Siemens 6SL3120-2TE21-0AA4 Double Motor Module

The Siemens 6SL3120-2TE21-0AA4 SINAMICS Double Motor Module is a two-axis drive module for SINAMICS S120 systems that delivers synchronized control of two servo motors in high-performance motion applications. It provides two motor outputs with a 600 V DC link input, approximately 9 A per axis, and uses Servo/Vector Control for precise, dynamic motion, all inside an internal-air-cooled, IP20-rated enclosure. Mounted in booksize format for drive system integration, it communicates via the SINAMICS Drive System Bus and supports operation from 0 to 40°C. Commonly used in CNC machines, machine tools, robotics, packaging lines, converting machinery, and other high-speed production lines requiring coordinated dual-axis motion; common replacements include Siemens 6SL3120-2TE21-8AA3, 6SL3120-1TE21-0AA4, and 6SL3120-2TE15-0AA3.
