Yesterday I got 2 faults at the same time on the teach pendant. Alarm 4386 Check error CPU 1 and Alarm 4393 Check error CPU 2. I had read what was already posted about 4386 and investigated to no avail. I can not find any information on these on the net. All wiring is good and the fault reset. I had it again today. Any info would greatly be appreciated.
Thanks
