I have a following issue with this old variable frequency drive. All I need for my porpuse is to download the program stored in vfd. The problem is, that CeLite or DSElite cannot connect to it. In case of Celite I recieve tha following statement:
Error #6453: Serial Comms failed (slave EOTed). (unknown mnemonic)) reading PNO II
also I don't have a MMI to provide local control so everyhing depands on communication via port P3 with PC.
So do you have any suggestion how to properly download program from vfd ? The vfd looks functional, according to status LED's is in stop mode.
Thank you for any suggestion
