Attached is a plan for switching the relay DO2 using settings in P2155, also included is adjustments for Hysteresis and delay time which is useful.

To get a view if the parameters I have used Siemens 'Drive Monitor', vis a RS 232 / 485 converter, whilst not essential, most but not all of the parameters can be seen and changed on a PC. I do not believe there is a PC base configurator for V20 yet?

Also: Micromaster MM440 issue 10/06, this is an old manual, still available for download, but useful for getting a look at the V20 parameters as they are similar, and some of the drawings are better.

 See how this works, and come back if you have any snags with this.

Hi

You said:

I need a system in sinamics v20 where when my analog input A1 is above 75% I activate my digital output DO1, is this possible using the BI-CO parameterization or something similar?

It looks like I have misread the question, and provided a method of making the digital output at an output frequency??

Please let me know if what I have provided is OK, as I am sure what you specified can be shown too.

Hi,

See attached version, to use CMP function to monitor the analogue input, I have used the relay to monitor the operation.

Yes, I find Drive Monitor useful to get into the V20, but as as been pointed out it is not 'supported' as a 'tool' by Siemens.

See how this works, come back if I have missed something.

Thanks for the feedback
