What this PM240-2 brings to a cabinet
The Siemens 6SL3210-1PE18-0ALI is a SINAMICS Power Module PM240-2 in FSA frame size — the compact, panel-mount inverter section for a drive system. It takes 380-480 V ±10% three-phase input at 47-63 Hz and delivers 8.80 A in high-overload (HO) duty or 10.10 A in low-overload (LO) duty, depending on the load profile you need to meet. That HO/LO split matters: HO (8.8 A) gives you 150% overload for 60 seconds — good for conveyors, crushers, or any start that needs a torque punch. LO (10.1 A) is for constant-torque applications like fans or pumps where you just need the continuous current and a lighter overload curve. Pick the rating that matches your motor nameplate and duty cycle. Output frequency spans 0-550 Hz for V/f control and 0-200 Hz for vector control, with a 4 kHz pulse frequency standard. That covers most induction and synchronous motors in the power range; the 550 Hz ceiling handles high-speed spindles or test stands without an external filter.
