Beckhoff · TwinCAT 2 NC

What does 4505 mean?

The value for the activation of the following error monitoring (velocity) is not allowed, as the value range is limited to [0, 1]. This parameter enables or disables the system's ability to detect deviations between commanded and actual velocity. An invalid setting means critical safety monitoring might be disabled or misconfigured, leading to uncontrolled speeds.
