Description

Designed for highly precise industrial motion control, the ASD-A1021-AB serves as a reliable AC servo drive within the ASDA-A series architecture. This drive delivers precise speed, torque, and position control for dynamic automation environments. It integrates seamlessly with high-performance AC servo motors, providing closed-loop feedback systems with high-resolution encoder compatibility to maintain position accuracy under varying load conditions.

The unit features multiple control modes, including external pulse train input, internal parameter command, and analog voltage control. Dual communication interfaces support standard Modbus protocols, facilitating direct integration with PLCs, HMIs, and host controllers in complex automation layouts.

Features

  • Dual control modes for versatile position, speed, and torque regulation.
  • Built-in dynamic brake for rapid deceleration and safety shutdown sequences.
  • Integrated RS-232 and RS-485 communication interfaces for remote configuration and diagnostic monitoring.
  • SVPWM (Space Vector Pulse Width Modulation) control algorithm for optimized motor efficiency and reduced thermal dissipation.
  • Robust low-pass and P-curve smoothing filters to suppress mechanical resonance and vibration during high-speed transitions.

Applications

  • CNC machine tools and precision milling machinery.
  • High-speed packaging and filling equipment.
  • Textile processing and winding machinery.
  • Automated material handling systems and pick-and-place robotics.
