Closed-loop PMSM / AC Servo motor drives ASD-PC Series

3-phase/380-440Vac;575-690 Vac;1000-1140 Vac;1.5KW~500KW


Typical applications: Closed loop control of various permanent magnet synchronus motors / AC servo motors supporting a wide range of feedback devices


Key features:


  • Utilizing magnetic field oriented control (FOC), with higher efficiency, more stable control function, high dynamic response and high precision control.
  • The optional active front-end module can feed energy back to the power side to maintain DC bus voltage stability when the grid-side voltage fluctuates.
  • Intelligent auto tuning.
  • Supporting the commands of pulse input, analog input and digital input.
  • Optional braking unit, external braking resistor.
  • Supporting incremental encoder, resolver, sine and cosine encoder, Hiperface encoder.
  • Supporting dual PG full closed loop control.
  • Supporting electronic gear ratio switching function.
  • Optional external accessory for electronic cam control.
  • Multi segment position control.
  • Safety shutdown function.
  • The incremental encoder resolution can reach to 1280000 p/rev.
  • Built-in PID.
  • Standard MODBUS communication.
  • Various control modes of torque, speed and position, and can be quickly switched through control terminals or communication.
  • High torque control accuracy, and can provide closed loop torque control.
  • High torque: Under the mode of FOC + PG mode, the output torque at 0Hz can be up to 300% according to customer's requirement.
