Product Overview

Schneider SM100-40-080-P0-45-S1-B1 Replacement Lexium Servo: Seamless Transition from Legacy Motion Systems

Upgrading or replacing a failed Schneider Electric SM100-40-080-P0-45-S1-B1 Lexium AC servo motor does not have to mean extended downtime or costly re-engineering. This SM100 series motor is a direct-fit replacement solution designed to integrate into existing Lexium motion control architectures with minimal modification to wiring, programming, or mechanical mounting. Whether your facility is migrating away from an end-of-life servo drive system, recovering from an unexpected motor failure, or executing a planned modernization of a legacy motion axis, the SM100-40-080-P0-45-S1-B1 provides a validated, specification-matched upgrade path.

The SM100 series belongs to Schneider Electric’s Lexium platform, which spans servo drives, servo motors, and associated motion controllers. The SM100-40-080-P0-45-S1-B1 designation encodes key performance parameters: a 400 W continuous power rating, 0.80 Nm nominal torque, P0 shaft configuration (plain shaft without key), 45 mm flange, single-turn absolute encoder (S1), and B1 connector orientation. These parameters are critical when cross-referencing against the original motor nameplate during a like-for-like replacement or when evaluating compatibility with an existing Lexium 05 or Lexium 15 servo drive.

In retrofit scenarios where the original drive is a Lexium 05A or an older VSD08 variant, the SM100-40-080-P0-45-S1-B1 maintains full electrical compatibility through the standard Lexium motor feedback cable and power cable pinout. The encoder interface uses the standard Hiperface protocol supported across the Lexium drive family, meaning no encoder adapter or signal converter is required. Customers migrating from a BSH0552P or BSH0701P Lexium BSH series motor to the SM100 platform should verify the flange size and shaft diameter against their existing coupling and gearbox before installation.

For facilities running Modicon M340, Modicon M580, or Modicon Premium PLCs as the motion controller, the SM100-40-080-P0-45-S1-B1 integrates through the Lexium drive’s CANopen or Modbus RTU interface without requiring changes to the PLC program structure. Motion function blocks written for the Lexium platform remain valid, and axis parameters such as velocity limits, torque limits, and homing sequences can be retained from the original commissioning file. This significantly reduces re-commissioning time during a replacement event.

When the replacement involves a full drive-and-motor swap — for example, replacing a legacy Lexium 05 drive alongside the SM100 motor — the associated VW3M3102 motor power cable and VW3M3302 encoder cable should be inspected and replaced as part of the same maintenance window. Reusing aged cables with a new motor introduces risk of intermittent faults that are difficult to diagnose in the field. Similarly, if the motor is mounted to a gearbox or ballscrew assembly, the coupling insert and shaft key (if applicable) should be checked for wear before the new motor is installed.

Control cabinet integration is straightforward. The SM100-40-080-P0-45-S1-B1 is designed for 230 V AC single-phase or three-phase supply through the Lexium drive, so no changes to the cabinet power distribution or circuit breaker sizing are required for a like-for-like replacement. The motor’s IP65 protection rating and operating temperature range are consistent with the original SM100 specification, making it suitable for the same environmental conditions without additional enclosure modifications.

For multi-axis systems where the SM100-40-080-P0-45-S1-B1 operates alongside other Lexium axes — such as a Lexium 32A drive controlling a larger BSH1001P motor on the same machine — the replacement of a single axis does not affect the CANopen network topology or the master controller’s node addressing. The replacement motor can be commissioned on the same node ID as the original without reconfiguring the network.

Procurement teams should note that the SM100-40-080-P0-45-S1-B1 is stocked and available for immediate dispatch from our Xiamen warehouse. Each unit undergoes pre-shipment functional verification including insulation resistance testing, encoder signal validation, and shaft runout measurement. Orders are typically processed within one business day, with DHL Express and FedEx International Priority available for urgent replacement requirements.

Seamless Upgrade Solutions

A successful SM100-40-080-P0-45-S1-B1 replacement typically involves coordinating several related components within the same Lexium motion system. The Lexium 05A servo drive is the most common paired drive for this motor class and should be inspected for firmware version compatibility before commissioning the replacement motor. If the drive itself is also end-of-life, a simultaneous upgrade to a Lexium 32A drive provides a forward-compatible platform with enhanced diagnostic capabilities and STO (Safe Torque Off) safety function support.

The VW3M3102 motor power cable and VW3M3302 encoder feedback cable are the two interface cables that connect the SM100 motor to the Lexium drive. These should be replaced alongside the motor in any unplanned failure scenario to eliminate cable-related fault recurrence. For cabinet installations where cable routing space is constrained, the B1 (axial) connector orientation of this unit simplifies cable management compared to radial connector variants.

In systems where the Lexium drive communicates with a Modicon M340 CPU via a BMXNOC0401 CANopen network module, no changes to the network configuration or EDS file are required when replacing the SM100 motor. The drive retains its CANopen node address and PDO mapping, and the M340 program continues to execute motion commands without modification. For facilities also running Modicon TM5 distributed I/O on the same control network, the replacement event does not affect I/O polling or network cycle time.

If the retrofit scope extends to the HMI layer, a Magelis HMIGTO series touch panel connected to the Lexium drive via Modbus RTU can display motor status, fault codes, and axis position data without requiring screen reconfiguration, provided the drive’s Modbus register map has not changed between firmware versions.

Retrofit Guidance FAQ

Q: Can I reuse my existing motor power and encoder cables?
A: Yes, if the cables are in good condition and the connector type matches the B1 (axial) orientation of this unit. Inspect for insulation damage, connector pin corrosion, and shield continuity before reuse. Replace cables that show any signs of degradation.

Q: Do I need to re-tune the servo drive after replacing the motor?
A: For a like-for-like SM100-40-080-P0-45-S1-B1 replacement, the existing drive parameter file can be restored from backup. If no backup exists, the Lexium drive’s auto-tuning function can re-establish the current loop and velocity loop gains in a controlled test run. Full re-commissioning is recommended if the motor is being installed on a different mechanical load.

Q: Is the CANopen node address retained after motor replacement?
A: The CANopen node address is stored in the Lexium drive, not the motor. Replacing the motor does not change the drive’s node address or network configuration. The PLC program and HMI configuration remain valid.

Q: What if my existing drive is a Lexium 05A and I want to upgrade to Lexium 32A?
A: The SM100-40-080-P0-45-S1-B1 is compatible with both drive generations. Upgrading the drive requires remapping the motor parameters in the new drive’s commissioning software (SoMove) and verifying the power cable pinout, as connector types differ between drive generations. Contact our technical team for a migration checklist.

Q: What is the physical installation space requirement?
A: The SM100 series uses a 45 mm flange (NEMA 23 equivalent). Verify that the existing motor mounting plate and coupling accommodate this flange size. The motor body length for the 400 W variant is approximately 100 mm excluding shaft extension.
