Dear all,

We have a Wire EDM machine – Matra Robocut α00, 1998 model, Controller Fanuc 16W.

We brought this used working machine from another company 100km away from our company. When we installed the machine in our facility it was showing error alarm 401 uv . Pls use below link to see the details

To solve Alarm 401 problem we purchased a refurbished UV axis drive from China and replaced it. But it didn’t made any difference . We were getting the same alarm message. When we conveyed this to the repairing guy and he said then the problem will be in CPU. Then we send the CPU to them for repairing . They repaired the same and told us they changed two boards A20B-2902-0341 and A20B-2902-0070.

After fixing the CPU back in the machine, we could not load the machine parameter.

Pls watch following video by using below following link to understand the current status of the machine
