To fix overvoltage, extend the deceleration ramp time constant from 5 seconds to 10 or 15 seconds, or install a properly sized dynamic braking resistor.
: Overvoltage is typically triggered by aggressive deceleration ramps where the motor acts as a generator, pumping energy back into the drive's DC bus. Undervoltage is caused by line sags, loose incoming supply lines, or sub-par smart grid integration. The Fix : To fix overvoltage, extend the deceleration ramp time
Ensure the VFD, motor frame, and enclosure share a single, low-resistance ground point to eliminate electrical noise that disrupts integrated PLC signals. Systematic Troubleshooting Flowchart The Fix : Ensure the VFD, motor frame,
