The Siemens S120 fault and alarm manual explains fault/alarm definitions, actions, confirmation methods and troubleshooting steps.
This manual provides an overview of the fault and alarm system for the SINAMICS S120 drive. It describes how faults and alarms are generated, displayed via PROFIBUS or test software, and the differences between fault and alarm actions.
It also details the fault actions, confirmation procedures (power‑up, parameter settings, BINECTOR inputs, PROFIBUS signals), storage of fault data in the non‑volatile buffer, and the measures required to clear or resolve faults and alarms. This manual is written in Chinese.
