Motoman Backlash compensation

    Hello

    Two old welding robots, have a big backlash. Productivity is lower because a lot of repeated program adjustments.


    I am looking for some kind of Parameter for backlash compensation.

    There is no backlash compensation. Call Yaskawa you can have an audit done to find out what axis or drives need to be replaces, or get a rebuilt arm as a core exchange, or have the robot rebuilt or buy a new robot.

    Thanks Robodoc,

    We got the same answer from Yaskawa.

    My customer already ordered 2 new Robots.

    The system works 24/6, it is not practical/economical to dismantle and send the Robots to Germany or Sweden for a complete rebuilt. We guessed that the price for a full mechanical overhaul will be about half the price of a new system. (Plus production lost...)


    Milling machines have a Backlash compensation, and I understand that because they have a mechanical load on the Tool, it is working.


    Welding robots only have their own complex 3D Inertia load, but I wonder if no other robot manufacturer have some kind of Backlash compensation ?
