There is a very simple explanation for the symptom you are describing. The load meter and all of the LEDs in the electrical cabinet use power from the low volt power supply in the electrical...

I have seen the pressure adjustment valves for the tailstock and chuck make a noise like the one you described. You can see if the noise changes pitch when the pressure is adjusted. Most Haas...

I believe the amp would function okay on another axis. I'm just concerned that whatever caused the other amp to fail may also damage the A-axis amp if it is swapped. The motors should be tested for...

Hello Murphdog,

I do believe that your machine has a bad Vector Drive. The alarms that you mentioned are related to the DC buss voltage from the Vector Drive. These alarms are indicating that...

Alarm 140 Y motor Z fault indicates that the machine is getting an unreliable Z marker pulse from the Y servo motor encoder.
As others have mentioned, the first thing you want to do is re-seat the...

There are a few things that can cause this type of problem, such as a faulty contactor or spindle drive. Other things can be looked at, such as the counter balance system. The alarm description can...

Hello Vulcan,

You said that you only need to align the turret in X. This sounds as though the turret is neither mechanically too high or too low; it is simply not positioning correctly for your...

A Haas certified technician can access the spindle and servo hours in the control. This is not normally accessible to the operator. And yes, these hours can be reset if a processor pcb has been...

What is the symptom? Is the shuttle stopping in the middle of travel? Is the machine generating alarms during tool changes? Is it getting turret rotate faults, or shuttle faults?
One other item...

Hello,

I believe that someone gave you some good advise by telling you to check the power supply. The low volt power supply distributes both +12 and -12 volts. Both of these need to be checked. ...

I will explain this as best I can. When the machine is "zeroed", the axes travel to home switches and then back away from the switches to a specified offset. This grid offset becomes the zero point...

Have you checked the condition of the motor mounts? They are made of rubber, sandwiched between two rails of steel. When they wear, the motor sags. I've seen this problem many times before. One...

I don't know what the noise you are hearing is coming from, but I do know that the Toolroom Lathes do normally make sounds which are different from the other SL series machines when the spindle is...

The hydraulic turret is now standard equipment on the SL-30s and 40s. You will need to confirm whether your turret is hydraulic or pneumatic. The hydraulic turret's A-axis motor is keyed and is...

Mark,
Both controls are great. I think the biggest difference in the Haas control is that you have most everything right in front of you on the keypad, whereas the Fadal uses menus and other...

A quick way to rule out the A axis drive, is to swap it with another drive in the electrical cabinet. If you suddenly get X or Z drive faults after the swap, the amp may have a problem. If it...

I was looking at your levelling procedure and I did not see any adjustments made to the level after jogging the Z axis and seeing the twist.

If you are seeing a twist or roll along the Z axis,...
