    Hitachi WJ200 Homing function

    Hi
    I'm trying to get the homing function working on my WJ200. Here are my settings:

    P068 = (00) low speed
    P069 = (00)* Forward direction
    P070 = ( .2 ) HZ*LS frequency
    *
    C6 input (*69*)*ORL** Index Signal
    C5 input ( 70*) ORC* Start homing trigger
    *
    C021 output 11 *(23) POK* positoning complete

    When I activate pin 5 it is my assumption the spindle should turn clockwise at .2 HZ until it sees a signal on C6.

    When I activate pin 5 nothing happens.

    Has anyone ever managed to get homing working?

    Thanks
    Derek

    Fixed it. It needs to have an encoder wired up to do any positioning including homing.
    You also need to make sure your logic is wired for source and not sink.
