    Greetings to all. May God stop the ravaging pandemic in time and heal the world so that we can be happy people again.
    I am working on an SM-74-2, 2001, Compact Cp-T. The machine had been running and inching. At a point;

    1. inching refuse Double-clicking for inching mode refused to retain the mode at all points. Machine continue to inch if one can press and hold the inching mode button - safe button on old machines.

    2. On run mode, ma fine will turn only one revolution and stop.
    DNY TEST - t=0
    S-HWI FEFF
    S-MOT FF7F.
    No break on both encoder cables, the motor encoder and the main encoder for machine degree . Plugs at either ends seems to be ok too

    I need suggestions on how best to go forward on this 2 issues.

    Thanks.

    Hi:Sir
    Test for 1) HW1: Speed ??determined by HWI is outside of the allowable range
    test 2) MOT: Induced voltage stays below the setpoint value eng
    Use a good electronic Tec or Professional Electronic Engineer for this test
    Blessing
