Material Composition
Industrial-grade IGBT power modules, high-performance DSP controller, and robust housing suitable for panel mounting in control cabinets.

Structural Features
Compact single-axis design with dimensions of 140mm × 65mm × 35mm. Standardized connectors for power, motor, feedback, and control signals. Compatible with Servostar CD series ecosystem.

Working Principle
The drive converts 115/230V AC input through a rectifier to DC bus voltage, then uses PWM inverter to output three-phase AC to the servo motor. The FOC (field-oriented control) algorithm executes current loop control with <50μs response, while speed and position loops provide precise motion regulation through PID algorithms. The drive continuously compares feedback signals with command signals to form closed-loop adjustment.

Installation Requirements

  • Install in a control cabinet with adequate ventilation
  • Connect 115/230V AC power supply (single or three-phase)
  • Provide 24V DC logic power supply
  • Connect motor, feedback device, and control signals according to the wiring diagram
  • Ensure proper grounding

Usage Notes

  • This product has been discontinued; consider upgrading to AKD series (e.g., AKD-B00606) for new installations
  • Verify power supply voltage matches the drive specification before powering on
  • Configure control mode and feedback type through the setup software
  • Monitor drive temperature during continuous operation
  • Operating temperature range is -20°C to +60°C
