    Hi our KTK Mentor Drive has overvoltage problem. We changed tge circuit board as Pulse Transfomers were blown on original circuit board. On replaced second circuit board now Capacitor and two EL supply fuses have blown.

    The motor runs for 5 -10 minutes and then blows the fuse. Looks as though over voltage problem somewhere.

    It’s running a 99KW motor but can’t see any issues with motor.

    A waste of resources by posting three 'useless' photos!

    A schematic would be far, far more useful. We can determine nothing from pictures of fuses.
