Core Functions

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

Standard SERCOS bus enables high-speed data transmission and accurate multi-axis synchronization.

Built-in cooling structure fits compact cabinet layout and saves installation space.

Modular design supports flexible function expansion and convenient on-site maintenance.

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

Supports torque, speed and position control modes to satisfy various medium-power motion demands.

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 transformation projects for medium-power automation systems

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.
