Numerical control system with following error monitor |
摘要 |
A following error monitoring system for detecting axis positioning failure modes in a numerical control system and causing a cessation of movement as a result of the detecting of such failure mode. The system comprises an integration means and a time delayed negative feedback of the output of the integration means provides a "predicted following error" signal which is used to provide a comparison to a "error threshold signal" for determining unacceptable axis positioning deviation.
