    Hi all,

    I've downloaded Fidocadj, and did a draft for my milling machine card.

    Power 1500 W
    GBU 1506 output 340 V dc and 5 A average current.


    If you could correct mistakes it would be great.

    My questions:

    - R1 value 1400 Ohm, my choice (15 - 1.6 ) / 10 mA , right ?
    1/2 Watt or other ?

    - About R4 , what value, also power ?

    - 1N4744 ?

    Last question:

    I have to power :
    - 3 VO3120
    - 3 Tracor TMA1512D
    - 1 MC 33035
    - 1 MC 33039

    1 A or more needed?


    FP7G5OUS60 is a Fairchild Power igbt module,link below:
