Siemens SINAMICS 6SL3210-1PE23-3AL0 Power Module PM240-2

Product Overview

The Siemens 6SL3210-1PE23-3AL0 (6SL32101PE233AL0) is a high-performance SINAMICS PM240-2 Power Module designed for modular drive systems. Engineered for precision motor control, this Frame Size C (FSC) module features an integrated Class A line filter and a built-in braking chopper, making it an ideal choice for applications involving regenerative energy and strict EMC requirements. Whether in pump, fan, or conveyor systems, the 6SL3210-1PE23-3AL0 provides robust power conversion for 3-phase asynchronous and synchronous motors. Its dual-overload rating system—supporting 11 kW for High Overload and 15 kW for Low Overload—allows engineers to optimize the drive's performance based on specific dynamic requirements, ensuring maximum system uptime in demanding industrial environments.

Technical Configuration

The 6SL3210-1PE23-3AL0 represents the latest generation of Siemens power electronics, focused on efficiency and modularity.

• Integrated EMC Filtering: The built-in Class A filter ensures compliance with industrial electromagnetic compatibility standards, reducing interference with sensitive electronics.

• Dynamic Braking: An integrated braking chopper allows for the connection of an external braking resistor, facilitating rapid deceleration of high-inertia loads.

• Modular Interface: Designed to be paired with a SINAMICS Control Unit (CU) and Basic/Intelligent Operator Panel (BOP/IOP). It is compatible with CU firmware version V4.6 and higher.

• Advanced Cooling: Utilizes an efficient heat sink design with a variable-speed fan to maintain optimal operating temperatures while minimizing acoustic noise.

• Protection Circuitry: Features comprehensive monitoring for overvoltage, undervoltage, ground faults, and short circuits at the output terminals.

Technical Specifications

Technical FAQs

Does this power module include a Control Unit?

No, the 6SL3210-1PE23-3AL0 is a power stage only. To function, it must be combined with a SINAMICS Control Unit such as a CU240E-2 or CU250S-2.

What is the difference between High Overload (HO) and Low Overload (LO) for this module?

High Overload (11 kW) is for applications requiring high starting torque (200% for 3s). Low Overload (15 kW) is suitable for continuous torque applications like centrifugal pumps or fans where only 110% overload is needed for 57s.

Can I use this module without a braking resistor?

Yes, but if your application requires fast braking or involves an overhauling load, the DC link voltage may rise and trigger an overvoltage fault. In such cases, an external braking resistor must be wired to the module's R1/R2 terminals.

Engineering & Installation Guide

• EMC Compliance: Since this module has a built-in Class A filter, ensure that the motor cable is shielded and the shield is grounded at both the module end (using the provided shielding plate) and the motor terminal box to prevent high-frequency interference.

• Airflow Requirements: The PM240-2 FSC requires adequate ventilation. Maintain a minimum clearance of 100 mm above and below the unit. Do not install the module directly above heat-producing components like braking resistors or reactors.

• Braking Resistor Connection: When wiring an external braking resistor, use heat-resistant cables. Ensure the resistor is mounted outside the drive cabinet if possible, or in a well-ventilated area, as it will dissipate significant heat during braking cycles.
