Drive selection memo
The Siemens 6SL3210-1KE22-6UP0 is a SINAMICS G120C compact drive rated for 11.0 kW on a 380-480 V three-phase supply, with a 150% overload capability for 3 seconds — enough to handle short-duration peak loads like a crusher start or a conveyor breakaway without oversizing the frame. PROFIBUS DP is integrated on the board. Safe Torque-Off (STO) is also built in. The I/O complement — 6 digital inputs, 2 digital outputs, 1 analog input, 1 analog output — covers most standalone pump or fan control loops without an add-on I/O module.
