The Siemens S120 commissioning manual provides product overview, configuration, wiring, diagnostics and troubleshooting information.
The manual introduces the SINAMICS S120 drive family, describing its system composition for both DC‑AC and AC‑AC types, typical control loops, and the modules that make up a drive system such as the CU320 control unit, power modules (BLM, SLM, ALM), motor modules and the DRIVE‑CLIQ interface. It also explains the power ranges (0.9 kW‑1200 kW for DC‑AC, 0.12‑250 kW for AC‑AC) and the capabilities of the CU320 and CU320‑2 control units.
Detailed wiring rules for the DRIVE‑CLIQ bus are provided, including node limits, recommended connections, and special considerations for single‑ and double‑axis motor modules. The appendix lists related reference manuals and contact information for Siemens support. This manual is written in Chinese.
| DC‑AC Power Range | 0.9 kW to 1200 kW |

| DRIVE‑CLIQ Max Nodes per Connection | 16 nodes |
| DRIVE‑CLIQ Max Nodes per Row | 8 nodes |
| CU320 Servo Axis Capacity | 6 servo axes |
| CU320 Vector Axis Capacity | 4 vector axes |
A single DRIVE‑CLIQ connection can link up to 16 nodes, with a maximum of 8 nodes per row, and loops are not allowed.
The DC‑AC version of the S120 drive covers power ratings from 0.9 kW up to 1200 kW.
