314 Motion Object Attributes
Timer Event Fault
If the Timer Event Fault bit attribute is set it indicates that the associated servo
module has detected a problem with the module’s timer event functionality
used to synchronize the motion module’s servo loop to the master timebase of
the Logix rack (i.e., Coordinated System Time). The Timer Event Fault bit can
only be cleared by reconfiguration of the motion module.
Module Hardware Fault
If the Module Hardware Fault bit attribute is set it indicates that the associated
servo module has detected a hardware problem that, in general, is going to
require replacement of the module to correct.
Attribute Error Code
When an Axis Configuration Fault occurs, one or more axis parameters
associated with a servo module or device has not been successfully updated to
match the value of the corresponding parameter of the local controller. The
fact that the configuration of the servo axis no longer matches the
configuration of the local controller is a serious fault and results in the
shutdown of the faulted axis. The Attribute Error Code is reset to zero by
reconfiguration of the motion module.
Axis Configuration Fault information is passed from the servo module or
device to the controller via a 16-bit ASA status word contained in the Set
Attribute List service response received by the controller. A Set Attribute List
service to the motion module can be initiated by a software Set Attribute List
service to the controller, or by an SSV instruction within the controller’s
program, referencing a servo attribute. Various routines that process responses
to motion services are responsible for updating these attributes.
The Set and Get service responses provide a status response with each
attribute that was processed. That status value is defined by ASA as follows:
UINT16, Values 0-255 (0x00-0xFF) are reserved to mirror common service
status codes. Values 256 – 65535 are available for object/class attribute specific
errors.
