    HAAS SL-20 ALARM 292 320V POWER SUPPLY

    Hi all,

    i have a Haas SL-20 2007, when i power up a have the alarms below:

    102 SERVO OFF
    292 320 POWER SUPPLY FAULT
    107 EMERGENCY OFF

    There in no other alarm and it doesn't come off when I cycle the power.
    when I measure the dc power output is 325v and the DC BUSS in the dignosys is the same 325v
    when called my HFO (ho is 600km away ) he told me to change the regen and i did it without any change.

    do you have any ideas please???????

    thank you in advance

    I’m not an expert on this but…

    Will the error clear if you hit the reset button rapidly 3 or 4 times in a row?

    What is your parameter 294 set to? Is it 270 ? You could temporarily try setting this value to 0 and see if that works after a power cycle. The vector drive might be reporting the wrong voltage to the maincon.
