Following error monitoring (position) not allowed
Beckhoff · TwinCAT 2 NC
Was bedeutet 4504 ?
The value for the activation of the following error monitoring (position) 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 position. An invalid setting means critical safety monitoring might be disabled or misconfigured.
Häufige Ursachen
- The parameter for activating following error monitoring (e.g., P6-05, Position Error Monitor) is set to an invalid value other than '0' (disabled) or '1' (enabled).
- Attempt to enter a boolean 'TRUE'/'FALSE' or other non-numeric input into a parameter expecting '0' or '1'.
- Configuration tool or HMI error that allows or defaults to an out-of-range value for this binary parameter.
- Corrupted parameter block within the drive or controller's non-volatile memory.
Reparaturschritte & Checkliste

- 1
1. Access the following error monitoring parameter (e.g., P6-05) and explicitly set its value to either '0' (disabled) or '1' (enabled).
- 2
2. Ensure any automation logic or HMI inputs interfacing with this parameter are configured to send only '0' or '1' as valid states.
- 3
3. If experiencing persistent issues, try resetting the parameter to its factory default value (if allowed) and then re-entering '0' or '1'.
- 4
4. Perform a complete parameter download from the configuration software to the drive to overwrite any corrupted values.
- 5
5. Review the system's safety requirements and tuning guide to determine whether following error monitoring (P6-05) should be enabled (1) or disabled (0).
