Siemens A31442 fault code meaning

Series: G120-CU240B-E-2

Encoder 1: Battery voltage prewarning

converter

Meaning: When power is off, the encoder uses a battery to retain multi-turn information. If battery power is insufficient, the encoder cannot continue to retain multi-turn information.

Possible causes

Source: SINAMICS G120, Control Unit CU240B-2_CU240E-2 P787

Series: G120-CU250S-2

Encoder 1: Battery voltage prewarning

converter

Meaning: When power is off, the encoder uses a battery to retain multi-turn information. The battery power is insufficient, so the encoder cannot continue to retain multi-turn information.

Possible causes

Source: SINAMICS G120, Control Unit CU250S-2 P1516

Series: G130-G150, S120-S150

Encoder 1: Battery voltage alarm threshold reached

converter

Meaning: When power is off, the encoder uses a battery to retain multi-turn information. If battery power is insufficient, the encoder cannot continue to retain multi-turn information.
