NegHardOvertravelFault

Applies to: Servo Drive axes.
NegHardOvertravelFault is a Boolean attribute. It is set when Hard Travel Limits are enabled in the Limits tab of a Servo axis properties dialog box or in the Limits tab of a Servo Drive axis properties dialog box, and the axis has traveled beyond the negative direction position limit switch mounted on the machine.
NegHardOvertravelFault is a recoverable condition.
To clear a NegHardOvertravelFault:
  1. Restore the axis back within its normal operation limits, either manually or with planners.
  2. Be sure your program or fault handling routine contains either a:
    • Fault Reset (MAFR) instruction, to clear all motion faults for an axis, or
    • Shutdown Reset (MASR or MGSR) instruction to return to the axis ready operating state.
The occurrence of a NegHardOvertravelFault sets bit #3 of the respective DriveFault or ServoFault attribute, the PhysicalAxisFault attribute, and bit #0 of the AxisFault attribute.
