Current Out Channel (COUT) Feedback

Steven Park 4 weeks ago in IQANdesign updated by Gustav Widén (System support) 4 weeks ago 2

Hi,

I am fairly new to IQANDesign. I am using MC43 to control some hydraulic valves and COUT is used to control one of the Prop coils. I would like to get feedback on the output channel to make sure it is reaching the target output. For example, if the output is set to  500mA, I would like to read the feedback that shows the current level at the moment. Is there a way to access the feedback without using another input channel?

Hi Stephen, you can use an Internal Channel to read the Current.  You can also display the current on the screen (if using one).

You can setup a Measure Channel to display what the output is.

Here are some tutorials that perhaps can help.

The value you see on the COUT channel in IQANdesign is the commanded current. The current regulator of the COUT is very fast, so this will quickly be very close to the actual current. 

If you command the COUT with a current that is higher than what is physically possible to drive through the load, the COUT will indicate this with the status saturated.
