No Value In List

What does 11 mean?

The system attempted to select a value for a list-type parameter that is not available in its predefined list of options. This typically occurs when a discrete parameter is assigned an undefined enumeration value, leading to an invalid configuration.

• A PLC program or HMI is attempting to set a list-type parameter (e.g., P5-01, Motor Control Mode) to an integer value that is not defined in its enumeration list (e.g., trying to set P5-01 to '5' when valid options are 0-3).
• Incompatible firmware versions where the enumeration options for a specific parameter have changed, and the PLC program is still using an outdated value.
• Typographical error in a configuration file or HMI dropdown selection mapping that results in an undefined option being chosen.

1. 1

   1. Consult the drive's parameter manual to identify all valid enumeration options (e.g., 0=V/F, 1=Sensorless Vector) for the specific list-type parameter (e.g., P5-01).

2. 2

   2. Modify the PLC program or HMI configuration to ensure that only the predefined, valid integer values are written to the list-type parameter.

3. 3

   3. If using an HMI, verify that the dropdown list or selection buttons are correctly mapped to the integer values specified by the drive.

4. 4

   4. Check for firmware compatibility issues; if the drive's firmware has been updated, ensure the application logic reflects any changes to parameter enumeration values.
