All questions
  • Inverter installation precautions?
     Only trained and qualified professionals can carry out the installation, please follow the instructions in "safety precautions". During the installation process, you must ensure that the converter's power supply has been disconnected. If the inverter have electricity, so after a POWER outage, and short waiting time is not on the inverter marked time, and make sure the POWER light is extinguished, it is recommended that the user uses multimeter to ensure the DC bus voltage is below 36V 
  • What is the output frequency range of INVT inverter?
     Frequency setting range of inverter can reach 0-400Hz. For applications with high output frequency requirements, we can supply CHV150 products with an output frequency of up to 3000HZ. 
  • What are the inverter installation and usage environmental requirements?
    Running environment temperature is between - 10℃ ~ + 40℃, derate by 3% for each additional 1℃, the max operation temp should not exceed 50℃. Relative humidity of air is < 90% without condensation. When the installation site of the inverter is below 1000m, it can be operated at its rated power. When the elevation exceeds 1000m, it will be used at a proportional decrease of 1% of the 100m. The maximum amplitude is no more than 5.8m/S2 (0.6 g) and the inverter should be away from the source of electromagnetic radiation. The installation site should be free from oil mist, corrosive flammable gas, no radioactive material, metal dust, dust, oil, water and other foreign objects.

    Standard GD300\800\CHV190\CHV100\GD35\GD300EPS
  • Which INVT inverters support DP communications?
    GD35 GD300 GD300 GD800 IPE200 CHA100\CHV100A\CHV190
  • When large motors move together, why does the inverter stop?
    When the motor starts, it will flow through the starting current corresponding to capacity, the transformer on motor stator side will generate voltage drop, the impact of voltage reduction is large when motor capacity is large. The inverter connected to the same transformer will report undervoltage or transient stop and cause protection function to act, thus operation is stopped.
  • How does the inverter prevent thunder?
    Lightning strike is divided into direct lightning and inductive ray. Direct thunderbolt is the lightning bolt that falls directly on the lightning, causing the maximum damage; Inductive thunder is an electromagnetic wave generated by lightning that produces high voltage on the conductor, causing the electrical overvoltage on the conductor to be damaged. On the grid, a multistage arrester has been installed, but the lightning induction voltage near the residual voltage of the front lightning or the converter is still causing damage to the frequency converter. 
    Answer: Install an inlet arrester in the converter control cabinet. 
    The power lightning arrester can be used for lightning protection module, slide installation and parallel grounding. The arrester module is the gap discharge, the impact discharge current 15kA(10/350 mu s) and the working voltage of 250V. It can also be used to prevent lightning by using parallel voltage sensitive resistance on power line. 

  • What happens to the input overvoltage?
    The input of the overvoltage will cause tripping, or even damage inverter internal circuit.
  • Can ac servo motors be controlled by inverter?
    Yes, but not the accuracy of the servo controller.
  • Can the inverter of INVT be connected to the power supply of 60HZ?
    Yes, the input frequency range of the INVT inverter is 47-63Hz.
  • Can inverter single-phase 220V output three-phase 380V?
    Single-phase 220V inverter can only be output in the 3-phase 0~ 220V, and the inverter itself is not to be promoted.
