Core Functions

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

• BE33 fiber‑optic SERCOS for high‑speed, precise multi‑axis synchronization (optimized for complex motion systems)

• External cooling reduces cabinet heat load, enabling smaller enclosures

• 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 requiring high‑noise‑immunity SERCOS 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 firmware 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 firmware module to new unit for rapid system recovery during replacement
