F00055

BOP-EEPROM Fault

Siemens · SINAMICS G120 Variable Speed Drive

What does F00055 mean?

A read or write failure occurred in the EEPROM of the Basic Operator Panel (BOP) during parameter cloning or saving. This could be due to a faulty BOP, an EEPROM that is too small for the stored parameters, or an incompatibility, leading to an inability to store or retrieve non-volatile parameters essential for drive configuration.

Complete Troubleshooting Guide

  1. 1

    Attempt a factory reset of the drive and perform a new parameterization, if possible.

  2. 2

    If r0949 = 5096, replace the BOP with one that has a larger EEPROM capacity.

  3. 3

    If r0949 = 9160, ensure the parameter set being loaded is compatible with the drive's EEPROM capacity, possibly by using a BOP that stores smaller parameter configurations.

  4. 4

    Consider replacing the Basic Operator Panel (BOP) if the fault persists and is not related to EEPROM size.
