Causes

  1. Y and B axes share a servo drive on some Integrex machines — when the drive is marginal or aged, the least-used axes (Y, B) throw overload first, especially after the machine has been sitting and is cold.

      If Y and B share a drive, I'd treat this as drive or cabling before chasing encoder ghosts. Since it only shows up after sitting and hits the least-used axes, a marginal connection or rebuild candidate drive sounds more …

How to clear it

  1. 1

    Confirm which axes share a drive on your machine before chasing the encoder. If Y and B share, pull and inspect the drive connectors and consider sending the drive out for rebuild before buying a new encoder.

      Servo drives are probably the most common failure on older Mazaks. If your Y B axis are on the same drive, keep that little tidbit in mind....
  2. 2

    If you only need axes other than the faulty one for current work, you can disable the failed axis in parameters as a stopgap (per a senior PM responder's suggestion to OP).

Additional notes

Alarm 24 'Overload' with the parenthetical 4,0,0051 / 0052 / 0058 pattern points at specific axis numbers in the servo bus. Cross-reference the third number against the drive layout in the machine's electrical drawings.

Confidence: medium · Single PM thread but cross-confirmed within the thread by two senior responders. OP had not posted final fix at time of capture.
