Overload fault including the frequency overload and motor overload, may be the acceleration time is too short, the DC braking is too large, the grid voltage is too low, overloading and other causes. Generally by extending the acceleration time, to extend the starting time, check the grid voltage is resolved. Overload usually see, in fact, should first analyze in the end is the motor is overloaded or the inverter itself overloaded. In general, the motor overload due to strong motor parameters as long as the drive parameter table set properly, generally do not overload the General Assembly. The drive itself is poor due to overload, it is prone to overload alarm. We can detect a fault inverter output voltage, current detection circuit and so easy to point to one troubleshooting. Overload of the main reasons (1) the main features of mechanical overload is a motor heat, operating current can be read from the display to find. (2) three-phase voltage imbalance caused by a running current phase is too large, leading to overload trip, which is characterized by uneven heating of the motor, running current read from the display may not be able to find (due to display only one phase current). Inside the inverter current sensing section (3) failure of malfunction, the detected current signal is too large, leading to tripping.
