Hello, I have a Yuasa AccuMill AM-1475 with Fanuc 3M-Model A Controllers
I was setting up to run a job today and in the process of returning the Z axis to the reference point I encountered the following Servo Alarm:
SV Alarm 02 - The READY signal (VRDY) of velocity unit has turned off.
I turned the machine off and turned it back again only to get the same error when returning Z to reference point.
Once I turned on and off the machine for the second time, I was only abele to move Z in the negative, down, direction. In the process of trying to figure out what’s going on the Z axis ended up at -6" which is the over travel limit. My Z is now stock in that position and I can not get it to come back up, even if I hold down LIMIT SWITCH RELEASE.
A NOT READY ALARM is always flashing at the button on my CTR and when I hold down the LIMIT SWITCH RELEASE button I am able to move X & Y but I constantly get a ALARM flashing at the button of the screen and Z axis is stock in over travel.
Can any one help me out?
Thank You
Adam
