    Default Turret problem doosan 2500 sy alarm 2047

    Dealing with a turret problem on a Doosan 2500sy, an alarm numbered 2047 appears at the end of the programming and on the change while reloading from position 1 to the next position (start of next cycle), a trembeling and noice that I cant determ if it occurs from the clamp or from a sudden and iregular rotation of the motor back and forth. Never the less, I adjusted and checked the proximity sencor of the turret but nothing changed.
    Please take notice that this only happends at the beggining and the end of the cycle and mainly (but not only) when the ending tool is the number 1. We currently dont use the possition number 1, the problem has improved a lot but not fixed, as sometimes we have the same issue.
    When we turn the turret manualy this never occurs, regardless of the number of times we turn it.

    Any suggestions???

    Is the turret loaded with tools in an "out of balance" way?

    Alter K5.4 to manually disengage the brake.
    If the turret rotates, it is out of balance.
    If it does not rotate immediately, hand turn it 90 degrees, if it turns when you let go - it is out of balance.

    Alter tool layout to.make it more balanced.

    Hi thanks for your reply,

    The clamping - un clamping is hydraulic, but as I described above the noice and the movement of the turret, is not clear to understand if it come from the clamping or the motor. We noticed that when this occurs, sometimes the movement (trembeling) is not 2or3 cm and becomes 10cm roughly but rarely 10cm.

    HI thanks for your reply,

    We tried all mentioned, balancing the tools, adjusting the proximity switch... nothing seams to solve the problem. I forgot to mention that this takes place after a 2 to 2 1/2 hours of working, and only on the end and begining of the cycle. So we thought that maybe the temperature ?? We also change the hydraulic oil of the power unit, used in case, but stil nothing.

    Do you get any alarm on the servo drive of the turret? (Inside the electrical cabinet )

    If not: 1 thing to try...
    Use K5.4 to unclamp the curvic and re-clamp, feeling it pull the curvic into place. Then unclamp and re-clamp in that position again.
    Now it is perfectly locked in "dead center" of curvic gear.
    Perform an Origin Set of the turret servo to re-validate the VPF (verify position flag) marker in the encoder that tells the turret that it is in the right position.
    Origin Set instructions are in the blue-book (uses parameter 8)
