Yang MV-3A VMC

Hello everyone,

Recently got hire by a machine shop where they have Yang MV-3A machine which I need to operate. Now everything was going well a few days ago, I could change the tool with ATC (Automatic Tool Changer) M06 MDI or program. However when I finish g code program and tried to execute the program the Automatic Tool Changer goes for the orient the corosel and the spindle, however the spindle does not go for home position for the Z axis. The Spindle would only orient on itself.

I have a Makino Machine which I know it is very different however according to how to use or change the tool we would go and tell the controller what tool is install on the spindle, in this case tool number 1 or T1. How do I know what tool is register on the spindle of this Yang VMC Machine? How do I reprogramed all the tooling from the last operator settings?

The Main problems that I am having is the ATC does not complete the tool change. When I tried to register the tool number on the controller T1 for example it gets me on Alarm Error. It sounds like the Fanuc 0-M lost the tools which had register. But not really sure. How do I reset all the tools and re-register them? How about the M06? M06 does not work, the arm does not change the tools. The machine just freezes up and waits and does not through you an error message.

Many thanks for all your help!

I have an old OM VMC that needs to be told to go to the tool change position. On my machine a tool change sequence looks like:
G30
G0 Z0
M6 T1

Go to second reference and do the tool change

I run a smv-1000, and it changes tools through a macro. You may want to look it over and make sure it's still good.

check the macro program , or the tool change is in Ladder only ??

i got a yang-mv3a rencently.... i'd like to know how to change the tool as well...do u solve it ?

Ive got a yang , eagle 600 with an OMD control .
It uses a macro program for its tool change ....maybe i can post the macro for you guys if it will help .

I think thats the tool change macro i have about 4 others that are on the machine but im not sure if they are for tool change or not .
