Parameter Checksum Error
Allen-Bradley · PowerFlex 40 Adjustable Frequency
¿Qué significa F100 ?
This fault indicates an inconsistency or corruption in the drive's parameter memory (EEPROM). This can happen due to unexpected power cycling or internal memory issues, requiring a restoration of default settings.
Causas comunes
- Sudden loss of power or unexpected power cycling during a parameter write operation to the drive's EEPROM.
- Internal EEPROM memory corruption due to age, manufacturing defect, or exposure to excessive electrical noise.
- Firmware incompatibility or a bug that leads to incorrect checksum calculation during parameter storage.
- Environmental factors such as extreme temperature fluctuations or high levels of vibration affecting internal memory components.
Pasos de reparación & Lista de verificación

- 1
Reload the saved parameter configuration file into the drive using a software tool like Connected Components Workbench.
- 2
Perform a power cycle of the drive (turn off main power for 30 seconds, then reapply) to clear any transient memory errors.
- 3
Check the incoming supply voltage for stability and adherence to specifications using a true RMS voltmeter. Address any power quality issues.
- 4
If the fault persists after reloading parameters, attempt a factory reset (e.g., setting P0-53 [Reset to Defaults] to a specific value) and then reload parameters.
- 5
If the checksum error reoccurs, the drive's internal EEPROM or memory board is likely faulty, and the drive unit requires replacement.
