Core Functions

  • Current/speed/position three‑loop control for stable dynamic performance

  • BE12 fiber‑optic SERCOS for high‑speed, precise multi‑axis synchronization

  • External cooling reduces cabinet heat load, enabling smaller enclosures

  • Detachable FW module allows quick replacement and data recovery

  • Modular design supports flexible expansion and easy maintenance

  • Comprehensive protection: overvoltage, undervoltage, overcurrent, short circuit, overheating, feedback loss

  • Torque/speed/position control modes for medium‑power motion applications

Application Scenarios

  • Medium‑duty CNC machine tools and precision machining centers

  • Multi‑axis automated lines and medium‑load handling robots

  • Textile, printing, and packaging machinery

  • Automation systems using BE12 SERCOS fiber‑optic communication

  • Medium‑power servo system assembly and equipment retrofitting

Usage and Maintenance

  • Install vertically and ensure unobstructed external cooling airflow

  • Operate below 45 °C to avoid performance derating

  • Install FW module correctly, complete wiring, then commission via IndraWorks

  • Clean heat sink and air passages every 6 months; inspect terminals periodically

  • Calibrate control loops every 2 years to maintain stability

  • Transfer FW module to new unit for rapid system recovery during replacement
