Are the drives powered up.

See if you can turn the X axis leadscrew or if the motor is holding it.

I' ll try tomorrow. I don' t understand ... before BALDOR card should fail everything was ok.

I can turn on the coolant.
I can turn the spindle.
But I can not do the homming.

When I try homing, I can turn the X axis leadscrew the motor isn't holding it.
What I do?

check the supply to the drive psu, probably fuse 4.

Posted: **Mon 26 Mar , 2012 13:51 pm**

I had already checked, it's ok.
Help please!!!!!

Are the drives powering up ? Any LED's lighting up on them - you will find the manuals for those here on the forum:
Parker I think: viewtopic.php?t=561

It may be that when the Eurocard failed, it caused a failure on the rack - maybe also the drives as they share the same backplane.
Check around for burnt tracks/fuses on the rack system.

on that model, does the second board next to the baldor board supply dc to the control logic, or enable the drives somehow.?

Posted: **Mon 26 Mar , 2012 14:38 pm**

AFAIK the 2nd daughter board is just additional IO and the isolated spindle analogue

I don't remember seeing or scanning any information on that card

Posted: **Mon 26 Mar , 2012 14:39 pm**

Eurocard failed probably because I replaced the battery with a wrong.

Before everything was ok just could not remember the tool.
Fuses on the axis cards are ok.

is there 24v on the drives

Posted: **Mon 26 Mar , 2012 14:52 pm**

If the drives aren't been energised then you need to trace that fault from the diagrams and the manuals.
eg:
viewtopic.php?f=54&t=3068
viewtopic.php?f=54&t=2264

Is the enable signal changing when you release estop - I'm not sure what will exactly happen but power should be applied to the axes drives...

Posted: **Mon 26 Mar , 2012 15:03 pm**

the 24volts DC is present on the backplane. wires 60 & 61.
I checked the 3 x 20mm fuses on the backplane and are ok

Posted: **Mon 26 Mar , 2012 16:01 pm**

make sure the drives are fully pushed into the sockets.

Posted: **Wed 28 Mar , 2012 8:00 am**

When i try homing the X axis baldor card writes "H"
When i try homing the Y axis baldor card writes "8"
When i try homing the Z axis baldor card writes "8"

I checked DC on terminals shown on the picture: is not present.
I checked all fuses in the axis card and in backplane: are ok.

Posted: **Wed 28 Mar , 2012 8:44 am**

It may be worth checking that the ribbon cable between the custon card & motion control card is fully seated.

Posted: **Tue 10 Apr , 2012 16:43 pm**

YESSSSSS!!!! I did it! :fireworks:

The machine works!
The fault has been an abnormal contact of a fuse on the backplane!
Thank you all for your advice and thanks to Denford for the support.
