310 Motion Object Attributes
Servo Fault Bit Attributes The Servo Fault Bits attribute is a collection of all fault attributes that are
associated with the servo axis. Servo Fault Bit attributes are passed from a
servo module to the controller via a 32-bit value in the Synchronous Input
connection axis data structure. Thus, these fault bits are updated every coarse
update period.
All of the fault bit attributes defined below can be handled by the
ControlLogix processor as a Major Fault by configuring the associated Group
Object’s “General Fault Type Mechanism” attribute accordingly. Otherwise
any specific fault handling must be done as part of the user program.
Positive/Negative Soft Overtravel Status
If either the Positive Overtravel Status or Negative Overtravel Status bit
attributes are set it indicates that the axis has traveled, or attempted to travel,
beyond the current configured values for Maximum Positive Travel or
Maximum Negative Travel, respectively. As soon as the axis is moved back
within these travel limits, the corresponding Overtravel Status bit is cleared.
