We ordered a new VSD ATV950D75N4 to replace VFD ATV71, so no experience ,When we configured ATV950D75N4 for all parameter to match with motor then configure communication parameter same as original with Modbus TCP network and IP address,It can be communication to SCADA but can't operate motor such as start/stop. And when we turn OFF power and ON, the communication type it change back to default "Ethernet IP" ,Then impact to our network,
How to solve this problem ?Please guide me on this if anyone knows.
Thank you very much,
