Motion supervision on axis two after downtime.

    Code
    We have a problem with the ABB S4C robot. During a longer standstill and an attempt to start in automatic mode, the robot axis 2 overload error occurs. After switching to manual mode and moving, the robot starts and works without errors. What could be the reason?

    In addition to Lemster68 recommends:

    Could be the axis brake not wanting to release the first time. Weak spring(s) on one side, excessive dust and/or uneven shaft wear can cause binding.

    Make sure axis 2 has the recommended level of lubricant.

    Could be a dirty contactor where the 24V Brake voltage is reduced and axis 2 is the first to overload.


    Which model robot?

    Does it always fault after long downtimes?

    What kind of environment is the robot in?
