FAQs

Q1: What is the primary function of the 6SL3210-1SE16-0UA0?
It is a PM340 Power Module for the SINAMICS S120 modular drive system. It converts AC line power to controlled DC power for the motor and works in conjunction with a separate Control Unit (CU310-2 or CU320-2) that provides the closed-loop control and communication functions.
Q2: Is this module still available for purchase?
It is available as a spare part only. The product was cancelled by Siemens on October 1, 2019 (PM410 status) . New units are no longer manufactured. Spare parts and refurbished units may be available through aftermarket suppliers. Siemens has not provided a direct successor for this specific Blocksize PM340 module.
Q3: Does this module require a Control Unit?
Yes. The 6SL3210-1SE16-0UA0 is a Power Module only. A compatible Control Unit (such as CU310-2 PN for single-axis or CU320-2 PN for multi-axis applications) must be ordered separately. The Control Unit determines the communication protocols and safety functions available.
Q4: Does this module have an integrated line filter?
No. The "U" in the model number indicates an unfiltered version. For applications requiring an integrated Class A line filter, the 6SL3210-1SE16-0AA0 variant should be selected. Unfiltered versions are suitable for connection to grounded TN/TT and ungrounded IT systems.
Q5: What are the common applications for this module?
The PM340 Power Module is used in modular machine concepts requiring precise motion control, such as machine tools, packaging machines, printing presses, and production machinery. The 2.2 kW power rating makes it suitable for small to medium-sized servo and induction motors in multi-axis configurations.
