Easimill 3 overcurrent

Post by BaBa » 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.
