Product Overview

The Schneider LXM23AU10M3X Lexium 23 Motion Servo Drive is a 1 kW AC servo drive in the Lexium 23 Plus series. It operates from a single-phase 200–255 V AC supply or a compatible three-phase supply within its specified voltage range. The drive regulates a connected servo motor and supports position, speed and torque control for industrial machine axes.

This model is suited to applications requiring repeatable positioning, controlled acceleration and coordinated movement between machine mechanisms. Packaging equipment, automated assembly systems, material-handling machinery and dedicated production machines are typical applications where servo control helps maintain consistent motion throughout a production cycle.

The LXM23AU10M3X supports CANopen communication and programmable pulse-based positioning configurations. It also provides programmable digital inputs and outputs, analog command inputs and an encoder feedback interface. These features allow the drive to operate within different machine-control architectures, depending on the controller and selected operating mode.

When integrating this drive into an existing machine, engineers should verify the motor’s rated current and power, encoder compatibility, supply arrangement and communication configuration. The 1 kW rating alone does not establish compatibility with every servo motor in the same product family.

Working Principle

The LXM23AU10M3X converts incoming AC power into regulated electrical output for a compatible servo motor. It processes the selected motion command, monitors motor encoder feedback and adjusts the motor current to achieve the requested movement.

In position-control mode, the drive follows a configured position command supplied through a supported pulse interface or motion-control arrangement. In speed-control mode, it regulates the motor toward the commanded rotational speed. Torque-control operation regulates the motor’s torque-producing current according to the selected command and operating limits.

The encoder feedback allows the drive to evaluate the motor’s actual response rather than relying solely on the requested command. This feedback is important when the machine must move through repeatable distances or maintain a controlled speed under changing mechanical loads.

Consider a packaging machine that uses a servo motor to advance a film or product feed mechanism. The machine controller requests a defined movement, and the LXM23AU10M3X regulates the motor to follow that command. The controller can then coordinate the feed axis with sealing, cutting or labeling operations to maintain the required production sequence.

During deceleration, the motor may return energy to the drive. If the application produces sufficient regenerated energy, a correctly selected braking resistor may be required. Its resistance, power rating and installation must follow the drive’s electrical requirements.

The final motion response depends on the connected motor, encoder feedback, drive parameters, mechanical transmission and control architecture. Incorrect configuration can result in positioning errors, unstable movement or drive faults.

Role in a Lexium 23 Servo Control System

The LXM23AU10M3X acts as the motor power and regulation stage between the machine controller and the servo motor. It receives motion commands, processes encoder feedback and adjusts motor output to execute the required axis movement.

Industrial Applications

Installation and Maintenance

1. Verify the drive reference: Confirm that LXM23AU10M3X matches the required 1 kW rating, supply configuration and communication requirements.
2. Check motor compatibility: Compare the motor’s rated power, voltage, current and encoder specifications with the drive’s requirements.
3. Isolate the electrical supply: Follow the equipment’s lockout procedure and allow the specified DC-bus discharge time before handling power connections.
4. Prepare the cabinet: Mount the drive vertically and provide the required ventilation clearances for heat dissipation.
5. Confirm the supply circuit: Check the incoming voltage, supply phase arrangement, grounding and protective devices.
6. Connect the motor: Use a compatible power cable and verify the motor connections and protective earth.
7. Inspect the encoder wiring: Confirm the feedback cable, connector pinout and encoder compatibility before enabling the drive.
8. Configure the command interface: Select the intended CANopen, pulse-based or other supported control arrangement and configure the corresponding parameters.
9. Set the motor parameters: Enter the correct motor data and review applicable speed, torque, acceleration and deceleration limits.
10. Check braking requirements: Determine whether the application requires an external braking resistor and verify its electrical ratings before installation.
11. Perform a controlled commissioning test: Check rotation direction, feedback response, communication and motion behavior at reduced operating demand before production use.
12. Record maintenance findings: Document the drive reference, motor configuration, parameter settings, active alarms and commissioning results.

Technical FAQs

How should the LXM23AU10M3X be matched to a servo motor?

Check the motor’s rated power, voltage, current and encoder interface against the drive specifications. The machine’s load inertia, required acceleration and duty cycle should also be considered when sizing the complete motion axis.

Can the drive use a three-phase power supply?

Yes. The specified input range supports single-phase 200–255 V AC and three-phase 170–255 V AC operation. The actual supply arrangement must comply with the drive’s wiring instructions and the installation’s electrical requirements.

What is the purpose of the drive’s analog inputs?

The two voltage analog inputs accept references within the specified -10 to +10 V range. Their use depends on the selected operating mode, terminal configuration and drive parameters.

What should be checked if the motor stops with a drive fault during deceleration?

Review the active fault indication, deceleration settings, mechanical load and regenerated-energy conditions. If the application requires an external braking resistor, verify its wiring and electrical ratings against the drive specifications before returning the machine to operation.
