Product Name: AD300 high performance AC drive [Download User Manual]

AD300 high performance vector control AC drives
AD300 series is a high performance series universal current vector control AC drives. Integrated with both open-loop and closed-loop(optional) vector control modes, it can drive both normal AC asynchronous induction motors and PM synchronous motors with excellent performance. It is specially designed to be robust with large capacity for heavy duty and complicated electric motor driving applications.

AD300 Software features

  • Unique intelligent current vector control
  • RENESAS 32-bits high speed CPU specialized for motor control
  • Different control modes:
      a. Sensor-less vector control(2 types: fuzzy/precise modes);

      b. Closed-loop vector control with PG (OPTIONAL feature)
      c. V/F control (3 types)
  • Speed detection restart (flying start)
  • Good linearity in torque control
  • * Adjustable from 0%~200%, avoiding runaway in torque linear increasing or declining

  • Dynamic torque current control offers fast response to the load change.
  • Current limitation function for Acc.
  • *Its special current algorithm does not influence the starting torque, avoiding faults caused by the large starting current in some applications.

  • Extraordinary torque performance in low frequency
  • *SVC mode outputs 150% torque in 0.5Hz, meeting applications which require high torque at low frequency such as CNC spindle and crane.

  • Strong overload capability (last 20 seconds for 180% current)
  • High precision synchronization control
  • Rich functions include multi-steps, PID, fixed length, wobble frequency, etc.
  • Complete protections for the drives and motors.

AD300 Structure features

  • Independent air duct separates the electrical part from the heat radiation duct to reduce the damage rate.
  • Compact design, reduce the volume and increase the power density through heating design and simulation; the product volume is generally 70% of competitors’
  • European style compact structure design based on scientific heat radiation emulation; save the end user’s panel space maximally
  • Full series drives use DC fans, avoiding the radiation failure caused by AC fans problems.
  • Drives housing: Good quality aluminum coated zinc plate and coating design provides not only reliable grounding and shielding but also anti-corrosive protection (11kW and above).
