F100

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.

Additional Steps

Steps 1–2 are listed in Priority Fix.

  1. 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.
