frequency inverter breakdown(2)

Overcurrent fault

Overcurrent fault can be divided into acceleration, deceleration, constant speed over current. It may be due to the inverter acceleration and deceleration time is too short, the load changes suddenly, the load distribution is uneven, the output short circuit and other causes. At this time, generally, the acceleration and deceleration time can be prolonged to reduce the sudden change of load, and the energy consumption braking element can be used to carry out the load distribution design and check the line. If you disconnect the load inverter or over-current fault, inverter inverter circuit is ring, you need to replace the inverter.
