The 6SL3120-1TE28-5AA3 is a booksize form-factor single motor module within the SINAMICS S120 motion control system, formulated for multi-axis synchronization and high-dynamic automated drive layouts. Operating within an industrial electrical network topology, this hardware relies on an external common DC-link power structure fed by a front-end Line Module rather than direct grid connectivity. It accepts a rated DC-link input voltage spanning from 510V to 720V DC, alongside a dedicated 24V DC auxiliary electronics power supply that tolerates a fluctuations margin of -15% to +20%, drawing a maximum control current of 1.50 A.
Utilizes a booksize compact form factor with a physical width of 200 mm
Embeds a highly reliable functional safety monitoring sub-circuit inside the module
Integrates 3 sets of proprietary, high-speed DRIVE-CLiQ serial communication slots on the front of the module
Regarding the electrical connections and functional safety architecture, the unit adheres to a compact Booksize cabinet format with an IP20 / UL open-type ingress protection rating. For robust electrical integration, the common DC-link copper busbars possess a continuous current-carrying capacity of 200 A, while the secondary 24V control busbars accommodate up to 20 A. The motor-end connection (X1) utilizes robust M8 bolt terminals that accept heavy-duty cable cross-sections, paired with a dedicated M6 screw for PE ground bonding.
Field cable routing limits are governed by strict capacitance criteria, allowing a maximum shielded motor cable length of 100 meters or an unshielded cable length of 150 meters. The unit complies with CE and cULus regulatory frameworks and embeds integrated safety functions certified to international industrial criteria, satisfying Functional Safety Integrity Level 2 (SIL 2) according to IEC 61508, Performance Level d (PL d) pursuant to EN ISO 13849-1, and Category 3 hardware architecture limits.

Machine Tool Manufacturing
High-speed milling and turning spindle axes. Regulates the 85A continuous power delivery to primary synchronous or asynchronous spindle motors, ensuring smooth vector control speed stability up to 300 Hz.
Automotive Assembly
Multi-axis articulated robot joints and welding line positioning. Synchronizes rapid accelerate/decelerate movements on high-inertia heavy-payload robot positioning structures using its common DC link configuration to recycle braking energy.
Semiconductor & Electronics Packaging
High-speed pick-and-place gantry axes. Executes sub-millisecond precision servo loop timing over DRIVE-CLiQ networks to facilitate precise wafer handling or printed circuit board component placement.
Plastics & Rubber Extrusion
Continuous melt pump and heavy-duty twin-screw extruder drives. Supplies high continuous current torque output under closed-loop vector control to guarantee consistent volumetric output and material density stability.
Lithium-Ion Battery Production
Continuous roll-to-roll electrode coating and slitting tension control. Maintains highly sensitive, micro-Newton web tension profiles across copper or aluminum foils to prevent substrate stretching, wrinkling, or breaking.
It must be secured vertically to a metal backplate, forming a stable side-by-side common busbar connection with adjacent modules via its top integrated copper bars, while ensuring the cooling air path satisfies the physical airflow requirement of 160 m³/h. A compatible external Control Unitand the DRIVE-CLiQ digital network must be properly connected prior to field operation, and the current boundaries for rated continuous, intermittent, and transient peak maximum loads must be rigidly cross-checked. Due to the built-in 1,880 µF large-capacity capacitance, a minimum discharge wait time of 5 minutes is mandatory after isolating the front-end main power before executing any physical inspections on the wiring terminals.
