Multi-axis motion controller steadily improves motion control capabilities
Release Date : 2020-07-03 16:36:10


A recent study shows that by 2025, the global multi-axis motion controller market will grow at a compound annual growth rate (CAGR) of 11%. The increasing demand for precise control systems is considered to be one of the main reasons for this expected growth.
But what does a multi-axis motion controller actually do? Why is it important in the motion control industry?
 
What is a multi-axis motion controller?
The essence of the multi-axis motion controller is to control the movement of the automation system on multiple axes. They play an important role in implementing intelligent, discrete multi-axis drive designs.
For a long time, motion control design has been very simple. There is one motor per axis, each motor has a drive, and they are connected by cables. More axes means more complex design and excessive heat.
Then, the emergence of communication protocols such as CANopen bus and EtherCAT bus enabled smarter motor drives. The combination of these intelligent motor drives and multi-axis motion controllers makes distributed architecture systems simpler and more efficient.
 
How does a multi-axis motion controller work?
Multi-axis controllers are an important part of advanced motion control systems. In this type of system, the controller sends the multiplexed signal to the motor's driver, which decodes it into individual signals. This type of synchronization is based on its own processor, and precision control can reach the nanometer level.
 
Multi-axis motion controllers play an important role in steadily improving motion control capabilities. Their expected growth in the next few years depends directly on the value and research level of their realization.
