SIEMENS 6SL3120-1TE31-3AA3 Product Description

The SIEMENS 6SL3120-1TE31-3AA3 is a SINAMICS S120 booksize single motor module for high-performance single-axis servo and asynchronous motor drive control in modular multi-axis automation systems. This single motor module adopts 600V DC bus input and provides 3AC 400V, 132A rated output current, supporting internal air cooling and optimized pulse sampling for high dynamic motion tasks. This single motor module integrates DRIVE-CLiQ interface to realize fast digital communication with Siemens servo motors, encoders and other S120 drive components. This single motor module supports extended integrated safety functions, making it suitable for high-demand machinery requiring safe torque off and safe speed monitoring.

This SIEMENS S120 motor module is designed for compact cabinet installation and can be combined with line modules to build a shared DC bus drive system. Its high-performance power IGBT unit converts DC bus power into adjustable three-phase AC output for precise motor torque and speed control. The power IGBT unit uses optimized PWM modulation technology to reduce motor current ripple, acoustic noise and thermal loss during continuous operation. The power IGBT unit integrates complete hardware protection functions including overcurrent, overvoltage, undervoltage and overtemperature protection to prevent permanent component damage. The reliable structure of the power IGBT unit can sustain frequent acceleration and deceleration cycles in high-speed production equipment.

The module supports fast digital signal transmission through DRIVE-CLiQ, automatically identifying motor and encoder data during commissioning to save setup time. Accurate multi-axis motion synchronization realizes coordinated speed, position and torque control for complex production equipment. Stable multi-axis motion synchronization maintains precise master-slave linkage even under dynamic load changes in printing, metalworking and packaging lines. Flexible multi-axis motion synchronization can be configured via STARTER engineering software for parameter tuning, online diagnosis and fault recording. Secure multi-axis motion synchronization works with built-in safety functions to stop movement quickly when safety signals are triggered.

The SIEMENS 6SL3120-1TE31-3AA3 has IP20 protection rating for control cabinet mounting. The booksize form factor enables side-by-side arrangement in the cabinet, saving installation space for multi-axis drive configurations. It supports comprehensive diagnostic functions, recording fault codes and operating history to help maintenance engineers locate wiring, motor or drive faults rapidly. It fully complies with IEC and CE standards and seamlessly cooperates with SINAMICS S120 line modules, control units and HMI panels to form a complete drive system. Widely applied in CNC machine tools, textile machinery, printing equipment, robotic handling and metal forming production lines, this SIEMENS single motor module delivers dependable high-performance single-axis drive capability for modern industrial automation projects worldwide.
