Error codes

What a robot’s error code means, from the maker’s own directory, with a link to the page where the maker says what to do about it.

Type the code from the teach pendant, or words from the message. Each directory is grouped the way the maker prints it: by robot generation, then by section.

Cause, as the directory gives them

  • When the emergency stop is active, the Robot Arm powers off. The controller is responsible for sending the power off command. This error is generated if the safety system detects that the Robot Arm still has power

From Universal Robots’s own error code directory. The steps to fix it are the maker’s and are on the page linked above, not copied here.
