An overcurrent fault in an inverter occurs only when you power on the inverter or during motor running. It is necessary to first check the hardware and the parameters of the inverter and the motor before resetting the error to prevent damaging or exploding the inverter and motor.
However, inverters may encounter various faults during operation. This article will introduce the common faults of inverters in detail, including electrical quantity faults, current problems, frequency and voltage problems, internal component faults, grounding faults and other problems, and provide corresponding solutions. 1.
During normal operation, we may encounter the inverter prompting the current limit. For general inverters that cannot work normally and smoothly when the current limit alarm appears, the voltage (frequency) must be lowered first until the current drops to the allowable range.
In an inverter, the codes for overcurrent faults are typically labeled as OC1 and OC2. OC1 indicates that the current is over the threshold of the inverter’s protection setting, which is the motor''s overcurrent.
Our standardized container products are engineered for reliability, safety, and easy deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
