Siemens A07454 fault code meaning
Siemens / A07454
Series: G120-CU250S-2
Position loop: No valid encoder for actual position value processing
converter
Meaning: The following problems occurred during actual position value processing: - No encoder is assigned to actual position value processing (p2502 = 0). - An encoder is assigned, but no encoder data set is assigned to it (p0187 = 99 or p0188 = 99). - An encoder and an encoder data set are assigned, but the encoder data set contains no encoder data (p0400 = 0) or contains invalid data (for example, p0408 = 0).

Position actual value processing has no valid encoding
converter
Meaning: Causes: • No encoder has been assigned for actual position value processing (p2502 = 0). • An encoder has been assigned, but no encoder data set has been configured (p0187 = 99 or p0188 = 99 or p0189 = 99). • An encoder has been assigned and an encoder data set has been configured, but the data set contains no encoder data (p0400 = 0) or valid data (e.g., p0408 = 0).
