Easimill 3 overcurrent
Posted: Mon 12 Sep , 2011 16:16 pm
I recently got my hands on a 1986 Easimill 3 240V varispeed.
The problem i am having is a spindle overcurrent ,shows as a spindle fault on the screen and OC on the KEB combivert.
Has anyone got diagram A3-200079 and 80?
I think they will be similar to 59 and 60 but not sure.
I have checked the motor resistance from the KEB each phase is 3.5 ohms and insulation resistance is ok.
Should i be able to get this reading thru the contactors when the machine is not powered or do i have a problem with a contactor?
The guy who sold it to be insists it all worked before i took delivery so i have to assume somthing has died during transport, all three steppers the screen and keyboard seem to be working ok.
I want to get it all working before i start conversion to mach 3, any help you can offer would be great.
