<axis5>])
● Activating the 1:-1 coupling (mirror). Monitoring of the tolerance window is not active.
CC_COPONM([<axis1>][<axis2>][<axis3>][<axis4>][<axis5>])
Axis name
An axis can be specified via:
● Machine axis name
● Channel axis name
● Geometry axis name
Boundary conditions
● A programmed axis must be involved in a coupling.
● CC_Master axes, CC_Slave axes or both can be programmed simultaneously. All defined
couplings are switched on with CC_COPON or CC_COPONM.
● An alarm is output if an axis not involved in a coupling is programmed.
NC/PLC interface signals
All NC/PLC interface signals of a coupling refer to the CC_Slave axes.
● DB31, ... DBX97.1 (coupling active)
● DB31, ... DBX97.2 (mirroring active)
● DB31, ... DBX24.2 (suppress CC_Slave axis coupling)
If the coupling is suppressed, an alarm is not output for the CC_Slave axis.
Deactivating the coupling
CC_COPOFF([<axis1>][<axis2>][<axis3>][<axis4>][<axis5>])
As for switching on the coupling with the difference that no alarm is output if an axis is
programmed that is not involved in a coupling.
An existing coupling can also be switched off by the axial NC/PLC interface signal of the
CC_Slave axis.
