    This problem was intermittent Sometimes it would happen and sometimes it would run fine. The past 2 months we had a lot of problems with a certain product and program. The Spindle drive unbit would show an alarm when the screen displayed a 280 alarm. I adjusted some of the settings within the spindle drive such as the braking time and other settings related to the braking resistir and timing. I also changed a setting that said what kind of resistors they are, I turned it to Disable. This worked well and have no problems for 30 days. I dont know if changing the setting to disable will cause other problems though.

    Have you check the circuit related to the "machine ready"?
    There is a relay that send you this signal. May be the relay is bad, you can try changing it.

    Regards
