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

  1. The load drives the motor faster than set (overhauling)
  2. Sudden rise in supply voltage

Try first

  1. Measure the supply voltage
  2. Add a braking resistor for overhauling loads
