Siemens A30057 fault code meaning

Series: G110M, G115D, G120C, G120D, G130-G150, S120-S150

Power unit: Power supply imbalance

converter

Meaning: A frequency component in the DC bus voltage indicates power supply asymmetry or power supply phase loss, or possibly motor phase loss. Fault F30011 is output no later than 5 minutes after this alarm occurs. The exact time depends on the power unit type and the respective frequency. For Booksize and Chassis power units, the time also depends on how long the alarm has already been present.

Series: G120-CU240B-E-2, G120-CU250S-2

Power unit: Power supply imbalance

converter

Meaning: Supply imbalance or supply phase loss was detected from a frequency component of the DC bus voltage. Motor phase loss is also possible. Fault F30011 is output no later than 5 minutes after this alarm occurs. The exact time depends on the power unit type and the respective frequency. For Booksize and Chassis power units, the time also depends on how long the alarm has already been present.

Series: G120X, G120XA

Power unit: Power supply imbalance

converter

Meaning: Power supply asymmetry, power supply phase loss, or possibly motor phase loss was detected from a frequency component of the DC bus voltage. Fault F30011 is issued no later than 5 minutes after this alarm occurs. The actual time depends on the power unit type and the respective frequency. For Booksize and Chassis power units, the time also depends on how long the alarm has already been present.

Series: G200, G210, G210X, G220, S220

Power unit: Mains imbalance

converter

Meaning: Abnormal frequencies have been detected in the DC bus voltage, indicating possible mains imbalance or phase loss. A motor phase may also be missing. If these frequencies persist with the same or greater amplitude, fault F30011 is issued after a device-specific time.

Series: S200

Power unit: Power supply imbalance

servo drive

Meaning: A frequency component in the DC bus voltage indicates power supply asymmetry, mains phase loss, or possibly motor phase loss. If these frequency components persist with the same or greater amplitude, fault F30011 is output after a device-specific time. The alarm value is intended only for internal Siemens fault diagnostics.

Series: S210

Power unit: Power supply imbalance

servo drive

Meaning: A frequency component in the DC bus voltage indicates power supply asymmetry, power supply phase loss, or possibly motor phase loss. If these frequency components persist with the same or greater amplitude, fault F30011 is output after a device-specific time. The alarm value is intended only for internal Siemens fault diagnostics.
