Parameter Setting Out of Range

What does oPE02 mean?

One or more drive parameters have been set to a value that falls outside their permissible setting range. This prevents the drive from accepting the configuration and can lead to operational issues or prevent the drive from starting.

• Manual entry of a parameter value (e.g., maximum frequency A1-04) that exceeds its defined upper limit or falls below its lower limit.
• Parameter group copy/paste from another drive model with different parameter ranges.
• Attempting to set interdependent parameters (e.g., A1-04 max frequency vs E1-04 V/f reference frequency) where one value restricts the other.
• Firmware version incompatibility with an uploaded parameter file, causing some parameters to be out of range for the current firmware.

Click steps to track your progress.

1. 1

   1. Identify the specific parameter(s) triggering the fault, often indicated on the drive display or via fault log.

2. 2

   2. Consult the drive's programming manual for the identified parameter(s) to determine their allowed setting range.

3. 3

   3. Adjust the parameter(s) to a value within the specified permissible range.

4. 4

   4. If multiple parameters are involved, check for interdependencies (e.g., ensure A1-04 is greater than A1-03, and E1-04 is less than or equal to A1-04).

5. 5

   5. Perform a parameter initialization (Parameter A1-03 to '2' or similar) if a wide range of settings appear incorrect (note: this will reset all parameters to factory defaults).
