- Compact Footprint: 60 mm width allows dense multi-axis panel layouts — critical in space-constrained OEM machine cabinets.
- Auto-Tuning: One-button inertia identification and gain auto-tuning via SoMove software reduces commissioning time from hours to minutes.
- Wide Supply Tolerance: ±10% voltage tolerance handles unstable grid conditions common in emerging-market factory environments.
System Architecture & Signal Flow
In a typical Lexium 05 motion cell, the LXM05BD34N4 receives position/velocity setpoints from a Modicon M340 or M580 PLC via CANopen DS402 or CANmotion. The drive closes the current loop at 16 kHz PWM switching frequency, feeding a BSH or BMH servo motor. Encoder feedback (incremental or SinCos) returns to the drive’s feedback port; the drive’s position counter is then reported back to the PLC for supervisory monitoring. The STO input is wired to the machine’s safety PLC (e.g., Preventa XPSMC) to achieve category 3 / PLd stop-on-demand without cutting main power.

Technical FAQ
Q: Is LXM05BD34N4 compatible with third-party servo motors?
A: Yes, with manual motor parameter configuration via SoMove software. However, Schneider BSH/BMH motors are recommended for full auto-tuning and safety function support.
Q: What communication protocol does this drive support?
A: CANopen DS402 and Schneider’s proprietary CANmotion protocol. Modbus RTU is available via optional VW3A3607 module.
Q: Can this drive operate on single-phase supply?
A: No. LXM05BD34N4 requires 3-phase 380–480 V AC input. For single-phase applications, refer to the LXM05A range.
Q: What is the STO wiring requirement?
A: STO inputs (STO_A and STO_B) must be driven by a 24 V DC safety-rated source. Refer to Schneider application note AN-LXM05-STO for wiring diagrams.
Q: How do I commission this drive?
A: Use Schneider SoMove software (free download) via USB-RJ45 cable VW3A8106. The drive supports one-button auto-tuning after motor selection from the built-in database.
Q: What is the difference between LXM05BD34N4 and LXM05AD34N4?
A: The “B” variant includes an integrated braking resistor connection and enhanced EMC filter. The “A” variant is the base model without these features.
