ETHERCAT STEPPING DRIVES - COMBO UNIT: HI-MOD ETS AND R-MOD ET

R.T.A. srl

Stepper motor with integrated ministep bipolar chopper drive; setting by means of EtherCAT interface and based on encoder, incremental encoder or 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.

UL/CSA certified.

The Combo Unit is available in two models:

  • HI-MOD ETS with Safety SIL3
  • R-MOD ET

HIGHLIGHTS

  • STO[SIL3] function
  • Error Detection Monitor
  • Communication by means of EtherCAT (CoE) interface. 
  • Modes of operation: PROFILE POSITION and CSP. 
  • Different variety of HOMING operation modes. 
  • PROXIMITY hardware input. 
  • Motor current overboost. 
  • Intelligent management of the current profile.

TECHNICAL SPECIFICATIONS

  • Range of operating voltage: 32-75 VDC, 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 encoder, Incremental Encoder or Multi-Turn Absolute Encoder.
