Overload capability and what it means for your application
The 6SL3211-1PE23-3AL0: The high-overload rating (11 kW at 200% for 3 s) is the spec that matters for starting a loaded conveyor or a pump under head pressure — you get that short burst of torque without oversizing the drive. The low-overload rating (15 kW at 150% for 3 s) suits constant-torque applications like fans or mixers where the peak demand is lower. The integrated braking chopper handles the regenerative energy from decelerating loads, so you don't need an external resistor for most stop cycles.
Integration and mounting
The module measures 411 x 200 x 171 mm (HxWxD) in FSC format with IP20 degree of protection — it's designed for enclosure mounting, not washdown environments. It requires a separate Control Unit and operating unit; the firmware compatibility starts at CU V4.6. The integrated Class A filter meets conducted emission limits for industrial environments without an external EMC filter.
