You have an X axis cable problem. When E stop pressed power to servos are cut off. Buy a new cable end to end. Had the same issue with a larger Haas ST40 2013 machine. Intermittent several times per month and a real pain because you got to power off and re-home which a nightmare when using servo tailstock because it want to drop the work lol.
@@kinzy_fabrications You found it in the end is the main thing. Someone had me putting ferrites on the ends of cables and all sorts with mine which seemingly worked for a few weeks but it would ultimately fail. 👍
I replaced the bearings is a servo motor couple of years ago and some how changes the phasing of the magnets so it ran the other direction. Had to set the direction para in the control from 0 to 1 and that fixed it.
I have not tried that as yet, the motor jogs etc as normal but yes sometimes when it alarms with x servo error too large it does go in the opposite direction so il give it a go
HAAS needs an AI repair assistant like Grok, midjourney, chatGPT, etc. But it would diminish their new sales and maybe, bottom line by enabling Used machine users, and avoidance of repair centers.
Yeah, there's already lots of good info out there on the old machines but also a lot of scare stories on how they cant be fixed and you cant get parts etc, as i've always said, i would love newer machines myself but they are just out of my price range so these older ones can still be a great buy and earn you money
It turns out that you have a problem with the parameters. Do not change the board because it is technically unlikely. Check the axis and PID settings for the X axis, compare with another machine or, best of all, temporarily upload the settings from another machine.
So this morning i already tried that, loaded the parameters from a running machine with no issues to this machine but still same issue, so its now pointing me back to motor or cable which is the first thing i swapped
any changes by leaving it sitting for ~15min with the breaker off? Vector drive capacitor powering down over time can cause some weirdness. Yeah, but probable board or amplifier related if switching connections makes it follow the switch. what about swapping motor connections?
Makes no difference I also swapped the Mocon board, amplifier, servo motor and cables but still got the same issue so doesn’t not appear to be related to any of those
I had a servo error before. Turned out it was the fuse inside one of the amp drive units. Hardware store and $7 later fixed my problem. Hope that helps
Some online blog says this is an encoder problem. Can you dissassemble the ball-screw servo and clean the encoder? I have never taken the servo apart, and I don't know if it comes apart. Just my guess.
I have tried a spare servo motor, cables, amplifier and mocon boards and still have the same issue This one is a real headache to solve lol or I’ve missed something really obvious
Try changing out the main cpu chip on the main processor board if you have one that is compatible on a working board. the problem is not on the mocon board and cannot be the drive or drive cable because it is disconnected and you are still getting the error. The only time it is clearing is with the estop in on startup. Good luck!!!!
The cabling from the encoder has not been swapped. The error is stating a delay, which may be caused by excess capacitance through the connection. A corroded wire can be a cause. Good luck 🍀
That was my first point of call but even with a spare motor and spare servo motor cable I still get the same issue Also if I plug y axis motor cable into x axis mocon connector the issue moves to the y axis But I have changed mocon boards as well and still same issue Someone suggested try another processor board so il do that next
The issue seems to follow the X table. You’ve swapped motors, cabling and plugs. It points me to X axis stiction, first movement at cold start. Anyway, watch what the issue follows, it will point you on way of troubleshooting.
Most likely you have a damaged cable or encoder in the X motor. Do not disconnect the plugs because Mocon will give an error. Mocon will never activate the axis if there is no closed loop Mocon - Encoder - Amplifier - Mocon You can check it easily. Reconnect the entire Y axis, i.e. the encoder and amplifier, to the X position. Disable the Y axis in the parameters and see if X will move the Y axis.
I did swap the x motor and cable for a spare known good one and I still got the same issue, I also tried 2 other mocon boards and 2 amplifiers but still same issue Oh and also tried another low volt power supply etc but same issue
@@kinzy_fabrications Do a test, turn off the X axis and connect the X motor and amplifier cable to the Y sockets and check if it starts. You will have a tested X axis motor and encoder.
Just had this it is a parameter setting I am out on holiday back tomorrow afternoon will look when I get back I will comment I did not find it John from northern machine tool in Chicago from it when I sent him all cards and he tested
If I plug y axis cable into x axis mocon plug I then get the error on y so the issue stays with the mocon board x connector But I have tried other mocon boards and still get the same issue so I will have to try processor board next and ribbon cables between boards
@@ducati543 the plugs on the right from servo amps to mocon I tried swapping over and tried disconnecting all together but still gives the same x phasing error
I have tried another motor but still get the same issue and even the same issue when motor and encoder are disconnected so it must be a processor issue maybe so I am going to try another processor board tomorrow

Ive tried spare motors but made no difference on this occasion
Have you tried reversing the X Axis direction? Cant remember the parameter but its a 1 or 0. I think the motor is traveling in the wrong direction.

Thanks, I have 3 or 4 other good processor boards spare so I will try that

Could be one of the pins are not tight enough. Giving you a low voltage to X
It gives the same error even when using other cables and boards
I'm thinking it's got to be on the input side. Not providing the correct voltage. Test your input cables.
I’ve tried different cables with no result
It’s the encoder cable
Turns out it was the motor/encoder, check out the latest video for the full explanation
The cabling from the encoder has not been swapped. The error is stating a delay, which may be caused by excess capacitance through the connection. A corroded wire can be a cause.

@kinzy_fabrications If you turn off the X axis in the parameters, do the Y and Z axes work?
@marcin5546
If I disable the x axis in parameters then I get no error on power up and the x and y axes home and work fine after a power up restart
@@kinzy_fabrications Do a test, turn off the X axis and connect the X motor and amplifier cable to the Y sockets and check if it starts. You will have a tested X axis motor and encoder.
Did you try a different motor or encoder ?
Yeah I had tried other motors and cables and also Mocon boards, servo amps and power supply’s

I will comment

Try switching the input from X into Y

But I have tried other mocon boards and still get the same issue so I will have to try processor board next and ribbon cables between boards
@kinzy_fabrications I'm talking Input not Out put. The plugs on the right side of the board. Not the ones you described in the video.

Not a Haas man, so I'm limited I can usually diagnose somethings with hands-on, but from across the pond, that's a hard swim at my age 😊.
Ja miałem ten sam problem, okazało się że pin się wykruszył we wtyce przy silniku.
Można sprawdzić miernikem od wtyczki A do wtyczki B czy jest napięcie. Mam zdjęcie które piny są użytkowe, było chyba ich 11
