Parameters U511 User’s Manual
4-70 Aerotech, Inc. Version 1.1
4.9.6. “Halt queue”
This parameter specifies a fault mask pattern (corresponding to the faults in Table 4-52 on
page 4-68) that causes the UNIDEX 511 to stop reading information from the internal
queue (that is, stop program execution) if any of the selected conditions are true (i.e., if
any of the selected faults occur). The default setting for this parameter is
FFFF FFF0 8E00.
When this condition goes into effect, the commanded velocity will be immediately
forced to zero. No ramping will occur and the contouring of the motion will be
stopped.
4.9.7. “Abort motion”
Parameter x60 specifies a fault mask pattern (corresponding to the faults in Table 4-52 on
page 4-68) that causes the corresponding axis of the UNIDEX 511 to ramp to a stop and
wait for an acknowledgment if any of the selected conditions are true (i.e., if any of the
selected faults occur). All active axes will decelerate linearly using their individual
acceleration/deceleration rates. The default setting for parameter x60 is
FFFF FFFF 9E78.
The ABORT cycle does not preserve the contour of the motion.
4.9.8. “Enable brake”
Parameter x61 specifies a fault mask pattern (corresponding to the faults in Table 4-52 on
page 4-68) that causes the brake output to be activated immediately if any of the selected
conditions are true (i.e., if any of the selected faults occur). For more information about
the brake output, refer to the Chapter 10: Technical Details. The default setting for this
parameter is FFFF FFF0 0000.
Only one axis should specify a non-zero mask for the brake. The brake will be
automatically disengaged when the axis is enabled and engaged when the axis is
disabled.
The brake fault mask is usually configured to turn the brake on when a “disable”
error occurs.
