Servo how does it work

Furthermore, with a battery voltage between 24 Vdc and 72 Vdc, NERVO guarantees an excellent balance of power, performance, and functionality. Thanks to its compactness and sturdiness, the ESA servo drive can be installed reducing costs to a minimum and integrates very well even in very confined spaces, without this compromising its output performance.

The servo drive amplifies the low power signal to make the servo motor move. Kollmorgen introduces the next generation of motion for more ambitious machines built on more capable performance and more confident engineering. The result is significantly enhanced torque, responsiveness and SafeMotion capabilities in a compact footprint that enables easy installation and total flexibility.

With significant torque increases in the same motor size OEMs can achieve substantial performance improvement without changing the motor mounting or using more machine space.

Here we just need to include the library, define the servo object, and using the attach function define the pin to which the servo is connected as well as define the minimum and maximum values of the pulses durations.

Then using the write function we simply set the position of the servo from 0 to degrees. With this library we can drive up to 12 servos at the same time or 48 servos using Arduino Mega board. It has a built in clock so it can drive 16 servos free running, or independently of Arduino.

So theoretically we can control up to servos using only the two I2C pins from the Arduino board. The 6 address select pins are used for setting different I2C addressed for each additional driver. We just need to connect the solder pads according to this table. For controlling this servo driver we will use the PCA library which can be downloaded from GitHub. So first we need to include the libraries and define the PCA object.

So the minimum pulse duration of 0. But as explained earlier these values should be adjusted according your servo motor. In my case values from to corresponded to 0 to degrees position. In the setup section we need to define the I2C clock rate, set the driver address and set the frequency to 50Hz. In that way all servos will work the same and position at the exact angle. For that purpose we need to connect the drivers to each other and connect the appropriate address select solder pads.

So we should create separate PCA object for each driver, define the addresses for each driver as well as set the frequency to 50Hz. Now simply using the setChannelPWM and pwmForAngle functions we can set any servo at any driver to position any angle we want. So that would be all for this tutorial, I hope you enjoyed it and learned something new.

Feel free to ask any question in the comments section below and make sure you can my Arduino Projects Collection. I am have just started working with Arduino and servos.

Servos I went for ar exactly the same ones like yours in the video, which means that I also had to use external power source. Here is the challenge, I think I have used wrong powers source — because wires became hot. Please, would you mind sharing more information regarding power source you were using — and also how exacactly you have wired it up through the breadboard? Power source I have used V to 5V at 15A. The middle wire of the servo is 5V, the brown GND and the yellow is signal line.

Hello, I have also one query. I was using a 6V Initially I was driving it with power source from arduino. Later I connected it with DC power supply at 7 V and I also set the current limit to max mA to be at safer side but still my servo motor got destroyed. I wanted to know what was the reason and how can I correct it. Thanks Reply. Glad you found it useful, thanks! This is a excellent website , i can find many usful article Reply.
