Vfd Overvoltage Fault

My VFD (Siemens MM430) generates a fault at startup (F002 - Overvoltage). Whenever ON command being issued , VFD is tripping on " Over Voltage" Customer has replace the VFD with spare VFD but same issue. the cause of the issue simply disconnect the motor from the VFD output. There are two main reasons for overvoltage: Power over-voltage and over-voltage regeneration. Photos 3 and 4 show what can happen. Here is the link if. Once a system has been started and operating for many weeks, the fault rarely occurs. This will aid in prevent- ing drive over-voltage faults and damage to the drive input components when line voltage deviations occur. I have a Fuji (GE) AF-300 Mini VFD. Are you getting over voltage faults from your VFD? Erratic operation? Hearing strange noises? VFD failure? Chances are you may need to change your use and maintenance routines for your VFD and probably other equipment too. High performance variable frequency drive makes a measurement of the torque through the current to control the brake, for other it's based on speed reference. Smart VFD is also designed to run 3 phase standard and high efficiency induction motors by varying the output voltage and frequency.

By controlling motor speed, changes in load demands can be adjusted for quickly and automatically to maintain optimum process conditions. Don't let this pressure make you take even longer to resolve the problem. Macromatic's three-phase monitor relay, also known as a phase failure relay, can protect against premature equipment failure by monitoring for several common fault conditions including overvoltage. A common mistake is made in operating at an overvoltage to reduce the stator current and to reduce the introduction of heat. An over voltage fault can come from either. DC Bus becomes more means DC Bus Overvoltage, ie. Variable frequency drive DC Bus overvoltage fault Put a braking resistor on variable frequency drive. Conversely, overvoltage refers to a swell in voltage levels supplied which may occur over a short or sustained period and is the reverse of an undervoltage condition.
