4507

Following error filter time (position) not allowed

Beckhoff · TwinCAT 2 NC

What does 4507 mean?

The value configured for the following error filter time (position) is not allowed, as it must be within the range [0.0, 600.0] seconds. This parameter filters out high-frequency noise from the following error signal, preventing nuisance trips. An invalid filter time can lead to either excessive false alarms or a failure to detect real errors.

Common Causes

  • Parameter Px-03 (position following error filter time) is set to a value outside the allowed range of [0.0, 600.0] seconds.
  • An automatic tuning routine or external PLC command has attempted to write an out-of-bounds value to the filter time parameter.
  • Drive firmware incompatibility with an imported parameter file containing an invalid filter time value.
  • User configuration error by manually entering a value greater than 600.0 seconds for the filter time.

  1. 1

    Connect to the drive using the manufacturer's software and navigate to the parameter settings for position control.

  2. 2

    Locate the parameter for position following error filter time (e.g., P5-03) and read its currently configured value.

  3. 3

    Set the position following error filter time parameter (e.g., P5-03) to a value between 0.0 and 600.0 seconds (e.g., 0.05 seconds for minimal filtering).

  4. 4

    Store the modified parameter settings in the drive's non-volatile memory and cycle power to the drive.

  5. 5

    Check the PLC program for any commands that write to P5-03 and ensure they provide values within the acceptable range.
