The Siemens 6AG1210-1PE31-2AL0 is a SINAMICS G120 variable frequency drive in the FSF frame size, rated for 75 kW output power and delivering 220 A continuous current with 0.98 efficiency. The IP20 enclosure means it is panel-mount only—sized for controlling three-phase induction motors in pumps, fans, conveyors, and general duty applications.
Panel fit and cooling
At 708 mm high × 305 mm wide × 357 mm deep, the drive needs a generous backpanel opening, and internal air cooling demands 0.153 m³/s of airflow—plan for clearance around the heat sink. No condensation allowed, so locate away from washdown areas.
Built-in protection and braking
Comprehensive motor and system protection is integrated: stall, overload, ground-fault, short-circuit, overvoltage, and undervoltage. This single drive replaces the need for separate motor protection relays in most installations. The brake design includes DC and compound braking, with provision for an external resistor; the integrated brake chopper is standard for sizes up to FSGX.
