It looks like P13 & P26 want reversing for the X axis.

You are commanding it to go in the + and the display confirms this, but phyisically you are moving in the opposite direction, right?
This is usually a parameter bit set to a 1 or -1.
I would have to look up the parameters for the 8055, is the 8055i a PC based control, by any chance?

This maybe the parameter in your file MX1 that needs changing? (This is for a 8055M)
AXISCHG (P13) (AXIS CHanGe)
Indicates the counting direction of the feedback signals. If correct, leave it as is. If not,
change it from NO to YES or vice versa.
If this parameter is modified, parameter “LOOPCHG” (P26) must also be
modified so the axis does not run away.
Possible values: YES and NO.
By default, the CNC assumes NO for this parameter.

Sorry to repeat, time delay.
Great minds think alike.
I show the P13 & P26 in the 8055i manual.
Loopchg reverses the analogue signal, so now the motor will now run in the opposite direction for the + command. So the feedback must be reversed by the Axischg to again count in the right direction.
That is the way I interpret it.

My post is a direct quote from the Fagor Manual
Ok gentleman, we are making some progress. Par. P13 and P26 were both NO. We changed them to YES and axis movement and the readout were correct in X. However, it would overtravel when trying to home the X axis.
Where is the home switch location on your mills? The physical location of our switch is on the left side as you are standing in front of the mill. I am thinking that if I move my switch to the right, all will be well. Or could I do that with a simple parameter switch?
Thanks.
By the way I read it you should change P26 back to NO to have it home in the correct direction.

We put P26 back to NO and it did not change. We are going to lie to it and change the home position and see if that works.
Suggest you also check P5 and P6
These set the software travel limits.
P5 = Maximum, P6 = Minimum.
I don't think it matters where the switch is mounted as long as it gets triggered and the parameters are set to suit.Originally Posted by 5th-axis
For the Limit settings my Fagor controlled machine with a 'X' travel of 800mm has P5 Limit+ as 777.5 and P6 Limit- as -23.5
Just a thought.
If your P5 Limit+ = 500 and P6 Limit- = -300 I'm thinking these may need reversing?
eg. P5 = 300 and P6 = -500.
Could be totally wrong, just offering a suggestion.
Gentlemen,
We can put the Fagor problems to rest. After changing the P13 and P26 parms. the issue is resolved. We did end up moving the home position switch to the right side of the table. We could not change this in the parms. no matter what we tried. But the control is functioning as it should thanks to you fine gentlemen. Your help is greatly appreciated. Maybe one day I can return the favor.
Good Luck
