Our Okuma MX-55VA mill is having some connectivity issues on one of the fieldnet units (randomly crashes with a bunch of unrelated errors all tied to one connector on a specific fieldnet unit, sounds like a bad soldering connection).
I wanted to take a system backup before removing the unit, so I consulted the maintenance manual.
The Okuma maintenance manual stated that to enter the system backup menu, I do the following:
1) Turn on the control
2) Flip the switch on the front of the UCMB to "Install"
3) Press the reset button on the UCMB
Flipping the switch was fine, but as soon as I pressed the reset button, a couple of relays clicked and the monitor just shows strange colors. All the run lights on the UCMB turned off, but the power lights are all fine.
I was worried, tried restarting a couple of times but it looked like the machine was dead. Then I showed the problem to someone else and magically, the UCMB unit turned on normally and the machine worked again.
Okay, I was out of time yesterday, so I went home.
I still need to take a system backup, so this morning I did the same procedure again, but now after the reset button the UCMB won't run when the control is turned on.
I don't see any relays that need resetting, and I can't tell what may have happened, but it sure seems like either the manual is incorrect in the order of operations or there is something wrong with the UCMB unit.
Anyone have any solutions that might work to get the machine back to life?
