    Hi sir;

    Please test the module SLT for Drive Main Motor , specially;

    a) SBM1
    B)SBM2
    Both module are Power rectifier , responsible, for backward, forward inching, Run the press, for the winding of Armature, and field circuit of main motor

    Can be open, or short circuit, or Leak, and by that reason the machine will STOP and NOT run.

    C)Clean very well the module from Oxide, and Retight the wire, Examine the rest of electronic components

    D) Test the input Voltage of Vac, must be in 10% up or down. NOT more.

    Blessing

    Yes, Chock gave you steps to follow. Unless you’re waiting on an easier fix, which is unlikely, suggest you follow his directions. You may wish to also check physical brake (the one on main motor).

    Hi sir;

    Please do my steps very carefully, otherwise, you will take around the same problem.
