Hello,
In the Configuration of the SM1436-1 there should be this line were you can set up the Feedback / Encoder Link. If you set it to no encoder the system knows that there is no feedback and just generates a set value for the movement.
On the Programming Part there is no differences.
I would also hint to read the Guide which contains a lot of information about how to commission a stepper axis. The most important part is that you configure the timing of SystemTimer and X2X/Powerlink in an synchron way.
