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. 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: Turn the overvoltage controller is on. [pdf]
[FAQS about The voltage of the power frequency inverter is too high]
An inverter with adjustable voltage and frequency is commonly referred to as a Variable Frequency Drive (VFD). These devices are designed to control AC motor speed and torque by adjusting both the power frequency and voltage, allowing for precise motor control and energy savings1.Frequency inverters can generate an AC voltage that is variable in amplitude and frequency from a constant AC voltage, making them essential for applications that require controllable speed2. They convert fixed-frequency AC power into adjustable-frequency AC power, enabling efficient and flexible control of electric motors3. [pdf]
