Chris,

Have you been running this machine for a while, or

is it new? Double check your air pressure. We have 2 vf2s. Im not gonna be much help. I just looked in our manual which I am sure you already checked out. Our parameters for 67 is 9000. for parameter 70 is 50, and for parameter 75 is 30.

Also talks about a circuit breaker cb4.

I dont know if this will help, and how the vf6s cross with the vf2s. At least the error codes are the same in the manuals!

We have the same problem on a haas vf2, so far the service techs have not been able to fix the problem, which usually occurs at machine start up. The last Tech that was in here said to unplug the air line from the machine and plug it back in while the machine is trying to find high gear. This works on our machine.

Here is the quick fix that we have done on all of our machines.

 

On the return line that comes from the tool release piston on the front of the machine (it is the 1/4 plastic tube that runs to the right NOT the 3/8 that runs on the left!!) we drill a small 1/8 hole to help the machine keep from developing back pressure in the air selenoids.

 

So far we cut back on both tool release faults and also shifting problems.

 

The line on the left is the pressure line so be careful not to drill the wrong one.

 

If you are in doubt remove the air from the machine unconnect the right side then reconnect the air. It should NOT be leaking air. If you disconnected the pressure side (left)it'll be leaking air like crazy! You need to put the hole in the one that is disconnected and not leaking air!

 

What happens is the tool release bleeds air into the selenoids in the back and it is suppose to keep oil from building up there, it would probably work if the oil had somewhere to go but all it really seems to do is build perssure which is why disconneting the air from the whole machine works as well.
