So an update on this. We have now replaced the ballscrew assembly and x axis bearings but still having the same X-axis pulse alarms with A607 and A608 error cods on the drive. I've swapped the x+z...

Correct, we have replaced the insert, all looks good there. The ball screw moves easily when turned by hand. The motor and drive were sent to Global Electronics for diagnostics and repair. I was sure...

We were speculating that the bearings may be causing some of the feedback. We also have an Arrow 1000 which as the harmonic balancing pack on the end of the ball screw and when replacing the bearings...

We ended up swapping out the realtime board with a spare we had. Seemed to possibly be an issue with one of the other cards fitting loosely into an ISA slot on the board. We were able to trigger the...

This machine is an Arrow2 750 (Acramatic 2100) with Siemens drives.

We are having an issue related to the x-axis drive

With the machine cutting or even sitting idle after alignment - we get an...

Scratch that, still have encoder errors just seeing the "spindle not at speed" along with them now.

I believe we have resolved the C,X,Y,Z encoder issue. The plug to the power supply near the realtime/DV5 boards was loose... After roughing for a few hours it was coming lose to the point where it...

After a little more research I think they are Kollmorgen based drives. The machine does have scales but when it was installed (used) the scales were disabled and motor encoders used due to an issue...

The machine is a year 2000, Acramatic 2100 control. The drives are light gray and blue. We are located in Pittsburgh, PA.

We have an Arrow 1000 with Vickers drives. We have been experiencing intermittent fault which caused the machine to shutdown.

We get 44-52 C Axis Encoder Error, X Axis Encoder Error, Y Axis...

Recently started getting an intermittent alarm "NCA. Carrier Drop". The machine will make a "toot" or whistle noise before the fault. I have a feeling it has something to do with power to the machine...

Upon boot up, while loading “Loading Machine mode (3 of 13)” it hangs for a minute or so then gives the following errors:


“Application startup timeout. The exe name is CNC.EXE”


...

Ended up being something corrupt on the drive. I put in the backup CF card and everything works as normal.
