Core Functions

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

DS45 SERCOS interface provides ultra-fast data transmission and strong anti-interference capability, ideal for complex multi-axis linkage systems.

Compact internal cooling structure fits installation in cabinets with limited space.

Modular design enables flexible function expansion and simple on-site maintenance.

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

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

Application Scenarios

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

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

Metal forging, stamping and other heavy processing equipment

Industrial automation systems demanding top-level bus communication stability

High-power servo system assembly and technical renovation projects

Usage and Maintenance

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

Keep ambient temperature below 45 °C during operation.

Install the matching firmware module and complete all wiring work before commissioning. Configure operating parameters via IndraWorks software.

Clean internal fan and heat sink every 6 months, and inspect terminal connections regularly. Calibrate control loops every 2 years to maintain long-term operational stability.
