The Siemens 6SL3200-6AM21-3AH0 is a SINAMICS G120P variable speed drive rated for 5.5 kW power output and 13.2 A output current at 400 V operating voltage, 50/60 Hz.
Overload profile and duty cycle
The drive carries a 110% overload capacity for 57 seconds and 150% for 3 seconds, every 300 seconds. That 57-second window at 110% covers most conveyor start-up and pump breakaway torque profiles; the 150% / 3-second burst handles momentary load spikes without tripping. For applications needing sustained overload beyond this duty cycle — say, a centrifuge with a long ramp — the drive will need to be sized up or the acceleration time extended.
Communication and integration
Onboard communication includes Modbus/RTU, RS485/USS, and BACnet MS/TP. PROFIBUS, PROFINET, and CANopen are available as optional add-ons. For a building-services pump or fan application, the BACnet MS/TP port connects directly to a BMS without a gateway. If the line uses PROFINET for motion control, budget for the optional communication module — it is not included in the base unit.
