Working Principle
The board obtains working power from the drive power module, collects external control signals and drive operating parameters through the input interface, transmits the processed signals to the drive main control chip. At the same time, it converts the drive operating state and fault information into switch signals and outputs to external alarm and interlock equipment, realizing the man-machine and inter-equipment signal interaction of the drive.
