Is the PM240 FSA still the right 1.1 kW module for a 400 V cabinet?
The Siemens 6SL3224-0BE21-1UA0 is a SINAMICS PM240 power module in frame size FSA, rated 1.1 kW high overload (200 % for 3 s, 150 % for 57 s, 100 % for 240 s) on a 380-480 V 3 AC supply with an integrated braking chopper and unfiltered output — shipped as a spare module without a Control Unit or BOP. It is specified for the standard PM240 high-overload duty profile, which means the 3.10 A continuous current and 6.20 A peak (max output current) are credible for short-term transient load — conveyors, mixers, small hoists, and pump stations where the duty cycle calls for punch rather than steady-state torque.
What does the input envelope demand from the feeder?
The module takes 3 AC at 380-480 V ±10 %, 47-63 Hz, and the line-side draw is 3.20 A with a line reactor or 3.90 A without — meaning a reactor at the feeder drops input current by roughly 0.70 A and reduces the harmonic content the drive reflects back into the bus.
What does the output stage deliver to the motor?
Output is 3 AC at 3.10 A continuous in both LO and HO duty, peaking at 6.20 A, with vector control up to 200 Hz and V/f control up to 550 Hz — the 4 kHz default pulse frequency is the silent setting for most installations; raising it quiets motor whine but compounds switching losses and the FSA thermal budget.
Thermal envelope and panel placement
The FSA module is cooled by internal air and rated for 0-50 °C operation in HO duty, 0-40 °C in LO duty, with storage and transport from -25 to 55 °C; installation altitude is rated to 1,000 m above sea level and 95 % RH non-condensing is the upper humidity bound.
