Hello,
We have an IRB 7600 with IRC5 M2004 (with older version servo driver, the black boxes). We suspected a power surge into the robot (yeah... the robot is being used in a warehouse with old power systems separated from the rest of the factory, and external power supply for other things has fuse blown). When we rebooted the robot and tried to jog, we got a very very loud screaming from somewhere in the cabinet (see attached video). We checked and found that rectifier as blown capacitors and driver has a blown capacitors, we proceed to replace all of those. But this did not fix the problem. The robot moves but very slowly and we were too afraid to force it to move We are wondering if there is anything we should look for? We suspect the drive pack and rectifier, and also the EMI filter. Should we try to bypass the EMI filter to see if it's broken?
Thank you very much in advance!
