SGDF-A1CS AC servo amplifier

It can realize more complex control algorithm, realize digitization, network and intelligence. Power devices generally use intelligent power module (IPM) as the core design of the drive circuit,IPM internal integrated drive circuit, and has overvoltage, overcurrent, overheating, undervoltage and other fault detection protection circuit, in the main circuit also added soft start circuit, in order to reduce the impact of the start process on the driver. The power driving unit first rectifies the input three-phase or mains power through the three-phase full-bridge rectifier circuit to obtain the corresponding direct current. The three-phase permanent magnet synchronous AC servo motor is driven by the three-phase sinusoidal PWM voltage inverter. The whole process of power drive unit can be simply described as AC-DC-AC process. The main topological circuit of AC-DC is the three – phase full – bridge uncontrolled rectifier circuit.
With the large-scale application of servo system, the use of servo drive, servo drive debugging, servo drive maintenance are more important technical topics in today’s servo drive, more and more industrial control technology service providers on the servo drive technology in-depth research.
