Schneider Electric LXM28AU04M3X Lexium 28 400 W Servo Drive

LXM28AU04M3X a compact Lexium 28 servo drive for 400 W motors

The LXM28AU04M3X is a Schneider Electric product listed in the datasheet as: motion servo drive, Lexium 28, single and three phase, 200 to 240V, 400W. The Lexium 28 is a compact servo drive family for synchronous servo motors in general-purpose motion control, and this 400 W (0.4 kW) unit runs from a 200 to 240 V single or three-phase supply. It is applied for positioning axes, packaging and feeders where a pulse train, analogue or CANopen setpoint is used. Seven Star LLC supplies the LXM28AU04M3X in Oman and the GCC as an independent supplier based in Muscat.

Decoding the reference: LXM28 is the Lexium 28 family, A is the version whose datasheet lists pulse train, analogue and CANopen/CANmotion interfaces, U04 is the 400 W rating, and M3X marks the 200 to 240 V class. The datasheet lists a compact housing and no EMC filter.

Technical specifications of the LXM28AU04M3X

Servo capabilities of the LXM28AU04M3X

Supply voltage: 200 to 240 V (tolerance -10 % / +15 %)three phase; 200 to 240 V (tolerance -20 % / +15 %)single phase. Supply voltage limits: 200 to 255 V three phase; 170 to 255 V single phase. Network frequency: 47.5 to 63 Hz. Supply frequency: 50/60 Hz (tolerance -5 % / +5 %). Discrete inputs: 8 programmable CN1; 1 pulse train input (PTI) CN1; 2 fast capture CN1; 1 safety function STO CN9. Discrete outputs: 5 logic output CN112 to 24 V DC; 1 pulse train output (PTO) CN1. Analogue inputs: 2. Analogue input types: V_REF voltage analog input – 10 to 10 V 10 kOhm 14 bits; T_REF voltage analog input. Input voltage: 24 V DC logic. Output voltage: 12 to 24 V DC. Output voltage: <= power supply voltage.

Continuous output current is 2.6 A at 16 kHz with a 3-second peak of 7.8 A at 220 V, so the drive supports short high-torque moves. The I/O set includes eight programmable inputs, five logic outputs, a pulse train input, a pulse train output, two fast capture inputs and two analogue inputs.

Safety and network are built in: STO is integral and the safety level is quoted as SIL 2 and PL d, and the drive offers CANopen and CANmotion on RJ45 along with RS485 Modbus serial line slave. Encoder feedback is on connector CN2.

Lexium 28 in a machine design

Within the Lexium range the LXM28 sits below the LXM32 and the integrated drives. It is a good choice when the control is a PLC with pulse or analogue outputs and the machine does not need the larger safety or fieldbus features of the LXM32.

The drive must be paired with a compatible servo motor and encoder cable; check the motor reference and rated power. The 400 W unit pairs with small servo motors, so the mechanical load must also be sized for the motor torque and inertia.

Selection checklist for the LXM28AU04M3X

• Motor: matching Lexium servo motor, cable and brake if required.
• Supply: single or three phase 200 to 240 V (limits 170 to 255 V single phase).
• Command mode: pulse train, analogue, or CANopen/CANmotion.
• Safety: confirm the STO wiring and the safety relay.
• Brake resistor: check whether regeneration needs one for the axis.
• Filter: this version has no EMC filter, so ask about an external one.

Wiring and tuning of the LXM28AU04M3X

Separate power, encoder and control wiring, and use the specified encoder cable with the screen bonded at both ends. The datasheet lists spring terminals for the power connection, which saves time but requires ferrules for stranded wire.

Tune the axis using the drive’s auto-tuning with the load coupled, then confirm the following error and limit settings. Save the parameter set to a file, because a servo drive replacement without it means manual re-tuning.

Typical applications of the LXM28AU04M3X in Oman and the GCC

In Oman and the GCC small servo axes are used in packaging and labelling machines, in pick-and-place units, in dosing and filling equipment and on test benches. Clean cooling air and a dust-tight cabinet are the usual practical needs in the region.
