Never mind, I found it. It was in menu offset button.
Thanks again, Rich

No, I didn't command a feed rate. The grinder manual says its variable macro #500 and to consult the fanuc operators manual which I don't have. How do I set a federate?

Any help on an alarm 11. It occurs when trying to do taper in automatic mode(forward or back buttons) the taper works fine if I crank the handles but not in auto mode??

Correction......The multiplier is working just not in the same ratio it did previously. On x1, 1 turn on the handwheel =.001(inch) and x5 =.005 and x10=.010. It works fine this way, just different...

I found that 8203 parameter was incorrect. I changed it and now the vibration is gone. And I found that the limit switch(deceleration)was set incorrectly for the x axis. The machine now homes!!!!...

Opps, I was wrong, it gives an alarm 90 when doing a zero return in the x axis. But it does move nice and smooth in the x axis as compared to the y.

Yes the x axis seems fine. The y axis seems to vibrate when you jog it. Then as soon as you move it fast, it kicks the alarm. I"m thinking the servo needs tuned for the y axis?

With those parameters input, when I try to home it. An error 426 (y axis disconnect) comes up now. I'm going to try taking the servo connections off and cleaning them with electrical contact...

What are the parameter numbers for the y axis. Its a profile grinder and only has x&y axis.
Thanks again

Parameters 21 and 22 are all zeros.
When trying to home it gives a 501 error y overtravel alarm but it only travels .075(inch)
And if I go in the other y direction, it only goes .075 that way and...

No alarms. All the diagnostic parameters except # 500 thru 509. I was able to input those. Machine won't home.

Yes it is enabled. I've entered all the NC parameters and now I'm trying to enter the diagnostic parameters and that is where it only allows me to enter parameter #500 to 509? Please help!

my fanuc om will only allow me to change/input parameters for #500-509 using the procedure above. Any ideas how to input the rest of the parameters?

I'm working on a wasino profile grinder with fanuc om controller that lost its memory. I input the nc parameters and tried to do the pc(diagnostic) parameters but it will only allow me to imput...

bump

Today it won't home in x-axis. Error 90 and then 511 overtravel. I tried the fanuc memory restore procedure and can only get to step 6 where it says to select EDIT mode. It won't allow me to...

I'm working on a wasino 135as profile grinder with fanuc om controller. I believe that the backup batteries were changed and lost homing program/parameters. When I try to home the machine , it...
