ovn
ovn on DELTA inverters: Over-voltage at constant speed
DELTA inverters: MS300
Disconnect the supply and wait for the capacitors to discharge before opening the inverter or touching its terminals.
Common causes
- The load drives the motor faster than set (overhauling)
- Sudden rise in supply voltage
Try first
- Measure the supply voltage
- Add a braking resistor for overhauling loads
