12.10. Configure the FAULTMASK
This axis parameter determines which faults the system will detect. The parameter is a bit
mask where each bit corresponds to a specific fault. Setting a bit to a one enables
monitoring of the fault assigned to that bit. Conversely, clearing a bit causes the system to
ignore that fault if it occurs. If a fault is detected, it’s bit value is “anded” into the FAULT
axis parameter value.
Each bit set in this parameter should have a bit set in at least one of the other mask
parameters (DISABLEMASK, HALTMASK, AUXMASK, ABORTMASK, INTMASK
and BRAKEMASK) to define the action to occur for that fault. If you set a bit in the
FAULTMASK, but fail to set any corresponding bits in one of the other masks listed
above, then the FAULT parameter will be set, but no axis action will occur. These actions
will occur immediately after detection of the fault, usually within a millisecond.
You can also trigger program-related actions to take place when an axis fault occurs, with
the TaskFault task parameter. CNC programs may be stopped when by axis faults, via the
HaltTaskOnAxisFault task parameter.
