    Default blown spindel controller MBL-1100-300H

    Hello
    I have a Syil XP5.(from 2009). The servo controller of the spindel is out of order. The machine moves without the spindel controler.
    The print type: MBLC-1100-300H / 1100W/3500RPM/220V. I would like to substitute the blown part.
    I attached two picture and marked the blown part with a yellow pen. Is that a opto coupler? Does anybody know the type and maybe where to buy.
    Thanks a lot.

    without the circuit diagram of the board and details of the part numbet of the burnt IC

    its going to take time to reverse engineer the board

    going by your photo
    blown spindel controller MBL-1100-300H-pcb-jpg

    it looks like the burnt component is something like this VIPER12A :-

    blown spindel controller MBL-1100-300H-viper12adip-e-jpg

    data sheet:-
    blown spindel controller MBL-1100-300H-viper12adip-e-jpg

    or possibly KA7552A

    it will help to know the part numbers of the 4 parts arrowed

    and to see a detailed photo of the underside of the board

    Probably viper22a 8 pin switch mode controller.
    Almost any part of control wiring touching chassis can kill this device.
    Other parts mostly regulators, 5v, 6v? 12v. Maybe even 3.3v. Probably ok, if you are lucky
    Talk to you friendly syil agent! Best of luck.



    Super X3. 3600rpm. Sheridan 6"x24" Lathe + more. THREE ways to fix things: The RIGHT way, the OTHER way, and maybe YOUR way, which is possibly a FASTER WRONG WAY!

    You could try MINI LATHE - MILL BOARD REPAIR SERVICE. I've used him a couple of times. Great service.

    On one side there are 4 connector and on the other side there are 3 conector.
    Attached a picture from the back side. I saw ooictures of other Syil spindel controler and they look pritty much the same.

    seeing the photo of the under side of the PCB

    the TOP221-227 Family of three-terminal Off-line PWM Switches looks more like the IC used

    blown spindel controller MBL-1100-300H-typical-application-gif

    PDF data sheet
    38-POWERINT-TOP221~227.pdf

    it looks like they have cut off pin 3 -
    one of the six source terminals to increase the insulation between the source and the control pin 4
