This article only applies to PolyScope X. For PolyScope 5, see this article.

Safety Settings Overview

Universal Robots has a robust safety system to protect you and the cobot. The safety system allows you to limit robot force, power, momentum and speed, apply joint position or speed limits, restrict the robot workspace with safety boundaries, and interface with other equipment through safety rated IO.

Safety Fault Due To Mismatched Settings

When the Beacon URCap is installed or updated, it may adjust the currently loaded safety settings as appropriate for the app and the configured equipment. When PolyScope detects a change to the currently loaded safety settings and the to-be-applied settings then an alert is presented to the operator, and the robot arm status changes to "fault". This is expected, continue reading to learn how to apply the settings and resolve the fault.

Apply Beacon Safety Settings

Follow these instructions to resolve the fault and apply the updated Beacon safety settings.

  1. Dismiss the fault screen by tapping OK


  2. At the left-side of the screen, tap Application, then tap Safety


  3. At the bottom of the screen, tap Unlock


  4. If prompted, enter the safety password (default is ursafe), then tap Confirm

  5. At the bottom of the screen, tap Apply


  6. Tap Apply and restart (this does not reboot the robot)


  7. Tap Confirm Configuration

  8. At the top-left, tap the three horizontal bars, and then tap Reload
