Core Functions

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

Standard SERCOS bus realizes high-speed data transmission and precise multi-axis synchronization.

Integrated cooling structure adapts to compact cabinet layout and saves installation space.

Modular design enables flexible function expansion and easy field maintenance.

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

Supports torque, speed and position control modes to satisfy diverse medium-power motion requirements.

Application Scenarios

Medium-sized CNC machine tools and processing equipment

Medium-load multi-axis synchronous production lines and handling robots

Printing, textile, packaging and general industrial automation machinery

Precision test benches and motion simulation devices

Digital renovation projects for medium-power automation equipment

Usage and Maintenance

Install the drive vertically and ensure sufficient 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 reliable operation.
