FX-316 Servo driver EMERSON

FX-316

The mainstream servo driver adopts digital signal processor (DSP) as the control core, which can realize more complex control algorithm, and realize digitalization, networking and intellectualization. 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.
Servo driver is an important part of modern motion control, which is widely used in industrial robots and CNC machining centers and other automation equipment. Especially, the servo driver used to control AC permanent magnet synchronous motor has become a research hotspot at home and abroad. Current, speed, position 3 closed-loop control algorithm based on vector control is widely used in AC servo driver design. Whether the speed closed-loop design in this algorithm is reasonable or not plays a key role in the whole servo control system, especially in the performance of speed control.
