I have an IRB 120 arm with IRC5 Compact Controller. Within a few seconds after booting I observe the following error message:
20252: Motor temperature high, DRV1
Description: Over temperature in Manipulator Motor. Make sure to let the Motor cool down before ordering Motors On again.
Actions
1) Wait until the overheated Motor has cooled down before ordering Motors On again.
2) If optional air filter is used, check if it is clogged and has to be exchanged
Motors are off and cold. The error follows the controller when I swap to a known good robot arm. Given these facts, the issue appears to be in the controller.
Is there any additional diagnostics I can use further isolate the problem using the FlexPendant or RobotStudio? Anything else I should check on the hardware? Any help would be much appreciated.
