6SL3210-1PE31-5AL0 is the filtered PM240-2 power stage for modular SINAMICS G120 drive systems. It combines a Class A EMC filter and braking chopper in the FSF enclosure while retaining separate low- and high-overload ratings.

The 75 kW low-overload rating suits variable-torque duties, while the 55 kW high-overload rating supports applications that require the higher overload profile defined for the drive family.

• The integrated Class A filter differentiates the AL0 article from the otherwise similar UL0 unfiltered power module.
• An integrated braking chopper provides the switching function for a correctly engineered external braking resistor.
• The FSF cooling system requires 0.153 m³/s airflow and must remain unobstructed in the control cabinet.
• Long documented motor-cable limits support installations where the motor is remote from the drive cabinet.
• The 2 kHz rated pulse frequency establishes the basis for the published current and thermal data.

• Large pumps, fans and process auxiliaries using the 75 kW low-overload profile.
• Conveying, mixing and material-handling duties matched to the 55 kW high-overload rating.
• Industrial cabinets that require the integrated Class A filter of the AL0 variant.
• Modular G120 systems where the power stage, Control Unit and operator interface are selected separately.

• Use 6SL3210-1PE31-5AL0 as the complete procurement identifier; changing AL0 to UL0 removes the integrated filter and changes weight and losses.
• Check the installed duty class rather than selecting only by motor nameplate kilowatts.
• Confirm cabinet airflow, motor-cable length, braking energy and Control Unit compatibility before an exchange.
• Preserve commissioning parameters and verify the motor data after installation.
