Need Help!- Takisawa TM20 Fanuc OT control

[tano]

We buy this machine,we instaled and now we have a problem,spindle dont start.Machine goes to ref.points(x,y,z), tool turret works but only spindle dont start.What are conditions for starting the spindle.I check the chuck, clamp unclamp works fine.In diagnostic parameters when i clamp-unclamp 0-1 change.
I dont have any manual or wiring diagram
Can someone help?

There may be one or two proximity switches on the chuck cylinder to verify chuck is closed correctly. Also, there may be a door interlock switch which inhibits spindle rotation with the door open.

Tano:

Have you tried checking the ladder on the screen to see what signal do you need to turn on the spindle ??? I seems that it is only a condition that doesn not allow the spindle to turn, like chuck open/close, door close, lub. oil, etc. this all you can see in the ladder.

I try to see in ladder but the ladder is not complete.When i open it on the screen ladder apears but without all signals,tags etc.I think that was blocked by parameter 0060 but the value of this bit is 00000110.Any ideas?

[tano]

On the chuck has two senzors.When i open the chuck one of the senzors lights up and when i close the other senzor lights up.On the door also has two switches but they works fine.Any others ideas?

Try adjusting the bright of the CRT, if you see only lines it is possible that adjusting the monitor you will see the rest of the video.

Did the machine have a barfeeder on it?

hi
u tried to rotate with chuck open?

some of these machine has a key to clamp from inside or from outside
u close the chuck but maybe it sets to clamp from outside and is not start.

is just an idea maybe is set to start with chuck open---it means clamp the piece from inside like a ring.

GOOD LUCK!

Thanks GPena
Now i can see the LADDER but don't know how to use it.How can i find what signals i need to turn the spindle from the LADDER?

[tano]

I try it ...any other idea?

Machine now don't have bar feeder but there is connectors for bar feeder.On one of the connectors someone make bypass with two wires.On the other connector cable is cut.When i pull out the connector with cuted cable machine "not ready" appears.

Then my guess is someone had a barfeeder on it and tied in to the chuck signal or SDU. This is somewhat common on some barfeeders to keep the chuck from rotating without the barfeeder in normal condition. You will need electrical prints and someone who can read them.
