haas m code

[heartlnd]

we would like to use the m08/m09 function to turn on/off air on our haas mill.does any body have a lead on how to do that.we have no wiring diagrams for the machine at all.we would like to use a 24V solenoid valve between the air supply and the spindle.it is not an airblast,but continous air flow to the spindle until m30 is activated.any help would be greatly appreciated.

You could wire a relay in to your coolant pump circuit disconnect the coolant pump and use a step down transformer to run the 24v solenoid. Than you could use m8/m9 to turn the air off and on. But Im sure haas has some extra m functions that you could plug into to achieve the same thing. Give them a call I've found their phone service excellent.

We need a more clear description of what you want to do and why.

1. What is your machine model?

2. Is this the main air supply to the machine, or some kind of blow off nozzle? I suspect it can not be the main air supply or you would have turret and other problems.

3. Are you still going to control coolant? In other words do you want an air supply for something that is precisely synchronized with the coolant on-off function? If precise sync is not what you really want, then you can control one of the aux output relays.

Search for the string
m21-m28
in the HAAS on-line manual 96-8000.pdf

These M-functions control control optional user relays.

See also "M51-M58 Set Optional User M Codes". The corresponding relay set on by one of these remains on until reset my M61-M68.

the machine is a om2 office mill.the coolant pump is not needed.all i'd like to do is turn the air on when the spindle starts and turn it off when the spindle stops.i know we can use a solenoid to do that but the wiring is the issue here,since no diagrams came with the machine at all.we've read the maual but that still does not tell us where to get the correct wireing points from.

thanks for all the help

I have a vf3 and from what I can see it looks like Spindle drive unit (R)to 230 vac to Part of power supply PCB (CB3) to I/O PCB (k6) to coolant motor. Perhaps this is not what you needed.

Make a small program like this:


N100
M08
M09
GOTO 100

Single step thru this and have someone watch in the enclosure for an LED to change state or hear a relay change. I believe the relay will be electro-mechanical.

To exit the program do a reset.

I think you would be better off using one of the User M functions which give you a low voltage relay closure. However, maybe the picture will help you identify the overload breaker that is on the board for the coolant pump. I think it is almost certain it is installed and that the wires are there but simply have not been connected to any socket.

In two of my manuals, 93 and 96, the coolant relay is K6. Looking in the panel I can not find it. It might be behind the cover where the coolant circuit breaker is located.

If you use one of the user relays, as Geof suggested, then you won't have the front panel push button to control your air valve.

If the function of this pushbutton is important to you, then find the output connector that would have gone to the coolant pump. Use this output to control a relay to control your air valve.

On our machine the connector is an Amphenol 97-3102A-20-15S. I believe this is the number for chassis connector on the machine. You would need the cable mate to this. It should end in a 15P (plug) I believe. Pin A and F are the 230 V single phase to the motor. C and D probably have to be shorted to indicate OK coolant level. G is the ground lead to the motor housing.

I have not power the machine and checked the two Phoenix separable terminal blocks below the coolant circuit breaker for voltage controlled by coolant on and off. But logically these look like coolant motor termination points.

If your machine is 230 input and that is what is switched for the coolant motor then you need a 230 V coil on the relay, or a 230 V coil on the solenoid, or if you use a 115 V relay coil, then you could put a series dropping resistor in series with the relay coil to reduce the 230 to 115 at the relay coil when it was on. I would not suggest a series dropping resistor to the coil of a 115 V AC solenoid valve.

Geof's board layout is different than mine where the circuit breaker is located.

....Geof's board layout is different than mine where the circuit breaker is located.....

Yes I didn't mention that is a 2005 machine, the OM2 Office Mill is a recent machine so it should be similar. I have found in all my machines that wiring for options is preinstalled and just tucked away out of sight when the option is not implemented. This is why I suggest looking for it.

hi guys first of all thanks for all the help.
this is what we worked out yesterday.we could use the water pump to make it work,but then we saw that there is a pickup point on the main board for air blast P66 which can be activated with m57 on m67 off.
what we don't know is how to get the power off of the board since we have no diagrams.what we measured un the board socket was 70V DC is that correct? also what is the max current all this will help us getting the right solenoid valve.
thanks again for your help

hi guys

we got it working.bought a solenoid and used the waterpump cirquit to make it all work.thanks for all your help

Way too much work should of just used 2 of your 4 spare M codes or ordered the auto air gun!
