Servo driver principle: At present, the mainstream servo drivers all use digital signal processor (DSP) as the control core, which can realize more complex control algorithms, and realize digitalization, networking 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 add a soft start circuit to reduce the impact of the start process on the driver. The power drive unit first rectifies the input three-phase or mains 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 after the rectified three-phase power or mains. The whole process of the power drive unit can be simply said to be the AC-DC-AC process. The main topological circuit of the rectifier unit (AC-DC) is the three-phase full-bridge uncontrolled rectifier circuit.
The role of the servo driver: The servo driver is to drive the servo motor to generate power and normal operation of the equipment, its function is divided into many kinds, and with the different functionality of the brand is not the same. The servo motor functions similar to Kefeng Automation are relatively more, and there are roughly the following aspects:
1, regeneration and dynamic braking function;
2, quick stop instant power failure protection function;
3, absolute value system voltage monitoring, low voltage warning function;
4, grouping parameter setting, online switch any control mode;
5, parameter management, monitoring, oscilloscope power can support software debugging.
6, control power AC input, configurable wide voltage input;
The company focuses on DCS, PLC, robot, large servo four systems
The main products are various modules/cards, controllers, touch screens, servo drivers
