A concise guide for selecting SINAMICS S120 drive modules, power units, motor modules, and accessories.
About this manual
This document provides a quick‑reference selection guide for the SINAMICS S120 family of AC/AC drives. It lists available power modules (ALM, SLM, BLM), motor modules, control units, brake units, and the required Drive‑CLiQ cables and adapters, with part numbers and typical ratings.
The guide explains the step‑by‑step selection process: choose a motor module based on rated current, decide on encoder feedback and the appropriate Drive‑CLiQ cable, select a compatible power module considering overload and grid conditions, and finally pick a control unit (CU320, CU310, etc.) with the needed CF‑card and operator panel. It also covers brake unit and resistor choices for different module types. This manual is written in Chinese.

Frequently asked questions
How many axes can a CU320 control?
One CU320‑2DP can control up to six servo axes, four vector axes, and five position axes (or twelve V/F axes).
What brake unit is required for book‑size S120 modules?
Book‑size S120 DC/AC drives require a brake unit directly connected to the DC bus, with each brake unit paired with its corresponding brake resistor.
