DNV510 series frequency inverter/frequency converter/AC drive is the high-end inverter of HNC. It concludes below improvement & invovation based on the ordinary V/F inverter. With the high-end design and high quality and reliability, DNV510 series inverter will bring the users all new experience.    150% of starting torque at 0.5HZ, 180% of the zero speed torque at 0HZ(sensorless vector control)
5. Superior responsiveness
  Sensorless vector control, the torque corresponding <20ms, sensor vector control, the torque response <5ms
6. Motor overheating protection
Selection of input and output expansion card, analog input AI3 can accpet motor temperature sensor input (PT100, PT1000,) when the motor temperature exceeds the alarm value, the inverter output pulse signal, suggesting overheating, when the motor temperature exceeds the overtemperature protection, inverter failure output gives motor properly protected
7. Prompt current limit function
Prompt current limit feature allows the inverter to avoid frequent overcurrent alarm, when the current exceeds the current protection, current is promptly limited under the protection point, to protect the safety of the equipment to avoid interference due to suddenly applied load or caused by the over-current alarm.
8. Multi-motor switch
Have the set of motor parameters, to achieve the four-motor switch, the switching of the synchronous motor and induction motor.
9.Inverter non-stop while Instantaneous electricity failure
Inverter will not stop while Instantaneous power failure or voltage is suddenly reduced, the inverter reduces the output speed by load feedback energy, lower offset voltage, in order to maintain the inverter continues to run within a short time.
10. Virtual IO functionality
Can set 5 groups of virtual DIDO, virtual DI terminal state can be directly given by the function code, or bind to the corresponding virtual DO function.
11. Flexibility use of analog input and output
   A. Each analog inputs (AI1 to AI3), users can set the four points of the curve, use more flexiblely
   B, AI1 ~ AI3 factory calibration or user-site calibration zero drift or gain calibration accuracy of 20MV
  C. A0 can be factory calibration or user site calibration zero drift or gain calibration accuracy up to 20MV
  D .AI1 ~ AI3 can be used as a DI
  E AI3 isolated inputs can be used as PT100, PT1000, or plus or minus 10V output
12.Rich scalability
User programmable control card
Powerful back-end software functionality
Ease of use
Restore the user parameters
13 Support a variety of fieldbu.s
RS485
PROFIBUS-DP
CANLINK
CANOPEN
14. 7.5KW more than standard DC reactor is built-in for inverters over 7.5KW
