Haas Door Hold Override

[savagkd]

Hi All! It's been a while.

 

Anyone know if it is possible, on a Haas mill, to togle the door hold override on/off in the NC program.

 

Thanks

yes, change setting #51

 

 

oops, just noticed you said in program. sorry

[savagkd]

sOK. Thanks anyway.

I have Haas service here and I ask them and they said no it cannot be done in the program.

[savagkd]

OK. I guess we'll have to figure out another way.

 

Thanks.

If you want to do a little wiring, you could break the wiring to the actual switches on the doors and run them through the user M-code (M54,M61) relays. I would use the M54, M61 because it just flips the relays on or off, M21 probably would not work here because it waits for an M-Fin signal. There is some tech info in the Technical section of the manual and the connection points usually are pretty easy to find in the panel.

 

We use the user M-codes for tool break detection (we do not have the probe) and we have a bell that we activate at end of cycle. You can hook up all kinds of things really.

Can I ask why you want this in the program instead of toggling off when you start the machine?

I am guessing he wants to unlock the door at the end of the program or at a program stop. Our Mazaks require the operator to press a door unlock button to open the door. Our Mori does too, but Mori was smart enough to add code to do this at the end of the program. I cannot get Mazak to change it and it's very annoying.

You could just unscrew the lock from the door....

Nope, we don't do that. Now, Mori is smart, they have an interlock release function that allows operators to do limited stuff with the door open and it works great.

 

The interlock is on the machine for a good reason and we keep them on. It's also an OSHA violation to remove them.

Once you toggle it off at the machine it stays that

way till the machine gets turned off...right?

 

(Hass anyways)

This whole thing is over an operator overriding the door hold so he could run with the doors open. It cost him a trip to the doc. We want to turn the interlock on at the start of every NC file. That way if the interlock is overriden for set up, they can,t forget to turn it off. Hope to save the next guy that trip to the Vet.

 

Thanks

But wouldn't the door override be turned back on as well during a set up then? Sure they could add it to the program after the set up but why not just remember to turn the parameter back after the set up is done.

The Yasda has a double key set-up! What a pain in the rear!

Eric, I wish that all would remember to turn the override back off after set up, but I have to admit; I've forgotten myself.
