Overvoltage This is caused by a high intermediate circuit DC voltage. This can arise from high inertia loads decelerating too quickly, the motor turns into a generator and increases the inverter’s DC voltage. There are other causes of DC overvoltage, however. POSSIBLE FIXES: 1. Turn the overvoltage controller is. .
This is detected by an imbalance of the currents supplying the motor implying a leakage current to earth is present. This is usually caused by poor insulation resistance to earth. POSSIBLE FIXES: 1. Check insulation resistance of the motor and cabling. 2.. .
We hope you found the information in this article useful if you have a fault not listed and you need technical assistance contact our engineering team. .
This occurs when the motor is taking too much current with reference to the value in Group 99, motor data. POSSIBLE FIXES: 1. Check that motor’s load is not excessive. 2. Check acceleration time – too fast an acceleration of a high inertia load will cause too. [pdf]
[FAQS about The inverter has voltage after power failure]
An inverter converts the DC electricity from sources such as or to AC electricity. The electricity can be at any required voltage; in particular it can operate AC equipment designed for mains operation, or rectified to produce DC at any desired voltage. An (UPS) uses batteries and an inverter to suppl. Converters and inverters are electrical devices that convert current. Converters convert the voltage of an electric device, usually alternating current (AC) to direct current (DC). On the other hand, inverters convert direct current (DC) to alternating current (AC).
