DM430 C1P12 DigFeedBack
« on: July 12, 2024, 12:08:29 AM »
Hello,

I use DM430E and C1p12 as output but the DigFeedBack is special.  I use my feedback to tell client if the load is disconnected or not.

I use this logic in picture enclosed.  It's working but not as I want.
As example when it's working and the load is disconnected, my feedback stay 0.
As example if in the beginning the load is disconnected and output is on my feedback is activated but when the load is reconnected my feedback still activated.
It's normal because my logic is limited by this DigFeedBack.

I hope Danfoss find solution for this problem.

Please have you other solution to use feedback without using an external signal.

With best regards

The output pin is working as it should according to the pin description and what you are explaining is occurring.

I think your interpretation of how it operates is not correct.

Thank you to replay me and sorry for my English.

*****The output pin is working as it should according to the pin description and what you are explaining is occurring****
Sorry I took about DigFeedBack.  As wrote in description: it's true when output is activated and when output is open.  So for both case is True.  How can you do test?

For that I did as showing in my picture.  My logic is working as I told you when the output is on at the first time. After that if the load broken or disconnected my feedback cannot change.  I hope you understand what I mean.  I think if you do test you will understand me.

Normally when we use Output Multi function the FeedBack is current from load.  It's easy.

here you took about my logic or DigFeedBack ????

Any way, Please could you give me your feedback logic?

Thanks in advance for your help

With best regards

I don't think you can achieve the logic you want with this type of pin feedback.

Maybe you can utilise an Input configured PinConfig = 1 or 0,
Then determining the voltage on the input pin with the load connect/disconnected and output pin On/Off state.
