DG820 High Performance AC Drives (V/F control, SVC1, SVC2, VC control)

  • DG820 VFDs support auto-tune of two motors.
  • DG820 AC drives can output up to 180% of the Rated torque at 0.5Hz under V/f mode and SVC1 mode, output up to 180% at 0.25Hz, SVC2 mode, while at VC mode up to 200% at 0Hz.
  • Speed control and torque control can be switched via terminal or programmed by parameter.
  • DG820 drives are configured with electronic gear, quite convenient for the applications when the encoder is not easily to be mounted at the motor shaft. The shaft that the encoder is mounted at is requested to have fixed spinning speed ratio with motor shaft.
