Product Introduction & Supply Chain Strategy
The ELAU SM-100-40-080-P0-45-M1-B1 is a robust 100mm frame servo motor engineered for high-demand industrial applications within the PacDrive M ecosystem. Utilizing a multi-turn SinCos Hiperface encoder, it provides absolute position feedback, making it ideal for complex multi-axis machines in food processing and pharmaceuticals where precision and power density are non-negotiable.
Strategically, this specific model is a vital “insurance” component for aging plants. As manufacturers transition to newer platforms, securing “New Surplus” units of the SM-100 series is the only way to avoid the risks associated with refurbished hardware—such as degraded encoder precision or winding fatigue. Maintaining a 1-unit safety stock on-site drastically reduces Lead Time Variability and secures your plant against the high Total Cost of Ownership (TCO) caused by emergency EOL (End of Life) sourcing during a breakdown.
Installation & Configuration Guide
Stage 1: Pre-Installation (Prep & Safety)
Execute standard Lock-Out/Tag-Out (LOTO) procedures. Use a grounded ESD wrist strap before handling the encoder connections. Compare the serial number and firmware suffix (V010001) with the existing unit to ensure total hardware parity.
Stage 2: Removal
Disconnect the power and feedback circular connectors. Loosen the mounting bolts. If the motor is coupled to a drive train, use a puller if necessary, but avoid any axial or radial shock to the shaft, which can damage the internal high-resolution encoder.
Stage 3: Installation (Clone & Seat)
Verify the mounting surface is clean. Replicate any specific mounting orientations. Slide the motor onto the mounting flange and tighten bolts. The “P0” designation indicates a smooth shaft; ensure your coupling is torqued to prevent slippage. Reconnect cables, ensuring the locking rings are hand-tight to maintain the IP65 rating.
Stage 4: Power-On & Testing
Upon powering the MC-4 or PacDrive controller, the motor’s electronic nameplate will be read automatically. Check for any “Absolute Position” faults. Perform a homing routine to calibrate the multi-turn feedback before resuming high-speed operations.

Firmware/Software Versions & Upgrade Notes
- Electronic Nameplate: This motor features an internal data memory that stores motor parameters and commutation offsets. No manual entry of motor data is required in EPAS-4.
- Compatibility: The multi-turn encoder (“M1” suffix) is compatible with all ELAU PacDrive controllers that support the Hiperface protocol.
- Replacement Note: If replacing a single-turn motor (S1) with this multi-turn (M1) unit, you must update the PLC configuration to recognize the absolute multi-turn functionality, or positioning errors may occur after a power cycle.
Frequently Asked Questions (FAQ)
What does “New Surplus” mean for this ELAU motor?
It means the motor is brand new and has never been used in production. It typically comes from excess inventory or cancelled projects. It offers the reliability of a factory-new unit but is available for immediate shipment, which is critical for discontinued ELAU lines.
Is this a multi-turn or single-turn encoder?
The “M1” in the model code confirms this unit has a Multi-turn SinCos Hiperface encoder. It tracks the absolute position over 4,096 revolutions, meaning the machine does not need to be homed after every power-down.
Can I use this motor to replace a model with a keyed shaft?
The “P0” in this model number indicates a smooth shaft. If your current motor has a keyway, you will need to replace the coupling or choose the corresponding keyed version to ensure proper torque transmission.
Does this motor include the integrated brake?
Yes. The “B1” suffix confirms an integrated 24V electromagnetic holding brake is included, designed to hold the load in place during E-stop or power-loss conditions.
How do I know this isn’t a refurbished unit?
We provide a clear “New Surplus” guarantee. You can inspect the motor for original OEM paint, zero wear on the mounting holes, and factory-clean connector pins. Unlike refurbished motors, our units have never undergone soldered repairs or bearing replacements.
