Hi,
i have some problems with an old MRC robot (European model). It wasn't used for more than 6 years and now it give me some headache. I don't have much experience with this the old motomans and only have some basic knowledge of the NX and DX machines.
The robot did't start, so I made a reset on the MCP01 board. (there was no other option.. it started directly on the maint. mode) I think that wasn't clever, because all settings are deleted?
I made a full backup at that point, but it seems that all position-data are written to zero.
-> Did I mention, that I don't have any backup or electrical drawings? And yes, I am totaly excited about it!
Anyway.. my next problem.. when I press servo on, only one of the two big contactors is switching. After a short time the error 5390 appears, I think because the servopacks are not energized. I spend a couple of hours to find out, why the second contactor isn't working. Remember? No drawings? What a fun afternoon!
On the MTU02 unit are two bigger relais with two leds "SUMX1" and "SUMX2". Only the SUMX2 led and one big omron relais go on, when I press the servo-on button.
I (tried) to check the MEU01 safety card.. there is no red led and the e-stop signal seems to be ok.
So, why is the second relais not working? I traced the connection back to the I/O Rack MBB02 but I don't know how whats happen there.
I will be very grateful for any tips or hints!
Greetings, Phil
