The main circuit fuse fusing is a common fault of SCR servo driver. The causes of fuse fusing are as follows

The "phase sequence" of power incoming line is incorrect. Due to the synchronization problem between the trigger pulse and the main circuit of SCR servo driver, there are strict requirements on the "phase sequence" of the input power supply. If the "phase sequence" is not correct, connecting the power supply may immediately cause the fuse of the main circuit of the driver to blow.
