| Abstract: | The network motor protector based on DeviceNet achieved a set of DeviceNet communication,current monitor,motor protector overload,phase imbalance,ground fault and other fault warning and protection as a whole,according to the RMS current criteria,which is as fieldbus node using DN1022 chip.The practical results show that the network motor protection based on DeviceNet can protect motor on real-time efficiently,and can be used as nodes mounting on the DeviceNet fieldbus to communicate with the master station. |
