Parameter Checksum Error

What does F100 mean?

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.

• 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.

Click steps to track your progress.

1. 1

   Reload the saved parameter configuration file into the drive using a software tool like Connected Components Workbench.

2. 2

   Perform a power cycle of the drive (turn off main power for 30 seconds, then reapply) to clear any transient memory errors.

3. 3

   Check the incoming supply voltage for stability and adherence to specifications using a true RMS voltmeter. Address any power quality issues.

4. 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. 5

   If the checksum error reoccurs, the drive's internal EEPROM or memory board is likely faulty, and the drive unit requires replacement.
