Key Information
This AA3 Single Motor Module is designed for one motor axis in a booksize SINAMICS S120 drive line-up. It participates in the common DC-link and DRIVE-CLiQ architecture while using a cold-plate interface rather than an internal or external air-cooling path. The complete suffix must be retained because similarly rated air-cooled and later hardware variants are separate articles.

Functions
- Converts common DC-link power into a controlled three-phase motor supply for one axis.
- Implements optimized pulse patterns for the documented module generation.
- Carries control, identification and diagnostic information through DRIVE-CLiQ.
- Provides the power hardware used by Extended Safety Integrated functions in a validated system.
- Transfers its principal heat load through the engineered cold-plate interface.

Installation
- Engineer the cold-plate assembly for the module loss profile and use the manufacturer-defined mounting interface.
- Observe the DC-link assembly sequence, protective-earth connection and service clearances for booksize components.
- Confirm that motor cables, connectors and upstream line-up components suit the selected current class.
- Match the control-unit firmware, DRIVE-CLiQ topology and safety project to the full AA3 reference.
- Commission under controlled conditions and monitor thermal and diagnostic behavior before production use.
05 /
Lifecycle
- The official Siemens portal identifies this exact reference as an Active Product.
- AA3 and AA4 endings must not be collapsed into a generic stock description.
- Retain an approved project backup and the original commissioning records with the machine documentation.
- Record the cold-plate arrangement as part of the service specification, not only the electrical rating.
- After exchange, test motor direction, load response, diagnostics and safety functions.
