Motion Error Codes, faults, and attributes
Rockwell Automation Publication MOTION-RM002H-EN-P-February 2018 599
SercosErrorCode INT GSV G10/Status
Used to identify the source of the drive parameter update failure that results in
the AxisConfigurationFault. The error codes are derived from the IEC-1394 SERCOS
Interface standard.
ServoFaultBits DINT GSV G11/Status
Bit Bit Name Meaning
0 PosSoftOvertravelFault Sets when the axis travels or
attempts to travel beyond the
configured value for Maximum
Positive Travel.
1 NegSoftOvertravelFault Sets when the axis travels or
attempts to travel beyond the
configured value for Maximum
Negative Travel.
2 PosHardOvertravelFault Not Available. Sets when the axis
travels or attempts to travel
beyond the maximum position
limit set by the hardware limit
switch mounted to the machine.
3 NegHardOvertravelFault Not Available. Sets when the axis
travels or attempts to travel
beyond the minimum position
limit set by the hardware limit
switch mounted to the machine.
4 FeedbackFault Sets when the differential
electrical signal for one or more of
the feedback channels are at same
level or loss of feedback power or
common electrical connection
between servo module or drive
and the feedback device.
5 FeedbackNoiseFault Sets when simultaneous
transitions of feedback of A and B
are detected by the servo module.
6 AuxFeedbackFault Not Available. Sets when the
differential electrical signal for one
or more of the feedback channels
are at same level or loss of
feedback power or common
electrical connection between
servo module or drive and the
auxiliary feedback device.
7 AuxFeedbackNoiseFault Not Available. Sets when
simultaneous transitions of
feedback of A and B are detected
by the servo module.
8 PositionErrorFault Sets when the axis position error
exceeds the value set for Position
Error Tolerance.
9 DriveFault Sets when the external servo drive
detects a fault and reports it to the
servo module via the Drive Fault
input,
