The 6SL3120-1TE21-8AC0 is a single-axis motor module for modular motion-control systems using a common DC link architecture. It is designed to supply one compatible three-phase motor with controlled output for servo, vector or V/f drive applications.
This module operates from a 510 to 720 VDC DC link and provides a rated output current of 18 A. It supports up to 36 A maximum output current and is suitable for motion applications requiring responsive motor control, coordinated drive operation and compact cabinet installation.
The unit uses a Booksize C mechanical design with internal air cooling. It includes a DRIVE-CLiQ communication connection for integration with compatible control and power modules. The module also supports extended Safety Integrated functions when used within a correctly configured drive system.
With its narrow 50 mm width, the 6SL3120-1TE21-8AC0 is suitable for multi-axis machinery, packaging equipment, conveyors, machine tools, material handling systems and automated production lines.
