Hi
as I have been able to tell you, the description of a problem, if you want someone to try to help you, must be as wide as possible and with all the possible indications.
For starters, have you made the correct settings for the ModBus communication in the ACS880 drive?
The image below shows you the minimum options you need to set ... did you do it?
You must be sure that the communication speed is the same between your master and the drive ...and the node is correct...
As regards the composition of the control word, the value of hex 47F is the sum of all the bits that must be at 1 when you decide to run the drive. The ModBus manual can provide you with more information in this regard.
Hope this help you
