Core Functions

Three-loop control of current, speed and position ensures stable dynamic response under heavy loads.

DS03 SERCOS interface features higher transmission rate and stronger anti-interference ability for complex multi-axis linkage.

Integrated firmware simplifies on-site commissioning without additional modules.

Compact cooling structure adapts to limited cabinet installation space.

Modular design supports flexible function expansion and easy maintenance.

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

Supports torque, speed and position control modes for high-power motion control applications.

Application Scenarios

High-precision heavy-duty CNC machine tools and machining centers

Large multi-axis automated production lines and heavy-load handling robots

Metal processing, packaging and large textile machinery

Automation systems with high requirements for bus communication stability

High-power servo system assembly and equipment retrofitting projects

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.
