I see. Thank you so much for your help.

Thank you for your answer. Is that the reason why the actual current signal always is zero? So can I get the actual current information directly from the drive instead of from the PMAC controller?

I am using XGT servo AC servo drive (XDL servo motor). It was installed before I came my lab so I just use it. I don't know exactly what is the command signal from the Clipper to the amplifier. How can I check it? (So sorry about my ignorance)

I am not sure what exactly is my Clipper Controller. I just know that the PMAC is Clipper. Maybe it is not what you mentioned and that's why the actual current signal is always zero in my system. Only the commanded current varies when I move the motor.

Thank you for your suggestion. In my configuration, it is Mx02. Do you know how to access it from LabVIEW (PMAC panel) for further processing?

The current control is on the Clipper. The signal then is transferred to the amplifier. I know that I can get the plot with PMAC Plot or PMAC tuning Pro, but it just gives me a graph. What I need is a variable which I can get/access to process it.

I am using the PMAC Tunning Pro to plot the Command and the Actual DAC/Current to my AC servo motor. The problem is that in any case the Actual DAC/Current is always zero and only the Cmd. DAC/Current changes in different conditions. Could you please explain me the reason. Also, I want to access to the Command and Actual Current value for further processing (such as calculating the motor torque). How can I get these variables? I am using PMAC clipper controller.
