Hopefully yall can help me out. This is a new drive (installed by someone else) on a previously running piece of equipment.
Customer has a Parker 590 DC drive hooked to a 200hp GE motor (shunt field).
When i got here the field feedback was 0. I discovered the field was disabled in the drive. Once i enabled it I get a "Field Failed" alarm. Manual says this indicates no field power or an open field circuit.
I have 480v on the field control input and 60ohms of resistance on the field circuit.
Im waiting on Parker Techs to call me back, but I'm hoping someone can point me in the right direction.
