We just got a 4 axis Takisawa MAC V4 with a Fanuc 6m controller. We had it powered up and moving the other day, but today it is having issues. First, all axes except for Z moved and homed out properly. I tried restarting it several times, but the z axis would still not move. Then shortly after, the rest of the axes followed suit and all stopped moving. If i hit the jog buttons, you could feel and hear the X and A axes thud a little bit, but nothing really moves. There are currently no alarms, but earlier i saw a servo alarm 401 and 403. However, the machine was sitting on the limit switch at the time, so i suspect it was just that. The alarm hasnt resurfaced since it was taken off the switch. The other weird thing is that previously when first powered up, the position screen showed a random position such as X12.4563 Y4.2456 Z12.5452 A120.45 (not the actual values, but you get the idea). Now it only shows X0.0000 Y0.0000 Z0.0000 A0.00, and that doesnt change at all, no matter what we do.
Does anyone have any ideas?
Thanks in advance!
