Schneider SM100-40-080-P0-45-S1-B1 Retrofit-Ready Servo Motor for Lexium Control Systems
The Schneider Electric SM100-40-080-P0-45-S1-B1 is a high-performance AC servo motor from the Lexium series, engineered for demanding industrial motion control applications. As legacy automation lines face increasing pressure to modernize, this unit serves as a direct retrofit-ready replacement for discontinued or end-of-life servo motors in Schneider Lexium-based control architectures. Whether you are upgrading a packaging line, a CNC machining center, a textile machine, or a material handling system, the SM100-40-080-P0-45-S1-B1 delivers the torque density, encoder resolution, and communication compatibility required for a smooth, low-risk migration.
This motor is designed to integrate seamlessly with the Lexium 32 and Lexium 62 servo drive families. Engineers replacing older SM-series motors — including discontinued variants such as the SM100-40-080-P0-30 and SM100-40-080-P0-45-S1-B0 — will find that the SM100-40-080-P0-45-S1-B1 maintains backward-compatible mechanical mounting dimensions and encoder interface standards, significantly reducing retrofit engineering time and downtime risk.

Retrofit Planning for Existing Automation Systems
Replacing a servo motor in a live production environment requires careful pre-migration planning. When integrating the SM100-40-080-P0-45-S1-B1 into an existing Lexium-based control cabinet, engineers should begin by auditing the current Lexium 32A or LXM32M servo drive to confirm firmware compatibility with the SM100-P0-45 motor parameter set. In many retrofit scenarios, the drive’s motor table must be updated via EcoStruxure Machine Expert (formerly SoMachine Motion) before the new motor is energized.
Power supply capacity is a critical checkpoint. The existing 24 VDC control power supply and the DC bus supply feeding the Lexium drive must be verified against the SM100-40-080-P0-45-S1-B1’s rated current draw and peak torque demand. In multi-axis cabinets where several LXM32 drives share a common Lexium power supply module or regenerative braking resistor, the total bus load must be recalculated after substitution.
Terminal wiring is another area requiring close attention. The motor power connector (U, V, W, PE) and the feedback cable connector must be matched to the existing cable harness. If the original installation used a VW3M5101 or VW3M5102 motor cable, verify pin-out compatibility with the B1 shaft variant. The brake wiring (24 VDC, typically routed through the TM5 I/O module or a dedicated relay output on the Modicon M241 or M262 logic controller) must also be confirmed before powering up.
For systems using CANopen DS402 motion profiles, the node address and baud rate settings stored in the Lexium drive’s non-volatile memory are preserved during motor swap — no re-parameterization of the network layer is required. However, if the system communicates over Modbus TCP via an LMC058 motion controller or a Modicon M340 PLC, engineers should verify that the axis object mapping in the application program correctly references the new motor’s rated parameters.
Backplane and rack considerations apply when the servo system is integrated with a Modicon X80 I/O rack or a BMX CPS power supply module. Ensure that the rack’s available current budget accommodates any additional I/O expansion modules added during the upgrade. If the retrofit also involves adding encoder feedback redundancy or a safety STO module, the rack slot allocation must be reviewed in the hardware configuration within EcoStruxure.
Downtime Control During System Migration
Minimizing production downtime during a servo motor replacement is achievable with disciplined pre-staging. Before the maintenance window opens, the SM100-40-080-P0-45-S1-B1 should be bench-tested against a spare LXM32A drive using the commissioning wizard in EcoStruxure Machine Expert. This confirms that the motor parameter file loads correctly, the encoder signal is clean, and the STO function responds as expected — all before the unit reaches the production floor.
The original application program — including motion sequences, cam profiles, and axis homing routines — should be backed up from the Modicon M262 or LMC058 controller to a secure project archive prior to any hardware change. If the HMI (such as a Magelis HMIGTO or Vijeo Designer-based panel) displays axis status or position feedback, verify that the screen variables remain correctly mapped after the motor swap. In most cases, no HMI modification is required since the axis object references remain unchanged at the controller level.
During the physical swap, label and photograph all existing cable connections before disconnection. Restore power in stages: control power first, then bus power, then enable the drive. Run the auto-tuning sequence to update the current loop and speed loop gains for the new motor’s inertia profile. Validate positioning accuracy against the original teach points before returning the machine to automatic mode. A structured commissioning checklist — covering encoder signal verification, brake release test, jog movement, and full-cycle production test — ensures that the retrofit is completed within a single planned maintenance shift.
Retrofit Support FAQ
Q1: Is the SM100-40-080-P0-45-S1-B1 a direct drop-in replacement for the SM100-40-080-P0-45-S1-B0?
Yes. The B1 suffix denotes the shaft configuration (smooth shaft with keyway), while the B0 suffix indicates a plain smooth shaft. Mechanically, the flange dimensions, encoder connector, and power connector are identical. Confirm your coupling or pulley bore matches the B1 shaft diameter before installation.
Q2: Does this motor require drive firmware updates when paired with an existing Lexium 32 drive?
In most cases, Lexium 32 drives running firmware v2.0 or later already include the SM100-P0-45 motor parameter table. If your drive is running an earlier firmware version, download the latest release from Schneider Electric’s support portal and update via EcoStruxure Machine Expert before commissioning the new motor.
Q3: What pre-shipment testing is performed on this unit?
Each SM100-40-080-P0-45-S1-B1 unit undergoes outgoing quality inspection including insulation resistance testing, encoder signal verification, and mechanical rotation check. A test report is available upon request. All units are covered by a 12-month warranty from the date of shipment, covering manufacturing defects and encoder failure under normal operating conditions.
Q4: Can this motor be used in a multi-axis system with mixed Lexium drive generations?
Yes, provided each axis uses a compatible Lexium drive variant (LXM32A, LXM32M, or Lexium 62). The SM100-40-080-P0-45-S1-B1 is not cross-compatible with non-Lexium drive platforms without re-parameterization. For mixed-generation cabinets, verify that the shared DC bus voltage and regenerative energy capacity are within specification for all axes combined.
