(Servo)
This attribute controls sense of the
Drive Fault input to the servo
module.

FeedbackFaultAction SINT GSV/SSV G11/Configuration
Sets the type of action to be taken when a Feedback Fault is encountered.
Value/Meaning
0 = shutdown - most severe action to a fault; reserved for faults that could
endanger machinery or personnel
1 = disabled drive - when the fault occurs, the drive is immediately disabled, the
servo output zeroed, and the drive enable output deactivated
2 = stop command - when the fault occurs, the axis immediately begins
decelerating the axis command position to a stop at the configured Maximum
Deceleration Rate, without disabliing servo action or the servo module's Drive
Enable Output. This is the gentlest stopping action for a fault
3 = status only - when set to status only, motion faults must be handled by the
application program.
FeedbackNoiseFaultAction SINT GSV/SSV G11/Configuration
Sets the type of action to be taken when a Feedback Noise Fault is encountered.
Value/Meaning
0 = shutdown - most severe action to a fault; reserved for faults that could
endanger machinery or personnel
1 = disabled drive - when the fault occurs, the drive is immediately disabled, the
servo output zeroed, and the drive enable output deactivated
2 = stop command - when the fault occurs, the axis immediately begins
decelerating the axis command position to a stop at the configured Maximum
Deceleration Rate, without disabliing servo action or the servo module's Drive
Enable Output. This is the gentlest stopping action for a fault
3 = status only - when set to status only, motion faults must be handled by the
application program.
FrictionCompensation REAL GSV/SSV G11/Configuration
The fixed output level added to or subtracted from the Servo Output, based on its
current sign, to break static friction, or sticktion. This value should be just under
the value needed to break the sticktion because a larger value can cause the axis
to dither.
HardOvertravelFaultAction SINT GSV/SSV G11/Configuration
Sets the type of action performed when a hard overtravel fault occurs.
Value/Meaning
0 = shutdown - most severe action to a fault; reserved for faults that could
endanger machinery or personnel
1 = disabled drive - when the fault occurs, the drive is immediately disabled, the
servo output zeroed, and the drive enable output deactivated
2 = stop command - when the fault occurs, the axis immediately begins
decelerating the axis command position to a stop at the configured Maximum
Deceleration Rate, without disabliing servo action or the servo module's Drive
Enable Output. This is the gentlest stopping action for a fault
3 =status only - when set to status only, motion faults must be handled by the
application program.
