Value for Parameter Too Large

What does 8.0.00.15 mean?

The value provided for the parameter exceeds its defined maximum permissible limit. This means the requested setting is outside the operational or hardware capabilities for that specific parameter. The parameter value is rejected and not applied.

• A control system (PLC/HMI) attempts to write a speed reference (e.g., P2-01 "Frequency Setpoint") that is higher than the inverter's maximum output frequency limit (e.g., P1-50 "Max Output Freq").
• Attempting to set a motor parameter (e.g., P1-02 "Motor Rated Current") to a value significantly exceeding the inverter's nominal output current or motor's actual rating.
• An acceleration or deceleration ramp time (e.g., P2-05 "Acceleration Time") is set to an excessively high value that exceeds the drive's internal timer limits or maximum configurable range.

Click steps to track your progress.

1. 1

   Consult the inverter's parameter manual for the specific parameter (e.g., P2-01) and identify its defined maximum permissible value.

2. 2

   Review the PLC/HMI program to identify the source of the oversized parameter value and adjust the value to be within the inverter's limits (e.g., cap speed reference at P1-50).

3. 3

   If the desired operational value legitimately exceeds the current limit, adjust the associated limiting parameter (e.g., increase P1-50 "Max Output Freq" if hardware permits).

4. 4

   Verify the data type and scaling used by the PLC/HMI for the parameter write, ensuring it matches the inverter's expected format (e.g., integer vs. float, 0-100% vs. raw counts).
