Schneider LXM62DD27D21000 Lexium 62 Servo Drive

The Schneider LXM62DD27D21000 is a multi-axis servo drive module from the Lexium 62 range. Designed for distributed motion control, this drive module is powered from a common DC bus and provides a rated output current of 27 A. It is compatible with Lexium 62 power supplies and can be used with BMH or BSH servo motors. The drive supports CANopen and EtherCAT communication protocols for integration into motion networks. It is suitable for packaging, printing, material handling, and other high-speed positioning applications.

Technical Specifications

Rated output current: 27 A (continuous). Peak current: 54 A (for 2 seconds). Supply voltage: 300-600 V DC (from Lexium 62 DC bus). Output power (nominal): 7 kW (depending on motor). Control interfaces: CANopen (DS402) and EtherCAT (CoE) with integrated switch. The drive includes 2 digital inputs (24 V DC), 1 digital output, and 2 analog inputs (±10 V) for external sensors. Built-in safety: STO (Safe Torque Off) SIL3/PL e. Dimensions: 70 mm (W) × 300 mm (H) × 240 mm (D). Protection rating: IP20. Operating temperature: 0°C to 50°C. Storage: -25°C to 70°C. The drive is cooled by forced air (integrated fan).

Key Features

• Common DC bus operation (shared power supply with multiple drives)

• Dual communication ports: CANopen and EtherCAT (with integrated switch)

• Supports position, speed, and torque control modes

• STO (Safe Torque Off) safety function (SIL3/PL e)

• Integrated motor holding brake control

• Auto-tuning and adaptive filtering for motor optimisation

• Electronic motor nameplate for quick setup

• Removable screw terminal blocks for I/O and motor power

Integration with Lexium 62 System

The LXM62DD27D21000 is part of the Lexium 62 modular drive system. It must be connected to a Lexium 62 power supply module (e.g., LXM62P10xxxx) that provides the DC bus voltage. Multiple drive modules can be mounted side-by-side on a common busbar, sharing the DC bus and communication bus. The system supports up to 16 axes per power supply. Configuration is performed using Schneider’s SoMove software or via the fieldbus (CANopen/EtherCAT) with device profile DS402. The drive also includes a web server for diagnostics.

Communication and Control

The drive supports CANopen DS402 (CiA 402) and EtherCAT (CoE). In EtherCAT mode, cycle times as low as 1 ms can be achieved. The integrated two-port Ethernet switch allows daisy-chaining of drives without external switches. The drive supports cyclic synchronous position (CSP), velocity (CSV), and torque (CST) modes. It also implements homing and interpolated position modes. The CANopen interface supports SDO and PDO with up to 5 PDOs per node.

Installation and Wiring

Mount the drive vertically on a DIN rail (35 mm) or directly to a backplane. Connect the DC bus (from power supply) to the busbar connectors on the rear. Connect the servo motor power (U, V, W) and brake (if equipped) to the screw terminals. Connect the encoder feedback (Hiperface, EnDat, or resolver) via the D-sub connector. For STO, connect the two safety inputs (24 V DC) in series with the emergency stop circuit. For I/O, wire sensors/actuators to the 14-pin I/O connector. Use shielded cables for encoder and fieldbus connections. Provide adequate clearance for the fan intake and exhaust.

Applications

Typical applications include high-speed pick-and-place machines, rotary table indexing, flying shear cut-offs, slitter-rewinders, and robotic axis control. The drive’s 27 A rating is suitable for motors up to 7 kW, covering a wide range of industrial automation needs.

Environmental and Compliance

The LXM62DD27D21000 is CE, UL, and RoHS certified. It meets EN 61800-3 (EMC) and EN 61800-5-1 (safety). Operating temperature: 0-50°C, derate above 40°C. Humidity 10-95% non-condensing. Vibration 2g (10-55 Hz). The unit must be installed in a pollution degree 2 environment.

Conclusion

The Schneider LXM62DD27D21000 Lexium 62 servo drive delivers precise motion control for multi-axis systems. Its 27 A rating, common DC bus architecture, and dual-fieldbus support make it a flexible and powerful choice for demanding automation applications.
