Parameter Checksum Error

Hva betyr 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.

• 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.

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.
