Servo Controller | Siemens | 6SL3120-2TE21-0AA4 6SL3 120-2TE21-0AA4 SINAMICS S120 Double Motor

Product Description: Siemens 6SL3120-2TE21-0AA4

The Siemens 6SL3120-2TE21-0AA4 is a double motor module from the SINAMICS S120 series, designed to control two independent servo or induction motors in compact multi-axis drive applications. Each output channel supports up to 3 A continuous current from a 600 V DC link, and the module belongs to the Booksize Frame Size B class with internal air cooling. This motor module is used in conjunction with a SINAMICS S120 line module and control unit (CU) via DRIVE-CLiQ interface, making it ideal for dynamic and space-efficient solutions in machine tools, packaging systems, and handling applications.

Key Features

• Dual-Axis Motor Control: Operates two motors independently (3 A each).
• High-Speed Servo Performance: Supports precise torque, speed, and position control.
• Compact Design: Booksize format enables dense panel mounting with minimal footprint.
• DRIVE-CLiQ Interface: Ensures fast, synchronized communication with the control unit.
• Internal Cooling: Equipped with a fan for integrated air cooling.
• Full Integration: Works seamlessly within the SINAMICS S120 modular architecture.
