Siemens F05118 fault code meaning

Series: G110M, G115D

Precharging contactor synchronization monitoring time exceeded

converter

Meaning: A feedback signal has been interconnected for the precharging contactors (ALM, SLM, BLM diode) or power supply contactors (BLM thyristor), and synchronization monitoring has been activated (p0255[4, 6]). After the contactors in the parallel circuit are opened or closed, they do not all reach the same status by the end of the monitoring time.

Series: G120-CU250S-2

Precharging contactor synchronization monitoring time exceeded

converter

Meaning: %1, Additional information: %2. Drive object: CU250S_V, CU250S_V_CAN, CU250S_V_DP, CU250S_V_PN. Reaction: OFF2 (OFF1, none). Acknowledgment: Immediate (power-on). Cause: Feedback has been interconnected for the precharging contactor (ALM, SLM, BLM diode) or power supply contactor (BLM thyristor), and synchronization monitoring has been activated (p0255[4, 6]). After the contactors in the parallel circuit are opened or closed, not all contactors reach the same status before the monitoring time expires.
