    Hi there
    Just stumbled upon this thread, impressive work !!! Thanks Mihai for your great work !! It is now a must-build for me too!
    A first question to @Mihai: are you selling PCB's? Or is anybody else having some PCB's to sell here?
    Thank you

    hallo, mihai..Thanks for your project

    i was following your project for couple a weeks.. I have IAI actuator IS-SYM-8-60 with builtin 60 watt servo motor, 60volt and 768 ppm encoder, i built a copy prototype based on your schematic and it was success everything work like a charm, connect to PC with your servo tuner software, run setup change parameters work nicelly..

    I try to attach the motor and encoder, the driver read encoder data result 768/turn but the motor run erraticlly cogging and the diver cant maintain position.

    Hi Minhai,

    Firstly thank you for your dedication and generosity of sharing this.

    How is the new project coming along?

    I'm planning on making one of these firstly to see if I'm capable and if so I'll convert my 4Nm steppers to servo driven. Could I rewire my 4 wire or maybe it 8 I can't remember and run it as a dc motor and attach the encoder onto it? I would love to do this with a AC induction motor also. Is this possible or would it be very difficult with coding etc... I'm very beginner level of programming.

    Thanks again
    Dave

    Hi...i am a new user here. In my case i will stick to old chemical way for the next versions and maybe drill the holes on CNC.I am waiting for a bigger motor. The board will work with higher currents, it's just a problem of final stage Mosfets.

    I think it does not work too, lower side and upper side switches at the same time.

    Maybe Mikroelektronika use special .hex file format, see from 160. line:
    :1003A6000FB6BFB3B1FF02C00000FBCFF89432BC5A
    :1003B60021BCBFB3B160BFBB0FBE10B5012F0895FE
    :0003C60037
    :10097000B1EAB4BDB1E0B5BDB0E0B7BDB0E0B8BD5F
    :10098000B1EAB0938000B1E0B0938100B0E0B093E1
    162. line is invalid.
