18.3 Description of collision protection
An alarm is output as soon as the axes reach zero speed.
Risk of collision when starting
If the axes are forced to brake, the positions displayed in the workpiece coordinate system
are incorrect!
These are not re-synchronized again until a system RESET.
If the axes are already violating the minimum clearance when collision protection is activated,
they can only be traversed in one direction (retraction direction). The retraction direction is
configured in machine data:
MD63543 $MA_CC_PROTECT_OPTIONS
The collision protection status is optionally displayed in axial VDI-Out byte of the PSlave:
DB31, ... DBX66.0 (activate monitoring)
● DB31, ... DBX66.0=1 → collision protection active
● DB31, ... DBX66.0=0 → collision protection inactive
This output is activated via Bit7 in machine data of the PSlave axis:
MD63543 $MA_CC_PROTECT_OPTIONS
