I am writing to you because of a problem I have with the 880 inverter, I already integrate it with dcs 800x.a, check the parameters in the inverter and apparently everything is fine, I can send feedback to the inverter and I see it on the inverter screen but when I send it the command to be through the face plate does not start, I see that in one of your answers you mention that for the start and stop, the control word has a precise bit within the set a1 to get the desired function, could you give me more detail about that, I forgot to say that the communication is via profibus dp. I thank you in advance for your answer.

in addition to the link of my old answer, to try to solve the issue you need to verify:
to have correctly set the drive parameters to operate with profibus
to give via DCS the correct command - control word - to the drive, generally you can try one Variable directed MOVE to the control word.
The most diffuses commands are (decimal format) - 1150 to stop the drive, 1151 to start the drive, 1143 to stop in ramp the drive, 1152 per reset del drive
Hope this help you
