Hello, we have been recommended a Lexium 28 servo motor and I'd like to use a M221 to control it. In this example, the velocity is set to a constant value, is it possible to use a memory word instead? I can't find how to do it, it won't register my "%MW" input...

Hi,
You can use an Operation Block to move values from a variable to the Velocity as below:
Note that you must use the instance of the FB (dot) Vel or any other parameter.
In this case, .Vel is a DoubleWord and therefore, must assign an %MD
You will use the same for timers, counters, etc.
