Drive ratings and overload capability
The Siemens 6SL3511-1PE21-5AM0 is a SINAMICS G110D AC drive rated for 1.5 kW under high overload duty on a 380-500 V three-phase supply. The overload profile is what governs real-world motor sizing: 200% for 3 seconds, 150% for 60 seconds, and 100% for 300 seconds — meaning it can handle a 3-second starting surge at double rated current without tripping, provided the thermal load cycle respects the recovery period. That profile suits applications like conveyors or small pumps where the motor sees intermittent peak loads, not continuous full-torque stall.
Enclosure and deployment context
That makes it suitable for washdown environments or outdoor installation without a separate cabinet — a common requirement on food-and-bev lines or in material handling zones where hose-down cleaning is routine. The FSA frame size measures 210 x 450 x 145 mm (HxWxD); plan the gland plate and cable-entry clearance accordingly, especially if routing motor and supply cables through the same gland plate.
Integrated filter, braking chopper, and bus interface
This variant includes an integrated Class A EMC filter, so it meets conducted-emission limits for industrial environments without an external filter module — saves panel space and one wiring step. The integrated braking chopper allows dynamic braking with an external resistor, which is useful for loads that regenerate during deceleration (vertical conveyors, centrifuges). The AS-Interface bus interface is the drive's fieldbus connection; it communicates directly on an AS-i network without an external gateway, simplifying wiring for distributed drive architectures.
