Kuka · KR C2 Robot Controller
The brake resistor experienced an I²t overload during operation. This indicates that the ballast switch was energized for an excessive duration. Possible causes include a defective or incorrectly connected ballast resistor, or deceleration phases in the robot program that are too long.
Click steps to track your progress.
Check the ballast resistor for defects, including open circuits or incorrect resistance values.
Verify the correct wiring and connection of the ballast resistor to the KPS module.
Review the robot program for excessively long or frequent deceleration phases and adjust if necessary.
Consider implementing an energy recovery unit to manage regenerative energy and reduce stress on the ballast resistor.
