More Information

Overview Manuals Duty Selection Installation Limits Connections & EMC Product Applications

Features:

  • Filtered power stage: Uses an integrated Class A line filter for the specified SINAMICS G120 installation.
  • Overload flexibility: Provides separate low-overload and high-overload ratings for different load profiles.
  • Dynamic braking: Includes the braking chopper needed to switch a correctly sized external resistor.
This article is the motor power stage; control and operator functions are supplied separately through the selected SINAMICS components.

Duty selection should follow operating current, acceleration demand and cycle timing instead of motor power alone.

Cabinet cooling, motor-cable length, grounding and braking-resistor sizing remain installation-level decisions.

Apter Power supports Siemens 6SL3210-1PE21-1AL0 PM240-2 sourcing with quotations, official documentation and SINAMICS G120 configuration matching.

Important Notice: The PDF and internal resources support product identification, installation planning and configuration review.
  • Line input: Match a 3 AC 380–480 V ±10% supply at 47–63 Hz.
  • Low-overload duty: Use the 4 kW and 10.2 A rating only with the stated 110% and 150% overload cycle.
  • High-overload duty: Use the 3 kW and 7.7 A rating where the stated 150% and 200% overload cycle is required.
  • Peak current: Keep the operating profile within the 15.4 A maximum output current.
  • Enclosure: Treat the IP20 / UL open-type module as protected cabinet equipment.
  • Cooling: Preserve the internal-air-cooling path and the specified 0.009 m³/s airflow.
  • Temperature: Apply the -10 to +40°C LO limit or -10 to +50°C HO limit for the selected duty.
  • Altitude: Use 1,000 m as the published installation-altitude reference before checking any required derating.
  • Power terminals: Accept 1.5–6 mm² conductors for both line and motor connections.
  • Shielded cable: Keep the motor lead within the published 50 m maximum.
  • Unshielded cable: Keep the motor lead within the published 100 m maximum.
  • EMC boundary: Complete cabinet bonding, shield termination and grounding even though the module has an integrated Class A filter.
  • Conveyors: Evaluate high-overload duty where starting torque and repeated acceleration dominate the cycle.
  • Pumps and fans: Evaluate low-overload duty only after the load curve and operating current are confirmed.
  • Braking loads: Coordinate the integrated chopper with a resistor sized for regenerated energy and stop frequency.
  • Retrofit panels: Match the FSB format, line supply, Control Unit, motor cable and cooling arrangement before exchange.
Description
Siemens 6SL3210-1PE21-1AL0 is the filtered FSB PM240-2 power stage for SINAMICS G120 drives supplied from 3 AC 380–480 V. It converts line power for the motor and provides an integrated braking chopper for applications that return energy during deceleration.

Engineers can rate 6SL3210-1PE21-1AL0 at 4 kW and 10.2 A for low-overload duty or 3 kW and 7.7 A for high-overload duty. The correct choice follows actual acceleration, peak torque and cycle timing rather than motor nameplate power alone.

For retrofit work, 6SL3210-1PE21-1AL0 should be selected against the installed line supply, duty profile, motor, braking resistor and cabinet format. Apter Power can support exact-model quotations, official documentation and configuration matching for planned replacement or new-system sourcing.

Technical notes
Siemens lists 6SL3210-1PE21-1AL0 as approved for Control Unit firmware V4.6 and supplies the power module without a Control Unit or panel. Confirm the installed Control Unit and firmware before replacement so the existing project has a supported commissioning path.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
How should low-overload or high-overload duty be selected for 6SL3210-1PE21-1AL0?
Use the actual acceleration, peak-torque and cycle-time profile: LO permits 4 kW and 10.2 A, while HO permits 3 kW and 7.7 A.
Why can 6SL3210-1PE21-1AL0 trip on overtemperature after installation?
Check cabinet ambient temperature, the internal cooling path, required airflow, switching frequency and any installation derating before replacing the module.
When does 6SL3210-1PE21-1AL0 need an external braking resistor?
The integrated chopper switches regenerated energy, but the resistor must still be selected from the load inertia, deceleration time and braking cycle.
Why can EMC problems remain with the Class A filter in 6SL3210-1PE21-1AL0?
The filter is one part of the installation; shield termination, cabinet bonding, cable routing, grounding and motor-cable length still affect emissions.
Can an existing SINAMICS Control Unit be reused with 6SL3210-1PE21-1AL0?
Reuse only after confirming an approved Control Unit and firmware combination; Siemens identifies V4.6 as approved for this article.
What should be checked before replacing 6SL3210-1PE21-1AL0 after a power-stage fault?
Review line quality, DC-link evidence, motor and cable insulation, braking components, cooling and the stored fault history so an external fault is not carried into the replacement.
