Installation Requirements
When this series of VFDs are installed, they should be placed on the ground level. Make sure to leave enough operating space on both sides of the product. Leave a certain distance from the wall behind the product to ensure the ventilation requirements of the radiator. The radiator is required to be > 0.8m from the wall and both sides of the product should be > 1.0m from the wall.
Symptom | Level | Probable Causes |
Hardware Protection | Protection | Overvoltage Over-current IGBT Error |
Overvoltage | Protection | When multiple VFDs run, they may be in a short state of power generation The deceleration time is too short Abnormal input voltage Has energy feedback load Alarm limit parameters are set too low |
Over-speed | Protection | Position cannot be identified when starting Software Error |
Software Over-current | Protection | The over-current setting value is too low |
Under-voltage | Protection | Alarm limit parameters are set too high Abnormal input voltage There are other large load starts in the grid, causing the drop of input voltage |
Overtemperature Protection | Protection | Radiator is high at front and low at back, the heat pipe radiator doesn't work properly Overload running for long time Poor Ventilation The environment temperature is too high |
