Panasonic servo drive is a controller used to control Panasonic servo motors, and its function is similar to that of a frequency converter acting on an ordinary AC motor. Currently, the mainstream Panasonic servo drivers all use digital signal processors ( DSPs) as the control core, which can realize relatively complex control algorithms, digitize, network and intelligent things. Power devices generally adopt driving circuits designed with Intelligent Power Module (IPM) as the core. IPM integrates driving circuits and also have fault detection protection circuits such as overvoltage, overcurrent, overheating, and undervoltage. Soft start circuits are also added to the main circuit to reduce the impact of the startup process on the driver. The power driving unit first rectifies the input three-phase power or mains power through a three-phase full-bridge rectifier circuit to obtain the corresponding DC power. The three-phase permanent magnet synchronous AC servo motor is driven by a three-phase sinusoidal PWM voltage inverter. The entire process of the power driving unit can be simply said to be the AC-DC-AC process. The main topological circuit of the rectifier unit (AC-DC) is a three-phase full-bridge uncontrolled rectifier circuit.
