ETEL EA‑S0M‑300‑40 80A‑0000‑00 Motion Control Module

The ETEL EA‑S0M‑300‑40 80A‑0000‑00 is a high‑power motion control module designed for driving large servo motors in heavy‑duty industrial applications. This module combines a high‑performance controller with a powerful amplifier stage capable of delivering up to 80 A continuous current (and higher peak currents) from a 300 VDC bus. It is intended for use in large machine tools, extrusion presses, crane systems, and rolling mills, where high torque and robust performance are essential.

The module features advanced digital signal processing for precise current, velocity, and position control with a fast update rate of up to 32 kHz. It supports a wide range of feedback devices including resolvers, incremental encoders, absolute encoders (EnDat, BiSS, SSI), ensuring compatibility with various motor types. The integrated control algorithms include auto‑tuning, notch filters, and anti‑resonance to optimize performance under varying loads.

This model includes comprehensive I/O: 8 digital inputs (24 VDC), 4 digital outputs (24 VDC, 1 A), 2 analog inputs (±10 V), and 1 analog output. It communicates via EtherCAT, CANopen, or RS‑485, enabling integration into complex automation networks. Safety functions such as STO, SS1, and SLS (SIL 2) are built‑in, complying with machine safety standards.
