Fault Troubleshooting

The list that follows includes pages to help you troubleshoot specific faults. This is not a list of all possible faults. For faults not included in the list, refer to the Troubleshooting Guidelines section on this page.

• Amplifier Fault

• Clockwise (CW) End-of-Travel Limit Fault

• Counterclockwise (CCW) End-of-Travel Limit Fault

• Emergency Stop Fault

• FeedbackInput0 and FeedbackInput1 Faults

• Over Current Fault

• Position Error Fault

Troubleshooting Guidelines

General Tips

• Refer to the Fault Mask Bit Descriptions section of the FaultMask Parameter page for more information about each of the axis fault bits.

• Refer to the Fault and Error Functions page for more information about axis faults in Automation1.

• When you edit parameters in the Axes Category, make sure that you have the correct axis selected in the drop-down window.

• If you start to get an unexpected fault, examine your system wiring.

Configuring Faults

• After you complete Machine Setup, do the items in the Checklist tab of the Automation1 Studio application sidebar.

• Configure the FaultMask Parameter to choose which faults the controller can detect.

  • During Machine Setup, the FaultMask parameter is modified based on the mechanical devices in your system. It is not always fully configured during this step.

  • Make sure that all faults that should be monitored by the controller are selected and all faults that do not apply to your system are cleared.

  • Aerotech recommends that you do not mask the faults that follow:

    • Position Error

    • Over Current

    • Feedback Input 0

    • Feedback Input 1

    • Emergency Stop

    • Gantry Misalignment

  • The faults that follow cannot be masked:

    • Amplifier

    • Amplifier Temperature

    • Motor Supply

    • Internal

  • Note that if you mask the Emergency Stop Fault, the Safe Torque Off (STO) hardware will still operate.

    • Refer to the hardware manual for your drive for more information.

    • Install the STO bypass connector if you are not using STO to override the safety circuit. On drives with an STO input, a bypass connector is included with the order.

• Make sure that the applicable fault threshold parameters are configured correctly based on your system specifications.

  • You can find these fault threshold parameters in the Protection tab in the Configure workspace.

  • You can find more information about each parameter in the Parameters section in Help.

  • When you are in Automation1 Studio, if you have the Help tab open while you are editing parameters in the Configure workspace, the applicable Help page shows in the sidebar.

• To change the axis behavior after it gets a fault, refer to the FaultMaskDecel Parameter and FaultMaskDisable Parameter pages.

• You can adjust more settings with the FaultSetup Parameter.
