SINAMICS G120P drive, FSB frame, 5.5 kW
The Siemens 6SL3200-6AE21-3BH0 is a SINAMICS G120P variable speed drive in the FSB frame size, delivering 5.5 kW output power at 400 V operating voltage with a rated output current of 13.2 A. This puts it in the compact end of the G120P family — sized for a standard 5.5 kW 4-pole induction motor on a pump or fan duty, where the integrated Filter B (EN 61800-3 compliant) handles conducted emissions without an external line reactor for most installations.
Overload capacity and output frequency
The drive delivers 110 % overload for 57 seconds and 150 % for 3 seconds, repeating every 300 seconds — a profile that matches the load cycle of centrifugal pumps and fans where short-duration torque demand spikes occur during startup or surge events. The 550 Hz maximum output frequency extends beyond standard 50/60 Hz motor operation, so this drive can also run high-speed spindles or test stands that need 4-pole motors at several times base speed.
Communications and I/O complement
Onboard communication includes Modbus/RTU, RS485/USS, and BACnet MS/TP, with PROFIBUS, PROFINET, and CANopen available as optional add-on modules — so the drive fits into a BAS (BACnet) plant network or an industrial Ethernet architecture without a gateway. The 6 digital inputs, 4 analog inputs, and 2 analog outputs cover most standalone control and feedback loops; for a pump skid, for example, you can bring in a pressure transmitter on one analog input and a flow signal on another while commanding speed via the fieldbus.
