Hi all.
I have cinncinati Hawk 150 with acramatic a2100, vickers drives.
On startup it passes all diagnostics, then waits for the green button to power up hydraulics and servos.
Once I press it, hydraulic pump start, vickers drivers for x and z start, 3 Led's turn green.

X axis servo motor rapids down excessively, causing machine to shake, and errors X axis servo fail, X axis servo error.
Can anyone suggest me where to start?

Has this machine been running and no changes have been made??? Do you get an open loop error?? Have any wires or motors been changed?? Give us more history.

I purchased it not long ago. We had a problem with booting windows nt. A Real time motherboard got detached from main board and was throwing errors upon diagnostics. That's sorted now. No other errors apart from that: errors 44-45 X axis servo fail, 44-44 X axis servo error. I took some pictures of cables and servo drive jumper settings.

Any Suggestions?

Tom i have the same machine and had some weird issues over the years but not this one.Do you get a chance to home the machine or does this happen when just pushing the green button to activa the e the system.I would check to see if your limit switch are stuck or damaged because these axises can be moved before the homing process has been completed and if they have been over run in the past they may have been damaged.The only otherthing i can think of is may be a relay or a switch thats stuck on the x axis curcuit.I hope this gives you a start to get it sorted because when running there an ausome little machine.cheers greg.

Hi.
https://youtu.be/LHZdl66I66c

Limit switches are good.*
Can I swap servo drives from z to x just to eliminate x servo drive error? They are slightly different , on x is bds4 206 23 412w32 and on z *bds4 210 23 414w25.
"may be a relay or a switch thats stuck on the x axis curcuit" -*don't know where to look for one.
If I had optical scale on x, would it cause it to rapid?
Thank you
Tom

That's not a rapid at all. That's the drive thinking it's ready, and the x axis brake releasing.

Hi. I dont think brake release would cause machine to shake, also there's about 400V on servo drive output.

If you have proper voltage, not that just having voltage is always correct, the motor windings may be failed. It certainly looks like typical axis drop from the amp or motor not holding torque.

Would you advise to get another servo drive?

Hi. I swapped the servo drive from z to x and it's still doing the same thing. Measured the resistance on the motor, then thru cables, it shows around 5ohm between phases. Same as z axis.
What am I missing here.

The motor wires are phase sensitive (6 poles), make sure the 3 wires at the drive are in the correct position.

Hi. Thank you for your reply. There's Ma Mb and Mc on the drive, cable has writing on 1,2,3. So a1, bo,c3.
I swapped the drives and it's still happening. So the problem has to be between drive and motor itself.
I disconnected motor power (3 fases) and it did an axis drop but slower, like brake release and then alarmed.

Now as it hits lower limit switch it goes up and errors overload.

Hi guys.
I'm still struggling. I bought another vickers bds4 drive, and still same thing happened. So I have one bds4 for sale.
This machine was equipped with linear scale, but that's disconnected before I bought it. I did some backup restore, Maybe I need to change some parameters, in case the backup for x axis included linear scale being on?
But how would you do it?

I cannot tell from ur video anything. Too little data. If indeed x motor runs away then that may be caused by missing or bad scale. Is there a scale? If not, fives can send u a doc how to change to drive enc emulation output.

Sounds like ur drive, motor, motor cables are all good (or it would not have reversed dir and gone up again after ls). Prob most likely in bad or missing scale.

Hi Mike. Correct. The scale was unplugged and wires in bd4 "closed loop", but it still had scale feedback in axis setup. We change that to motor feedback and hurray no more jumps.
There's another issue, as soon as I start spindle, it " crashes " with SPINDLE OT ERR.

I found a guy locally who knows Cincinnati, hopefully he can sort it out.
Thanks

U hve Mach diagrams? We brought ot vfs5 thermostat out of drive and back in an io point... special. Is that maybe not the original vfs5? Got full part no?

I finally solved this problem, no more spindle over temp on hawk 150.
It was a broken wire from r37 socket, that's thermistor from spindle motor.

Over the past year the battery for WS board failed, causing the bios to return to default settings.
And that caused booting problem.

https://youtu.be/ZYnPEAYThnE
WS board failed light was red on extension board BBB.
I read somewhere that acramatic a2100 needs to have proper bios settings.
So I messed with it and it starts now ok.
Here for future reference bios settings that work for me

One more thing to get it running. In mdi G97s100m3 works fine, and I can go to s3000 fine in 100 increments.
But the machine doesn't like to accelerate from 0 to 500 or more.

We think it's something around the spindle motor, there no ohms between 2 black cables. On my mill spindle motor shows 160 ohms.

hi could you send me pics of motor feedback axis setup ,please

or someone who can tell me what parameters it should have for motor feedback, please

thanks
