DR1-08ACY25 AC servo driver

What’s the difference between a servo controller and a servo driver

First, servo driver is also known as “servo controller”, “servo amplifier”, is used to control the servo motor of a controller, its role is similar to the frequency converter acting on the ordinary AC motor, belongs to a part of the servo system, mainly used in high precision positioning system. Generally, the servo motor is controlled by position, speed and torque to achieve high precision positioning of the transmission system.

2. At present, the mainstream servo drivers all adopt 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, at the same time with over voltage, over current, overheating, undervoltage and other fault detection protection circuit, in the main circuit also added to the soft start circuit to reduce the impact of the start process to 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.
