6SL3210-1PE31-8AL0 is a frame-size FSF PM240-2 with an integrated Class A filter and braking chopper. It provides the high-power conversion stage while the paired Control Unit supplies the selected control and communication functions.

Its 178 A low-overload and 145 A high-overload rated currents define two distinct sizing points. The correct point depends on the motor load cycle rather than on nominal kilowatts alone.

• The PM240-2 converts the three-phase line supply into controlled motor power within the SINAMICS G120 modular architecture.
• Its integrated Class A filter addresses the article-level EMC configuration, while installation practices still determine overall compliance.
• The braking chopper switches energy into an external braking resistor during suitable regenerative deceleration events.
• A separately selected Control Unit defines fieldbus, safety and application-control capabilities.

• Use only with a compatible SINAMICS G120 Control Unit and supported firmware combination.
• Match the motor current and overload cycle to the 178 A LO or 145 A HO rated operating point.
• Confirm the FSF mechanical envelope, 0.153 m³/s airflow and cabinet heat-removal capacity.
• Select line-side components, motor cable, braking resistor and protection according to the complete drive-system design.

• 90 kW variable-torque pump and fan systems.
• 75 kW higher-overload conveying, extrusion or processing machinery.
• Large filtered drive cabinets requiring the FSF PM240-2 footprint.
• Modernization projects retaining a modular G120 Control Unit and operator concept.
