The ECAT-2091S is a compact EtherCAT‑slave stepper motor controller designed for industrial applications. It drives a two‑phase bipolar stepper motor with a voltage range of 5 V to 46 V DC and a peak coil current of 1.5 A (up to 2.0 A with proper cooling). The module offers high‑resolution microstepping up to 256 steps per full step, an integrated ramp generator, and optional encoder feedback for precise positioning.
Technical data include a 5 V encoder power supply (max 150 mA output), two digital inputs, one open‑collector digital output, and a 24 V DC control supply. The device measures 110 mm × 90 mm × 33 mm, operates from –25 °C to +40 °C, and communicates via two RJ‑45 EtherCAT ports supporting daisy‑chain connections up to 100 m.
