Material Composition
Industrial-grade components with advanced circuit design. Compact housing with robust construction for harsh industrial environments.

Structural Features
Compact footprint ranging from 28.7mm to 94.6mm in width, enabling installation in tight spaces. Multiple connector options for power, feedback, and communication.

Working Principle
The drive converts AC or DC input power into precisely controlled three-phase AC output for brushless servo motors. The full-digital control architecture executes current, speed, and position closed-loop algorithms with 800Hz speed loop bandwidth, enabling rapid response to command changes while maintaining smooth motion.

Installation Requirements

  • Install in a control cabinet with adequate ventilation.
  • Ensure proper grounding and cable shielding.
  • Use locking connectors for all power and feedback connections.
  • Verify input voltage matches the drive specification.

Usage Notes

  • The 800Hz speed loop bandwidth eliminates the need for servo loop tuning in most applications when paired with AKM servo motors.
  • Select appropriate feedback interface option card based on the motor encoder type.
  • Monitor drive status through the user interface for fault diagnostics.
  • Ensure adequate cooling space around the drive.
