Parameter Checksum
Allen-Bradley · PowerFlex 4M Adjustable Frequency AC Drive
What does F100 mean?
An inconsistency has been detected in the drive's parameter memory; the calculated checksum of stored parameters does not match the expected value. This suggests potential data corruption in the non-volatile memory (EEPROM), which could lead to erratic drive behavior due to incorrect parameter settings.
Complete Troubleshooting Guide
- 1
Power cycle the drive and then set parameter P112 [Reset To Defalts] to option 1 'Reset Defaults' to force the drive to reload factory default parameters.
- 2
After resetting to defaults, re-program all necessary drive parameters according to your application specifications.
- 3
If the fault reoccurs after multiple resets and re-programming, it may indicate a deeper hardware issue with the drive's memory, potentially requiring drive replacement.
