Illegal Parameter Index

¿Qué significa 8.0.00.10 ?

The parameter index specified in the communication request is invalid or not recognized by the inverter. This implies an attempt to access a non-existent parameter or a typo in the parameter address. This error is returned under error class 8 (other error) and prevents the requested parameter operation.

• PLC or HMI program attempting to write or read a parameter address (e.g., Modbus register 40003) that does not exist in the inverter's parameter map for its current firmware version.
• Typographical error in the parameter index mapping within the supervisory control system (e.g., requesting P1-1000 instead of P1-0001).
• Mismatch between the configured inverter model/firmware in the fieldbus master and the actual inverter unit installed, leading to an incorrect parameter address range.

1. 1

   Cross-reference the requested parameter index from the PLC/HMI program with the inverter's official parameter manual (version-specific) to identify the correct parameter address (e.g., verify P0-01 is correct).

2. 2

   Verify the integrity and correctness of the parameter mapping table (e.g., Modbus register map, Profinet GSDML file mapping) within the fieldbus master device configuration.

3. 3

   Confirm that the firmware version of the inverter matches the firmware version used for generating the parameter documentation or PLC programming.

4. 4

   Modify the PLC/HMI program to access only valid and documented parameter indices for the specific inverter model and firmware (e.g., changing register 40003 to 40001 if 40003 is undefined).
