  1. Re: Yaskawa Spindle Drive fails on deceleration

    This is really digging into the archives but it was something like this:

    Re: Cadet V 5020M 4th A Axis retrofit

    So it turns out you need to put in a BL-25E-20T motor which appears to be pretty hard to find. It's that or trying to get Okuma to reprogram which is highly unlikely. Anyone out there have one of...

  13. Re: Yaskawa Spindle Drive fails on deceleration

    Mac,
    They are in there, just not sure if they work right
