Does it make the same sound during a program? I wouldn't trust the sound the machine makes during handle jog, it can be very abrupt sounding.

Do you have backlash in your z axis?
You can set up...

You have to watch for special characters to *@#$^&% ect.... Same thing will happen.
It is documented with Haas, they know about it.
I'm sure they are working on it, and will fix in a software...

Definitely a processor problem. You can try cleaning, but usually a processor is needed.

I've seen a company with 4-5 vf2ss with a rotary on each. Making these parts 24/7 for the last 2-3 years.

The control is looking for 145-175 range for DC buss voltage. It's not the output of the power supply, its the monitoring of the voltage. You have the correct voltage out put, possibly too high,...

I don't know what the Cap is for. and haas doesn't give out schematics...
Either there is something wrong with the power PCB or the Motif that monitors the voltage at the power PCB.

What is the Control Displaying for Voltage, when you have 176Vdc at the Cards?

On the older cards you can adjust a pot, but it looks like you have a newer Card and it doesn;t have anyway to...

There is a DC BUSS power card next to the servo drive amps, this is where the DC Buss is coming from. IF the DC buss is changing this usually the culprit. Does the measured DC Buss match the DC...

You wouldn't have to drill a hole thru the spindle, but you would have to replace the standard drawbar with a TSC drawbar (which would have a hole thru it) and would need to modify or replace the TRP...

If you have 8 series software you can upgrade to 9 series. But you must have 16meg of flash memory on your processor to run 9 series software.

To check this, power off the machine. Hold...

Are you having a problem with the machine? Why were these values changed to begin with?

The values don't have to be the same for each axis, each ballscrew/motor/ect will behave differently and...

There is a temp sensor in the control cabinet. If the control gets warm the fan will come on. I would trace the fan wiring back to the Power PCB and move the plug to a 90C plug on the PCB, should...

I have seen this before, and in my case it was the actual Magnetek spindle drive that was clicking (relay sound) during start-up, and sometimes during running. I replaced the drive.

The 123...

To have your software updated from 15 to 16 series software does only take 15 minutes if you have enough Flash memory on your processor. The 16 series software requires 16 meg of Flash and some...

You have to adjust the grid offset (par127?) correctly first before setting up your Tool change height (par 64). Otherwise you will get zero-return margin to small or Large alarms.

The Servo's have to be on to measure the DC Buss voltage correctly, so there can't be any alarm/e-stop ect.

It could be the mocon board, that would be the board that would send the 5v signal to the drive, but there can also be something dragging the mocon's 5vdc down. Possibly a coolant level sensor? I...

"They replaced a couple amps and a 12 v powersource, but that was to correct 104 and 105 alarms. This new problem has no alarms and locks up machine. Has any one out there experienced this??"

I...

X-limit switch sticking more than likely the problem.

I would take the cover off the monitor and put a fan blowing on it, and see if the problem goes away. Sounds temperature related. Adjusting it will not work, or it will work for a few minutes and...

Sounds to me that you may be looking at the spindle lube regulator and that would normally be set to a lower pressure by a small regulator.

"For testing purposes only" change parameter 76 to...

Do you have dual windings, it almost seems like when it "shifts" into the higher winding that the noise goes away. If you go to the diagnostics page and look at the D:Y bit on the Lower Right side...

It would be very hard to remove the gearbox pan with out at least raising the assembly up some, and it would be a lot safer to just bring it down and on the ground at that point.

Haas offers a 50%...

If you can handle jog the z-axis lower (to the position that you need), then its not a parameter problem, there is something wrong with your program. If you are trying to move the machine past its...

When you run without the belt on the machine do you still get the same noise?

How is the spindle load when you are running it? should be steady.
I have seen when the spindle motor parameters are...

You can enter debug without pressing the e-stop, but the parameter lock has to be off.
And when in debug you can change parameters with out hitting the e-stop. Can be dangerous if you are not...

ALSO YOU NEED AIR TO GET LUBE TO YOUR SPINDLE.

DOES IT SCROLL THRU ALL THE COLORS? AKA, YELLOW, THEN RED, THEN BLUE?

If the machine is new enough, I don't know the cut off, but if you get into debug mode you can see the history of keystrokes. This may help see if it really is a key "being" pushed.

The way to...

The problem more likely is in the ballscrew assembly. It could be the ballscrew itself, the bolts that mount the ballscrew to the table, or the thrust bearing pack closest to the axis motor. .005"...
