10kV bus voltage too high incoming line trips
Monitor AC line for high line voltage or transient conditions phase-phase and phase-ground. Use RSLogix trend or Drive Observer - monitor DC bus, speed, and current. The DC bus overvoltage fault, also called a DC bus error or simply an overvoltage fault, is among the most common faults on an AC variable frequency drive. Because it's so common, some newer drives try to assist with locating the issue by providing more information about what the drive was doing. Whether you're facing an overcurrent trip, overvoltage fault, or mysterious communication error, understanding the root cause and having a systematic approach makes the difference between a 10-minute fix and hours of costly downtime that can range from $1,000 to $10,000 per hour depending on your. Cause : Overvoltage comes when voltage in the DC bus has exceeded the overvoltage detection level. If the drive is on an ungrounded. Regenerative drives are built to handle excess energy, but when voltage levels spike beyond safe limits, your drive trips to protect itself. Maybe it only happens during high deceleration? Or maybe it's completely random? Either way, production stops, and downtime starts adding up fast.
