Danfoss · VLT Micro Drive FC 51
An attempt was made to set a parameter value that falls outside its defined minimum or maximum limits. This is a common error when entering values manually via the LCP or programmatically via communication, protecting the drive from unsafe or illogical settings.
Click steps to track your progress.
Review the drive's programming manual for the specific parameter to confirm its precise minimum and maximum permissible values.
Adjust the entered value (via LCP or communication) to be within the documented min/max limits of the parameter.
Check scaling of analog inputs (e.g., Parameter 6-10, 'Min reference', and Parameter 6-11, 'Max reference') to ensure the input signal does not produce an out-of-range value.
Examine any interdependencies between parameters (e.g., ensure Parameter 4-13, 'Min output frequency', is less than Parameter 4-12, 'Max output frequency').
If using communication protocols, verify the data type and range mapping in the PLC or HMI program matches the drive's parameter specifications.
