U511 User’s Manual Parameters
Version 1.1 Aerotech, Inc. 4-69
4.9.2. “Global fault mask”
Parameter x55 is the “Global fault mask” parameter. This parameter defines a "global"
48-bit pattern (mask) that either enables (1) or disables (0) detection of fault conditions
associated with the corresponding bits for all tasks. The appropriate fault bit (see Table
4-52 on page 4-68) must be set to a "1" for the associated faults to be detected and
reported. The default bit pattern for this parameter is FFFF FFFF 319F.
4.9.3. “Disable”
Parameter x56 defines a 48-bit pattern mask (corresponding to the faults listed in Table 4-
52 on page 4-68) that specifies which fault conditions (if any) are used to disabled the
associated axis. A “1” in a bit position indicates that the corresponding fault condition
will disable the associated axis. A “0” in a bit position indicates that the corresponding
fault condition is ignored. For example, if bit # 0 (position error bit) of parameter 356 is
set to 1, then a position error fault on axis 3 will cause that axis to be disabled. The
default bit pattern for the “Disable” axis fault mask is FFFF FFF0 EF87.
4.9.4. “Interrupt”
Parameter x57 defines a 48-bit pattern mask (corresponding to the faults listed in Table 4-
52 on page 4-68) that specifies which fault conditions (if any) are used to generate a
hardware interrupt (when any of the selected fault conditions are true). A “1” in a bit
position indicates that the corresponding fault condition will generate a hardware interrupt
if the fault occurs. A “0” in a bit position indicates that the corresponding fault condition
is not used to generate a hardware interrupt. For example, if bit # 14 (emergency stop bit)
of parameter 257 is set to 1, then an emergency stop error fault on axis 2 will cause the
UNIDEX 511 to generate a hardware bus interrupt. If multiple bits are set to 1 in
parameter x57, then a hardware bus interrupt is generated if any of the faults associated
with those bits occur.
The default bit pattern for the “Interrupt” fault mask is FFFF FFF0 0000 (all assigned
bits are set to 0).
4.9.5. “AUX output”
A fault (see Table 4-52 on page 4-68) is considered to be an AUX output fault if the
corresponding bit in this “AUX output” fault mask is set to 1. If any of the selected faults
occurs, then the UNIDEX 511 will set an output low. This output number is selected in
parameter x54 (Output for “AUX output”). The default setting for this parameter is
FFFF FFF0 0000 (no faults are selected, therefore “AUX output” faults are effectively
disabled).
