Lexium 05 servo drive — 3 kW, 380-480 V, obsolete
The Schneider Electric LXM05BD34N4 is a Lexium 05 series motion servo drive rated at 3 kW nominal power at a 4 kHz switching frequency, accepting three-phase 380...480 V supply with a -15...10 % tolerance window that extends to 323...528 V limits. Continuous output current is 11 A at 8 kHz or 15 A at 4 kHz, with a transient overload capability of 18 A at 8 kHz for 3 seconds and 24 A at 4 kHz for 3 seconds — the carrier frequency trade-off directly impacts the thermal headroom available for high-torque moves. Line current draw is 7.7 A at 480 V and 9.7 A at 380 V, with a 60 A inrush on power-up that the upstream protection must accommodate without nuisance tripping.
Obsolete — sourcing through surplus channels
Available through independent surplus and broker channels; quantities are lot-specific and confirmed at RFQ. No pin-compatible drop-in replacement exists from the original manufacturer — a board-level redesign would be required for a functional alternative.
Inputs, safety integration, and EMC
The drive carries 2 safety discrete inputs and 4 logic discrete inputs, enabling direct connection to safety-rated circuits without an external safety relay for basic stop functions. An integrated EMC filter is built into the unit, reducing the need for external line filtering in most industrial panels — the leakage current is specified at 30 mA maximum. Supply frequency tolerance is 47.5...63 Hz with a 5 % stability requirement, and the maximum prospective line short-circuit current is 5 kA — coordinate the upstream MCCB or fuse accordingly.
