UniLogic servo system + external encoder


Recommended Posts

Hello everyone,

I am working on one very interesting project and I need your support. I will try to explain my project task.

It is a machine for precise metal strip cutting. This machine has two rollers. Servo motor is connected to one roller and on second roller is connected external incremental encoder. 

Incremental encoder is uses as an additional inspection, because the drive rollers where the servo is connected often slip.

I know that the servo motor has its own built-in encoder, and uses it for precise positioning.

My question is How can I use external incremental encoder for precise positioning of the servo motor?

When I used FB for MC_MoveRelative  need to set distance and my servo motor is automatically stop when reached this distance, but in this cause I need to stop motor when my external encoder reaches the set position/distance.


I look forward to hearing from you.

Have a nice day.
