    hi friends

    we have a MC500H machining center with osp5020m system

    we are getting an alarm " 139 alarm A - CA axis travel limit over "

    but we couldn't understand what CA means.

    could be carriage (machine axis for tool change). Check your ATC mechanism.

    I think it is from shifter mechanism. On APC shifter. Open the cover you will see the motor and the reel and mechanism.
