Good morning all,
I have a weird issue ongoing right now and wondering if anyone can help.
The robot controller is R30 (tall one, forgot the exact model number), M-900ib/400L. We have an SMC bock powered/controlled by the robot controller, 2 sets 24V(unswitched, switched) going to the SMC block. On the SMC block output valve bank, we used 3 positions exhaust center valve for our suction cups.
Since this morning, when entered the cell, the suction cup started to lose suction, I assume this 3 positions exhaust center valve will need the output on to maintain suction, if that is the case, what causes the switched 24V drops from the robot controller? one of the UOP signals or one of the safety over ethernet signals? If not what could be the problem, I already tried to replace the SMC output valve bank and valves, did not work.
Thank you!
