Cause : Data processing error- Main program stack overflow comes when the HF12 trip indicates that the main program stack over flow has occurred. The stack can be identified by the sub-trip number. This trip indicates that the control PCB on the drive has failed.

  • This is a hardware fault and cannot be reset.
  • Check drive hardware.
