Siemens 6SL3126-1TE21-8AA4 SINAMICS S120 Single Motor Module

Description

The 6SL3126-1TE21-8AA4 is a SINAMICS S120 single motor module designed for high-performance motion control applications within industrial automation systems. This Booksize format module operates with a DC input voltage range of 510–720V (nominal 600V) and delivers a 3-phase AC output of 400V with a nominal output current of 18A. Engineered for thermal efficiency in compact installations, the unit utilizes cold-plate cooling, allowing heat to be dissipated through the mounting surface, which is ideal for space-constrained control cabinets. The module also features an optimized pulse sample system and supports extended Safety Integrated functions, providing advanced protection and operational reliability in complex machine environments. It is supplied with a DRIVE-CLiQ cable for seamless integration into Siemens drive architectures.

• Industrial robotics and automated handling equipment.
• Machine tool drives and production line automation.
• High-dynamic processes requiring integrated safety functions.

Technical Specifications

Installation Guidelines

• Mounting: Ensure the cold-plate surface is perfectly flat and clean to maximize thermal transfer; use thermal conductive paste if required.
• Grounding: Establish a low-impedance connection to the cabinet frame to ensure electromagnetic compatibility (EMC).
• Wiring: Route power and signal cables separately to prevent signal interference; use the included DRIVE-CLiQ cable for control communication.
• Safety: Verify that all Safety Integrated functions are correctly commissioned and tested according to site-specific safety protocols.
• Ventilation: Although cold-plate cooled, ensure adequate ambient airflow within the cabinet to manage non-contact thermal dissipation.
