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. .
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. Comparing Overvoltage trip thresholds with the nominal DC bus voltage we can see that the overvoltage trip settings for most drives is 130-150% of nominal DC bus voltage. Corresponding AC voltage at which overvoltage fault occurs can be calculated by dividing the above values by 1.35. [pdf]
