Schneider BMH1403P11A2A Upgrade Solution for Lexium BMH

Product Overview

Schneider BMH1403P11A2A Upgrade Solution for Lexium BMH

Upgrading or replacing a legacy servo motor in a Schneider Electric motion control system demands more than a simple part swap — it requires verified compatibility across wiring, drive communication, mechanical mounting, and control architecture. The Schneider Electric BMH1403P11A2A is a Lexium BMH series AC servo motor rated at 1.1 kW continuous output power, 3000 RPM nominal speed, and IP65 ingress protection, making it a proven drop-in replacement or direct upgrade for aging BMH-series motors in demanding industrial motion applications.

Whether your facility is migrating from an earlier Lexium 05 or Lexium 15 servo drive platform, or replacing a worn BMH1401 or BMH1402 frame motor that has reached end of service life, the BMH1403P11A2A maintains full backward compatibility with the Lexium 32 and Lexium 62 servo drive families. The motor’s resolver or encoder feedback interface aligns directly with the existing Lexium drive’s feedback channel, eliminating the need for signal converter modules or custom wiring adapters during the retrofit.

Seamless Upgrade Solutions

A successful migration to the BMH1403P11A2A typically involves coordinating several system components within the same control cabinet or motion axis. When paired with a Lexium 32A servo drive (e.g., LXM32AD18N4), the motor’s power and feedback cables connect directly without modification, preserving the existing cable routing and conduit layout. For installations still running a Lexium 05 drive, a drive-side upgrade to the Lexium 32 or Lexium 62 platform is recommended to unlock full parameter tuning and STO (Safe Torque Off) safety functionality.

On the control side, the BMH1403P11A2A integrates seamlessly with Modicon M340 and Modicon M580 PLC platforms via CANopen or EtherNet/IP motion bus, depending on the Lexium drive variant selected. Existing BMXDDI3202K digital input modules and BMXDDO3202K digital output modules in the M340 rack continue to handle auxiliary I/O — limit switches, home sensors, and drive enable signals — without rewiring. The BMXP342020 CPU module retains full program compatibility when the axis object parameters are updated to reflect the new motor’s rated torque and inertia values.

For installations using a Magelis HMIGTO series HMI connected to the Modicon PLC, no HMI screen modifications are required for the motor swap itself; only the drive parameter set needs updating via SoMove commissioning software or the Lexium drive’s front panel. Where the control cabinet includes a Phaseo ABL8 power supply module feeding 24 VDC logic circuits, the existing power budget remains unaffected by the motor replacement. If the application involves a multi-axis gantry or conveyor, the TeSys D contactor and associated motor protection relay in the main power circuit should be verified against the BMH1403P11A2A’s rated current draw to confirm thermal trip settings remain appropriate.

For facilities requiring signal isolation between the servo feedback loop and a legacy DCS analog input card, a Schneider BMXAMI0410 analog input module or equivalent signal conditioner can bridge the torque reference output from the Lexium drive to the plant-level control system without ground loop interference.

Retrofit Guidance FAQ

Q1: Can the BMH1403P11A2A replace my existing BMH1401 or BMH1402 motor without rewiring?
Yes. The BMH series uses a standardized IEC 90 flange and identical power/feedback connector pinout across the 1401–1403 frame sizes. The motor cable and feedback cable from your existing installation connect directly to the BMH1403P11A2A. Only the drive’s motor parameter set (rated current, pole pairs, encoder resolution) needs to be updated in SoMove or via the Lexium drive keypad.

Q2: Is this motor compatible with my Lexium 32 or Lexium 62 drive?
Yes. The BMH1403P11A2A is fully compatible with the Lexium 32 (LXM32A/D/M variants) and Lexium 62 drive families. It is also compatible with the Lexium 28 compact drive. For Lexium 05 or Lexium 15 legacy drives, a drive upgrade is recommended to maintain STO safety compliance and full diagnostic capability.

Q3: What communication protocols does this motor support in a Modicon PLC environment?
The BMH1403P11A2A itself is a passive motor; protocol support is determined by the paired Lexium servo drive. Lexium 32 drives support CANopen, EtherNet/IP, PROFIBUS DP, and Modbus TCP depending on the communication card fitted. All protocols are fully compatible with Modicon M340, M580, and Premium PLC platforms.

Q4: What physical space does the BMH1403P11A2A require compared to my legacy motor?
The BMH1403P11A2A shares the same IEC 90 frame and flange dimensions as other BMH 140-frame motors. Overall body length may vary slightly depending on brake/no-brake suffix. Verify the shaft extension length and keyway dimensions against your coupling or gearbox specification before installation. TOPNLMS can provide the full dimensional drawing upon request.

Warranty Assurance

Every BMH1403P11A2A unit shipped by TOPNLMS is covered by a 12-month warranty from the date of delivery. Prior to dispatch, each unit undergoes a multi-point inspection covering insulation resistance, winding continuity, encoder/resolver signal integrity, shaft runout, and connector seating. Units are packed in anti-static foam with moisture-barrier film to prevent transit damage.

In the event of a confirmed defect within the warranty period, TOPNLMS provides priority replacement dispatch, typically within 3–5 business days of fault confirmation. Our technical team is available to assist with installation verification, parameter configuration guidance, and compatibility confirmation before and after shipment. For urgent production-line replacements, expedited shipping options are available upon request.

Stock is maintained in Xiamen, China, with export documentation (commercial invoice, packing list, and certificate of origin) prepared for international customs clearance. Lead times for in-stock units are typically 3–7 business days to major industrial regions globally.
