Description
Product Overview
6SL3210-1SE27-5AA0 is a blocksize air-cooled PM340 power module for the Siemens SINAMICS S120 high-performance drive system, equipped with an integrated EMC line filter. It converts 3-phase AC mains power to variable-frequency AC output to drive synchronous or asynchronous motors. This power module must work together with an S120 control unit (CU320) to realize speed, torque and position closed-loop control for single-axis motion applications.

Key Features
- Built-in EMC Line Filter: Integrated mains filter simplifies cabinet layout and meets EMC requirements without an external filter.
- High Power Density Block Design: Compact block form factor for standard electrical cabinet installation.
- Comprehensive Hardware Protection: Overcurrent, overvoltage, undervoltage, phase loss, over-temperature, short-circuit and earth fault protection. Fault codes stored for diagnostics.
- High Dynamic Motor Control: Supports asynchronous induction motors and permanent magnet synchronous servo motors for demanding motion tasks.
- Modular S120 Architecture: Works with CU320 control unit; supports high-speed encoder feedback and PROFIBUS / PROFINET communication.
- Built-in DC link pre-charge circuit: Smooth power-up process to suppress inrush current on power-on.
Applications
- Heavy-duty CNC machine tools and metal forming machinery
- Printing, paper and textile production lines
- Metallurgical processing lines and large material handling gantries
- Packaging machinery with high dynamic motion requirements
- Conveyors, test benches and high-performance single-axis automation
Installation & Maintenance Notes
- Implement lockout-tagout before opening the unit. DC link capacitors retain dangerous high voltage long after AC power is disconnected.
- Maintain sufficient cabinet ventilation. Clean cooling fan and heat sink dust periodically to prevent overheating.
- Separate motor power cables from encoder and communication signal cables to reduce EMI interference.
- Match control unit firmware and motor parameters during commissioning via STARTER or TIA Portal.
- Inspect terminal tightness, fan running status and thermal hotspots during routine maintenance.
- Verify full part number match when replacing spare module, confirm integrated filter version.
FAQ
Q: What does suffix “5AA0” stand for? A: 5AA0 = blocksize PM340 with integrated EMC line filter.
Q: Can PM340 run independently without CU320 control unit? A: No. PM340 is only the power stage; a CU320 control unit is mandatory to execute drive control logic.
