6SL3121-1TE24-5AA3

Siemens offers the 6SL3121-1TE24-5AA3 motor module as part of its SINAMICS S120 series, designed for reliable motor control applications. This unit functions within a DC link voltage range from 510 to 720 VDC, suitable for high-performance environments. The electronics of this module operate at a supply voltage of 24 VDC and have a maximum current demand of 1.2A.

In operation, the module provides a rated output current of 45A, with the ability to handle a maximum output of 85A during demanding conditions. When in normal running scenarios, the output base load is typically 38A, demonstrating its capacity for sustained performance. The motor module also features a rated pulse frequency of 4 kHz to facilitate efficient control over motor functions.

To accommodate connections within its framework, the DC link busbars are rated for 200A, while the 24V current carrying busbar supports up to 20A. With a capacitance of 1175 microfarads, the DC link capacitance allows for effective energy storage and management. The cooling mechanism operates via external air, ensuring the device remains within the optimal temperature range of 0 to 40 degrees Celsius.

It is worth noting that the maximum length for shielded motor cables can extend to 100 meters (328 feet), while unshielded cables can reach up to 150 meters (492 feet). This flexibility in cable length eases installation and integration in various setups, making this motor module highly adaptable for numerous industrial applications.
