How to Wire and Control an AC Servo with Arduino: Step-by-Step Guide

[@peterk3068]

Wonderful job. Please share the code and the wiring diagram if possible.

Working with steppers, I've found that it may not be good idea to have abrupt changes in speed/direction. I would include some ramp-up/ramp-down functions for servos too. I'm planning one project to have 2..3+kW servo for moving something with 50-80kg weight at considerable speeds. Quite a lot of inertia there, it sure won't go or stop on a dime.

[@tarehjernetarehjerne4082]

@@SeersantLoom you can do that. Just create a method for ramping in the code.

Great job, man!

Thnx man, it's very helpfull :)

Hi , can you give us the Arduino code for test? Thank you ❤

[@BertrandBru]

Thanks for this tutorial. It was really useful. I bought the same servo motor and driver and in 15min, I was able to control it. Have you ever tried to control this servo motor by position? E.g. go to 20 degrees or go back to intial position. I guess you would need to get position feedback from the encoder. Do you thik this would be possible with an arduino? Thanks in advance.

Hello, You can indeed recieve position output through the arduino. The demonstration was done in a step/dir open loop connection. Note the arduino program needs a lot of checks to run a good closed loop system that would not self interfere. I have created closed loop systems with these servos but i have only done so using a PLC. If you wish to create your own system, i would do it with ladder logic and a PLC, micro chips are not fast enough if you wish to go faster.

Hello, In the video, the program 48 of the servo driver is set at 1000. When set with the tone function tone(pin13, 10*1000, 1000), the servo motor do complete turn in one second. Does it means that if the program 48 was set at 500, the servo motor would turn twice in one second? Thank you.

Good job please can i have the code and diagram?

"Exactly what I was looking for! Thank you. I ordered a Lichuan servo a few months ago, thinking it would be as straightforward as any other stepper motor with step and direction pins connected to an Arduino. Could you please assist me in figuring out how to make it move? Is it possible to get your email? It would be very helpful."

[@tarehjernetarehjerne4082]

I can try to assist, but i need to know what model you have. Have you tried what i did in the video? This should be universal for the lichuan servos

[@KlemenVidmar]

this will probably sound stupid but why does the motor constantly spin if you wired it to position mode? Shouldnt that be speed mode?

[@tarehjernetarehjerne4082]

That is not a stupid question. Here, we are sending a tone which changes the position, making it look like its spinning. In an industry setting you would send 5000 pulses in 0.1s to rotate 180 degrees. In speed mode, i believe it works off an analog voltage as a motor.

Hi,my name is Million Haile.can you show me a programm and wiring of arduino to servo to control for bar soap cutting machine with adding induction prox.sensor and encoder?Regards Million Haile

[@tarehjernetarehjerne4082]

I can try to be of help. For a machine purpose I would not use an arduino. Please check out the Mesa store for linux cnc parts.

it's very useful.
