  • RTA - R-MOD ETNew series of stepper motors with integrated ministep bipolar chopper drives; setting by means of EtherCAT interface and based on battery less multi-turn absolute encoder.
  • Compact system housed in a metallic box mounted on motor body, minimizing dimensions and optimizing wiring and mounting easiness.
  • Target: advanced applications with distributed electronics requiring compact dimensions and ensuring perfect integration in complex EtherCAT architectures.


  • Communication by means of EtherCAT (CoE) interface.
  • Modes of operation: PROFILE POSITION and CSP.
  • Different variety of HOMING operation modes.
  • TOUCH PROBE hardware input.
  • Motor current overboost.
  • Intelligent management of the current profile.
  • Battery less multi-turn absolute encoder


  • Range of operating voltage: 24-48 VDC.
  • Protections:
    - Protection against under-voltage and over-voltage.
    - Protection against a short-circuit at motor outputs.
    - Overtemperature protection.
  • Electronic damping facility for further acoustic noise and mechanic vibrations reduction.
  • Command to execute runs with position control to set: distance, direction, speed and acceleration.
  • Command to execute zero research (HOMING).
  • Possibility to detect motor loss of synchronism or stall and position error by means of battery less multi-turn absolute encoder.
