What to do if Parker Servo Drives show DB unit IGBT fault alarm?
- AAngela WilliamsJul 27, 2025
If your Parker Servo Drives show a DB unit IGBT fault alarm, check the wiring and verify the value of the brake resistor.
What to do if Parker Servo Drives show DB unit IGBT fault alarm?
If your Parker Servo Drives show a DB unit IGBT fault alarm, check the wiring and verify the value of the brake resistor.
What causes M1 phase IGBT fault alarm in Parker Servo Drives?
The M1 phase IGBT fault alarm in Parker Servo Drives is caused by excessive output current.
What to do if my Parker Servo Drives show an output overcurrent?
If your Parker Servo Drives display an output overcurrent error, it indicates the output current is exceeding the trip level. Inspect the output wiring and motor for any insulation breakdown or short circuits, both between phases and between phase and earth.
Why does my Parker Servo Drives show M1 phase IGBT over-temperature?
The M1 phase IGBT over-temperature warning on your Parker Servo Drives means the maximum IGBT junction temperature has been exceeded. Check the main cooling fan and its power supply. Ensure the cooling path isn't blocked and clean or replace the cubicle inlet air filters.
