    Hello friends, I have a problem with the main pile delivery of an MO 4 unit 97.
    the main pile delivery works for a few seconds and hangs, you have to restart the machine, it starts working and hangs, I need help.
    error code HAK_2 7FFD
    I change the Hak 2, the same thing

    Exchange LTK500 boards, possible power supply issue. Brake on pile motor may require attention.

    Could be a battery motor overheating problem. Try to measure the current of the phases at the time of start-up
    (Winding and internal motor insulation in doubt)
