Product Overview
The Schneider LXM23AU15M3X Lexium 23 Motion Servo Drive is a 1.5 kW AC servo drive from the Lexium 23 Plus series. It regulates the operation of a compatible servo motor and supports position, speed and torque control for industrial machinery. The drive accepts single-phase or three-phase AC input within its specified voltage ranges and includes a CANopen communication interface for integration with compatible motion-control systems.
This model is suitable for machine axes that require controlled acceleration, repeatable positioning and coordinated movement. Applications include packaging equipment, automated assembly machinery, material-handling systems and production machines in which motor movement must follow defined operating sequences.
The LXM23AU15M3X includes programmable digital inputs and outputs, analog voltage inputs and a motor encoder feedback interface. These connections allow the drive to work with a PLC, motion controller and associated machine-control devices. The choice between network-based and pulse-based control depends on the controller architecture and the configured drive operating mode.
When selecting this drive for an existing installation, engineers should check the complete order number, motor electrical ratings, feedback interface, supply arrangement and control requirements. The 1.5 kW rating is an important sizing parameter, but the motor and drive must also be matched for current, operating conditions and the machine’s dynamic load.

Working Principle
The LXM23AU15M3X converts incoming AC electrical power into controlled output power for a compatible servo motor. It processes the selected motion command, evaluates the motor feedback and adjusts its output to achieve the requested movement.
In position-control mode, the drive follows a configured position command through a supported control interface. Speed control regulates the motor toward the requested rotational speed, while torque control regulates the motor’s torque-producing current according to the configured command and operating limits. The selected mode determines how the controller communicates the motion demand and how the drive responds.
Encoder feedback allows the drive to compare the motor’s actual response with the commanded movement. This is particularly useful in machinery where positioning errors can affect product spacing, assembly accuracy or synchronization with other axes.
Consider an automated packaging machine that uses a servo motor to advance a product feed mechanism. The machine controller issues a movement command, and the LXM23AU15M3X regulates the motor to follow the required motion profile. The controller then coordinates the feed movement with sealing, cutting or labeling operations.
During deceleration, a servo motor can return energy to the drive. If the amount of regenerated energy exceeds what the system can accommodate, an external braking resistor may be required. Its selection and installation must comply with the drive’s electrical specifications and the machine’s duty cycle.
Correct operation depends on the motor configuration, feedback wiring, command scaling and control parameters. A mismatch in these areas can cause positioning errors, unstable movement or drive faults.
Role in a Lexium 23 Servo Control System
The LXM23AU15M3X acts as the motor power-conversion and regulation stage between the machine controller and the servo motor. It receives motion commands, processes feedback and adjusts the motor output to execute the required axis movement.

Technical FAQs
How does the LXM23AU15M3X differ from the 1 kW LXM23AU10M3X?
The LXM23AU15M3X has a nominal power rating of 1.5 kW, compared with 1 kW for the LXM23AU10M3X. Selection should also account for continuous output current, motor ratings and the machine’s acceleration and load requirements.
Can this drive be connected to either a single-phase or three-phase supply?
Yes. Its specified input range is 200–255 V AC for single-phase operation and 170–255 V AC for three-phase operation. The actual connection must follow the drive’s wiring requirements and the installation’s electrical design.
What should be checked when configuring CANopen communication?
Verify the network wiring, node configuration, communication settings and controller support. The drive’s communication parameters must match the CANopen master configuration before the machine is commissioned.
How can regenerated energy affect the drive during repeated deceleration?
Repeated deceleration can return energy from the motor to the drive. If the application exceeds the system’s energy-handling capability, a suitable braking resistor may be necessary. Check the deceleration profile and resistor requirements against the drive specifications.
