What is a servo drive?
When the servo drive in use malfunctions, if the operator does not understand the structure and configuration of the servo drive,
it will cause greater damage to the servo drive. Before conducting maintenance, it is necessary to have a preliminary understanding of our servo drive.
Servo drives, also known as “servo controllers” or “servo amplifiers”, are a type of controller used to control servo motors. Their function is similar to that of
a frequency converter acting on a regular AC motor, and they are part of a servo system, mainly used for high-precision applications. Generally, servo motors
are controlled through three methods: position, speed, and torque to achieve high-precision positioning of the transmission system. Currently, it is a high-end
product in transmission technology.
For this servo drive, Guangdong Technical Standard has focused on developing multiple maintenance plans, which can quickly detect the problem points of the
servo drive and have a high repair rate. What are the working principles of servo drives? Currently, mainstream servo drives use digital signal processors (DSPs)
as the control core, which can implement complex control algorithms, achieve digitization, networking, and intelligence. Power devices commonly use drive circuits
designed with intelligent power modules (IPMs) as the core. IPMs integrate drive circuits internally and have fault detection and protection circuits for overvoltage,
overcurrent, overheating, undervoltage, etc. Soft start circuits are also added to the main circuit to reduce the impact of the start-up process on the driver. The power drive
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. After rectification,
the three-phase power or mains power is used to drive the three-phase permanent magnet synchronous AC servo motor through a three-phase sine PWM voltage type
inverter frequency conversion. The entire process of the power drive unit can be simply described as the AC-DC-AC process. The main topology circuit of the rectifier unit
(AC-DC) is a three-phase full bridge uncontrolled rectifier circuit. With the large-scale application of servo systems, the use, debugging, and maintenance of servo drives
are important technical issues for servo drives today. More and more industrial control technology service providers have conducted in-depth technical research on servo drives.
Technical standards require targeted maintenance technical solutions for servo drive maintenance.
