Parameter Maximum Value Exceeded

What does 10 mean?

An attempt was made to set a parameter's value above its defined maximum limit. This prevents system operation outside safe or intended bounds, crucial for equipment longevity and safety. If the new value is critical, the parameter limits must be expanded.

• A PLC program is attempting to write a value to a parameter (e.g., P2-01, Motor Speed Reference) that exceeds its configured maximum limit (e.g., P2-03, Maximum Speed).
• Manual entry via the drive keypad or HMI resulted in a value higher than the parameter's absolute hardware or firmware-defined maximum.
• An analog input signal (e.g., AI1 connected to terminal 5) is scaled incorrectly, causing the resulting parameter value to exceed its maximum threshold (e.g., P7-03 scaling for AI1).
• A computed value from a controller attempts to set a parameter above its physically or safely allowable maximum (e.g., setting Motor Current Limit P4-02 above rated motor current).

Click steps to track your progress.

1. 1

   1. Identify the parameter being written to and read its configured maximum limit (e.g., check P2-03 for P2-01, or the absolute maximum from the manual).

2. 2

   2. Adjust the PLC program logic or HMI input fields to ensure that the value written to the parameter is always less than or equal to its maximum limit.

3. 3

   3. Verify the scaling configuration for any analog input (e.g., P7-03 for AI1) that influences the parameter's value to ensure proper mapping within the acceptable range.

4. 4

   4. If manual entry, ensure the operator is aware of the maximum limit for the parameter and provides a value below it.
