Verify door close and open on Fanuc 21 t

[gtrrpa]

Can anybody help with the parameter that needs to be set where I dont have to verify door close switch every time I turn on my lathe? I'd like to set the parameter where the parameter is set to where the door is closed all the time.
I know it can be done. A tech did it for me on a Takisawa years back, but dont have contact with him anymore.I'm running a Hardinge Conquest now. Please Help.......
Thanks in Advance...........

Wrong place for this question. I don't think this is an employment opportunity.

No, but it IS a question about Fanuc... what make/model of machine is it? I believe the door switch parameters are in the keep relays.

look your talking about a Fanuc 21t this is a newer control and if just tying the switch back does not work then you are out of luck. machine builders have writen into thier ladders the need to see this switch toggle open and close at certin times. your older machine would not have this type of ladder in it so jumping a switch or being able to say it is not on that machine was possable. too many injuies have forced the industry to be smarter on how the door switches work .

If the machine has door switches, it would be on the PMC side as stated before. A keep relay or D data, or some just have a key on the operator panel to enable/disable the door interlock switch. Best to call Hardinge with the machine model, serial number, and control type. They could look it up very easy.

hi

like hitachibos said is a CE norm that fanuc must put on ladder so in the newer version of fanuc u can never take it out cause it is placed in many equations from ladder so u will never take it out.

the single thing that u have to do is that u can put on the exterior of the machine an extra button for check the door .

u take the wires from the door interlock and replaced with a manual button (close/open) but the operator must be very carefful with this cause u can start the machine even the door is open so should be very carefull about it.

i made it once for a client but is only on the costumer risk and should sign for this modification.

good luck

Another bad answer. Fanuc DOES NOT BUILD THE LADDER. You must contact the builder-hardinge to get the answer you need.

[zavateandu]

yeah i know for me that fanuc is not the builder of ladder but to a nuubie guys how u can explain that (some of them they do not know to read the ladder)----but yeah u must show us u are clever ---ok u did it!

and for u another bad thing is that no builder of the ladder will say to u the soulion because is """"""""""""A CE NORM""""""""""""----got it!

so noone will say to u to take it out cause is against the eurpean laws----should i draw u something?

try to play some chess in free time!!!!!

good luck!

[zavateandu]

ah forgot for u knowledge i know how to read what u said

an example for u---check picture


and u know that the faanuc sell to you the controler right?
or u buy controler from fanuc and the ladder from hardinge?and u load on controler?

oh my god how hard it is for u m8?

[underthetire]

First, CE means absolutly nothing in the US where he is. We have OSHA, ANSI, NFPA standards we need to go by. I do agree that disabling a door switch function does nothing but set the shop up for a lawsuit. Hardinge built the machine, supplied the control, and did the ladder programming. By telling him Fanuc supplied the ladder would get him nothing, they could not help him if they wanted to. Chess has no circuit boards or wiring, so I'd be useless in playing a match with you. You obviosly understand ladder logic, i'm sorry if you thought I was attacking your knowlege, but pointing someone in the wrong direction is not the answer.

[zavateandu]

yeah m8 istay cool i am not supsad but was the easiest way for him to understand and i did it in my way to do it.

also i said CE cause for me is he same like in US is a security option---is the same man so no security operation option will be removed by builder--agree?

all this kind of traps u have to do it in u own risk(here is door interlock but are many)

in rest peace man and have a good day to you also!

Didn't think this would get so many replies......... Thanks All
