Wiring

 
Resolution:
When you are using Unity Pro with an Altivar AC Drive and CanOpen, if you write to ACC or DEC the PLC sends a 0, drive doesn't understand the command, and performs factory resets everything except what's written to the option module. Also, you have to disable the Bootup Procedure, which by default will write all 0s to the drive which factory resets it.  Need to configure per attached.
