text: <s>[INST] What's the function of IAM and AM. Summary: Thay both are axis module,so what is the difference?Could you expalain what of their function.It seems to be difficult to find some detailed doc. to focus on it. [/INST] The AM Axis Module has connections on the front for motor, encoder, and auxilliary IO. It draws its power from the power rail. The IAM Integrated Axis Module, in addition to the connections noted above, has connections for input power and control power. The IAM has the converter which takes input AC and turns it into the common bus DC used by all the modules. There must always be an IAM on the left side of the power rail. And before you say it, I agree with you, Rockwell could have picked a more descriptive, intuitive name for the IAM. TJ McDermott \\n </s>
