6SL3210-1PE31-5UL0 is the unfiltered FSF version of the SINAMICS G120 PM240-2 power module. It is intended for installations where filtering and EMC compliance are managed at the cabinet or machine level.

The power stage supplies up to 145 A rated output in low-overload duty and 110 A in high-overload duty. An integrated braking chopper is available for connection to a suitable external braking resistor.

• The UL0 suffix identifies an unfiltered power module and should be retained exactly in procurement and maintenance records.
• Published low- and high-overload current values provide separate sizing points for variable-torque and heavier cyclic duties.
• The internal air-cooling path is sized for the FSF power stage and depends on correct cabinet clearances.
• A braking chopper is incorporated, while the resistor and its thermal protection remain external engineering items.
• Vector and V/f output-frequency ranges support a broad selection of industrial motor-control tasks.

• Drive cabinets using centralized line filtering or another documented EMC solution.
• 75 kW low-overload fan and pump duties in modular SINAMICS G120 architectures.
• 55 kW high-overload material-handling and process-machine applications.
• Retrofit projects that must match an existing FSF unfiltered PM240-2 footprint and cooling plan.

• Identify the spare as 6SL3210-1PE31-5UL0 rather than substituting the heavier filtered AL0 variant without engineering review.
• Compare line supply, motor current, overload cycle, pulse frequency and external filter arrangement.
• Inspect fans, airflow path and cabinet heat removal as part of scheduled drive maintenance.
• Back up parameters and document the Control Unit, option modules and braking resistor before replacement.
