6SL3120-1TE31-3AA3 Description

6SL3120-1TE31-3AA3 Features

• High-Performance, Modular Drive:​ Part of the scalable SINAMICS S120 system, offering high dynamic response, precision, and flexibility for complex multi-axis applications.
• Common DC Link Operation:​ Designed to be powered from a shared DC bus, which is supplied by a central infeed module. This allows for efficient energy sharing between axes (e.g., braking energy from one motor can be used by another).
• DRIVE-CLiQ Communication:​ Uses the proprietary, high-speed DRIVE-CLiQ interface for communication with the Control Unit. This simplifies wiring, enables automatic drive configuration (topology detection), and provides extensive diagnostic data.
• Wide Power & Voltage Range:​ Covers a broad range of power ratings; this specific model is a 3A unit. Designed for a standard 3-phase 400-480V AC input network via the DC link.
• Advanced Motor Control:​ Supports a wide range of motors (induction, synchronous) and advanced control functions like V/f control, sensorless vector control (SLVC), and closed-loop vector control with an encoder (required for servo operation).
• Integrated Safety (Option):​ Can be equipped with the Integrated Safety(Integrated Drive Control) option, providing Safety functions like Safe Torque Off (STO), Safe Stop 1 (SS1), and Safely-Limited Speed (SLS) without additional hardware.
• Compact & Efficient Cooling:​ Booksize compact design for space-saving cabinet installation. Features efficient heatsink cooling. An optional Cooling Unit is available for forced-air cooling in high ambient temperatures or high-duty cycles.

6SL3120-1TE31-3AA3 Materials, Construction & Applications

• Materials:​ The housing is a rugged, lightweight aluminum alloy, serving as both structure and heatsink. Power semiconductors (IGBTs) and control electronics are based on advanced SMD technology. The fan (if present) is a long-life, low-noise DC fan.
• Construction:​ Modular, fan-cooled, compact metal chassis designed for side-by-side mounting on a heatsink or cabinet mounting plate. All connections (power, DRIVE-CLiQ, encoder) are via pluggable, front-mounted connectors for easy installation and service.
• Primary Applications:
  • Machine Tools:​ Spindle drives, feed axes, and auxiliary drives for milling machines, lathes, and grinders.
  • Packaging & Printing:​ Drives for web tension control, cut-to-length, printing cylinders, and conveyor synchronization.
  • Material Handling:​ Control of conveyor belts, hoists, cranes, and automated storage/retrieval systems.
  • Test Benches & Simulators:​ High-dynamic applications requiring precise speed and torque control.
  • Any multi-axis machine​ requiring coordinated motion, high dynamics, and energy-efficient operation via a common DC bus.
