Drive selection memo — 6SL3200-6AE15-8BH0
The Siemens 6SL3200-6AE15-8BH0 is a G120P variable speed drive in FSA frame size with an integrated Class B EMC filter, rated for 2.2 kW output power and 5.9 A output current on a 400 V supply. It delivers output frequencies up to 550 Hz, which covers standard induction motors and higher-speed spindle applications without needing an external output filter for the frequency ceiling. The overload capacity — 110% for 57 seconds and 150% for 3 seconds every 300 seconds — matches the typical pump and fan duty profile the G120P series is tuned for, meaning it handles short-duration load spikes without upsizing the frame.
I/O and fieldbus — what connects
Six digital inputs and four analog inputs give this drive enough local I/O for basic speed setpoint, start/stop, and feedback from a pressure or flow transmitter without a separate I/O module. Two analog outputs can feed a panel meter or a remote PLC with actual speed or current signal. Native Modbus/RTU, RS485/USS, and BACnet MS/TP are onboard; PROFIBUS, PROFINET, and CANopen are optional add-on modules, so the drive fits into both building-automation BACnet plants and factory-floor PROFINET lines depending on the option slot.
It carries CE, UL, RCM, and EAC product conformity marks, covering installations in North America, Europe, Australia, and the Eurasian Customs Union without separate certification work. The drive is designed to EN 61800-3, the adjustable-speed drive EMC standard, which defines both emission and immunity limits for the drive category and the filter class (Filter B here) that determines the installation environment.
