July 2013 8.6 DCM – Dynamic Collision Monitoring 1451
DCM for
counter axes
The changes in position of manually-operated counter axes in the Manual
Operation and El. Handwheel operating modes are detected by the collision
monitoring. However, counter axes and controlled axes may not be moved
simultaneously if collision monitoring is to be effective.
In the Positioning with MDI, Program Run – Single Block, Program Run –
Full Sequence and smarT.NC machining modes, the counter axes may only be
moved at standstill, M strobe, etc., in order to ensure protection by DCM
against collisions.
The NC axes can then also be moved in the machining modes while being
protected against collision.
PLC modules Module 9063 Deactivate and activate collision monitoring
With PLC module 9063, you can influence the status of DCM collision
monitoring in the program run modes of operation.
Condition:
During program run, collision monitoring can only be deactivated during an
NC strobe.
PLC module 9064 enables you to interrogate the status of collision
monitoring for the current operating mode.
It may occur that more than one PLC cycle is executed between activation/
deactivation and feedback from the PLC module 9064.
Call:
PS B/W/D/K <Mode>
0: Collision monitoring active/inactive during program run
0: Deactivate collision monitoring
1: Activate collision monitoring
CM 9063
Error code:
If you position manually-operated counter axes during execution of an NC
program or during an individual NC block (during calculation of path
interpolations), the new positions of the counter axes cannot be detected
or considered by DCM. There is no protection against collisions.
