Can you tell that this is a robot playing the piano?
Not long ago, a piano master Lang Lang was quite confused.
That is, the robot can also play the piano. Isn't this a job hunting? In order to prove the artistry of the music, he even brought his lover to PK with the robot with "53 roots".
Finally, I had to express admiration for the speed of the robot, and even gave an evaluation: the speed of the robot is very uniform, and there is no wrong sound.
So what is it that gives robot fingers so magical? How to achieve such precise motion control? The answer is the servo drive system.
As the core unit in the field of modern motion control, the servo drive system can achieve high-precision transmission positioning. It mainly includes two parts: a servo drive and a servo motor. The servo drive receives the instructions (speed, position and torque) from the host computer, and then the host computer instructions Send it to the servo motor, so as to realize the control of the movement.
This is the working principle of the servo drive system.
Do you think that just like this, the servo control system can allow the robot to play wonderful music.
It's not that simple. The above is just the simplest operation control. If only one finger of the robot is allowed to move, there is no problem at all.
However, if you want to make the 53 fingers of the robot move at the same time, this requires a servo control system to control multiple objects at the same time, so as to achieve complex mechanical actions. In this way, the problem is coming.
For a long time, the servo drive and the servo motor are separated independently. The servo drive is placed in the control cabinet, and the servo motor is installed in the machine. The two are connected by a Cable. If it is to control a motion unit, this connection method is completely no problem.
However, if multiple motion units are controlled, such independent designs will bring a lot of inconvenience.
For example, in some longer-distance production lines, because the distance between the servo motor and the drive is restricted, the use of such a servo system often requires the use of multiple control cabinets.
So what you see is this:
Or something like this:
Seeing such a complicated electrical cabinet, everyone sees it.
With the advancement of technology and driven by user needs, a "distributed servo drive system" came into being, which easily solved all the above problems.
The Beckhoff AMP8000 distributed servo drive system is such a "magical" existence.
So, how does it do it?
First, adopt a compact integrated design
The servo drive is directly integrated into the servo motor. The size of the servo motor is only extended by 7 cm. It can be connected to the upper computer through a communication line. Therefore, the drive and the motor are integrated.
A typical distributed servo drive system becomes the following:
In this way, there is no need to install a driver in the control cabinet, just install a coupler module, which can be connected to a distributed interface module through a cable, and finally realize the purpose of connecting multiple servo motors.
Each distributed module of AMP8000 can control 5 servo drives, and each distributed module can also be cascaded in the past.
Therefore, even a complex machine or production line can be realized with a simple topology, which not only greatly reduces the space occupied by the control cabinet.
It also solves the problem that multiple control cabinets are needed on the production line due to too many servo motors or too far apart.
Secondly, adopt Beckhoff's unique EtherCAT P single cable technology
The DC power supply and the operation control bus of the motor are integrated into one cable; in the past, the signal transmission was signal transmission, and the power supply was power supply, and two cables were used for the two.
Now, with one cable, EtherCAT signal transmission and power supply can be realized at the same time, which greatly simplifies the installation process and makes the cable layout clearer, reduces wiring errors, and minimizes the space requirements of the control cabinet.
So, you see the actual application of the distributed servo system is like this:
In addition, in addition to realizing the characteristics of these distributed servos, TwinSAFE will soon be integrated into the AMP8000 system.
Seamlessly integrate safety functions into the standard control platform, such as emergency stop, safety door monitoring, two-hand operation safety mat monitoring, and mute, safe position, safe speed limit, etc., to achieve more complex safety functions.
So, if you have the following requirements in motion control:
a. Occasions with strict requirements on space
b. occasions with strict requirements for equipment safety
c. The equipment occupies a large area and the layout of the production line is complicated
Why not try Beckhoff's AMP8000 distributed servo drive system.
