Hi,
this is puls/direction
one option is to do it by Ethercat and EL2521

Hi edwin, did you have some example about it? I've researched in google but i still don't know how to use those device (EK1100 and EL2521). Base on your picture, i need to buy EK1100 right? But why i need it? Cause i can easy give driver pulses with GPIO of Rasberry.

Hi,
yes you need to have EK1100 and EL2521.
Using GPIOs is maybe possible depend on how fast you need to move the motor. ( and you need to convert the 3.3V GPIOs to 5V whatever your puls/dir interface is using).

We have no ready to use driver for GPIO's in combination with SoftMotion. So the only way to do it with PLCopen FB's and Robotic/Motion is to use these.
