SIEMENS 6SL3210-1PE28-8AL0 SINAMICS G120 Power Module

 

 

The SIEMENS 6SL3210-1PE28-8AL0 is a SINAMICS G120 PM240-2 Power Module, used as the main power stage of a variable frequency drive (VFD).

Product Information

• Brand: Siemens
• Series: SINAMICS G120
• Model: 6SL3210-1PE28-8AL0
• Type: Power Module (PM240-2)
• System: G120 modular drive system
• Supply voltage: 3AC 380–480V
• Frequency: 47–63 Hz
• Function: Converts AC power → controlled output for motor speed/torque control
• Built-in features: Line filter (Class A) + braking chopper
• Output power: approx. 37 kW (high overload) / 45 kW (low overload) class

What it actually is

This is NOT a PLC or control module.

It is the power hardware stage of a VFD system, meaning:

• It handles all motor power switching
• It generates variable frequency output for AC motors
• It is controlled by a separate Control Unit (CU240 / CU250 etc.)

System Role (Simple)

Control Unit (CU240E-2 / CU250)
→ sends control signals
→ PM240-2 Power Module (this unit)
→ outputs variable frequency 3-phase power
→ AC motor runs at controlled speed

Key Features

• High-power 3-phase AC motor control (VFD power stage)
• Built-in braking chopper for energy dissipation
• Integrated Class A line filter (reduces EMI noise)
• Modular design (separate control unit + power module)
• High overload capability for heavy industrial loads
• Designed for harsh industrial environments

Typical Applications

• Conveyor systems
• Pumps and compressors
• Fans and HVAC systems
• Industrial machinery
• Production lines
• Heavy-duty motor speed control systems

Advantages

• High efficiency motor speed control
• Strong overload capacity for startup loads
• Modular repair concept (replace CU or power stage separately)
• Built-in braking support (no external chopper needed in many cases)
• Robust Siemens industrial design

Important Notes

• Not a PLC ❌
• Not a communication module ❌
• Not a standalone drive ❌
• It is a VFD power module (needs control unit to operate) ✔
• Cannot run motor alone without CU (Control Unit required)

Precautions

• Must be matched with correct SINAMICS G120 Control Unit
• High voltage DC link inside → danger even after power off
• Proper grounding and EMC wiring required
• Incorrect parameterization via CU may damage motor
• Cooling/ventilation required in cabinet installation
