Core Functions

Three-loop control of current, speed and position ensures excellent dynamic response and positioning accuracy.

DS55 SERCOS interface provides higher communication speed, stronger anti-interference and better synchronization for complex multi-axis linkage.

Integrated cooling structure suits compact cabinet layout and saves installation space.

Modular design supports flexible function expansion and convenient field maintenance.

Comprehensive protection against overvoltage, undervoltage, overcurrent, short circuit, overheating and feedback signal loss.

Supports torque, speed and position control modes to meet high-standard motion control demands.

Application Scenarios

High-precision medium-sized CNC machine tools and machining centers

Complex multi-axis synchronous production lines and automated handling robots

Printing, textile and packaging machinery requiring high-speed data transmission

Precision test equipment and motion simulation devices

Digital automation projects with strict requirements on bus communication stability

Usage and Maintenance

Install the drive vertically and ensure adequate ventilation inside the cabinet.

Keep ambient temperature below 45 °C during operation.

Complete wiring of DC bus, control power, motor cable, feedback cable and SERCOS bus before commissioning. Configure parameters via IndraWorks software.

Clean internal fan and heat sink every 6 months, and inspect terminal connections periodically. Calibrate control loops every 2 years to maintain stable operation.
