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.

The output power of Panasonic AC servo motor is generally 0.1-100 W, and the power frequency is divided into 50 Hz, 400 Hz, etc. It is widely used in various automatic control and recording systems 1.Miniaturization design 1) Through the best thermal analysis of the driver, the miniaturization is realized. Compared with the past, the volume is 75% and the weight is 80% 2) The new punching process of thin die steel plate has greatly reduced the iron loss, shortened the motor length (70% in the past) and reduced the number of drive models. It adopts current grading method to prepare and maintain. One driver is suitable for multiple motors and can identify automatically.
