Sabre 750 Acramatic 2100 Error
A couple of months ago I had a random error when booting up. I shut down and restarted it, and problem went away. Then a few weeks later, same issue, but it took about 3 or 4 restarts to clear.. Last time I started it, same thing, but about 6 or 7 restarts. Here is the error display:
Attachment 423402
READS:
Cause: See Cause (2)
Cause (1): The spindle enable signal (M1SPDL_ENBL) is not on, but the spindle drive ready (M1SPDL_READY) signal is on. It should not be on at this time.
Cause (2): The spindle enable signal (M1SPDL_ENBL) has been set on, but the spindle drive ready signal (M1SPDL_READY) has not been received.
All I can tell from this is that either the spindle drive is not producing the proper ready signal when it should, or whatever is supposed to receive that signal is not successfully receiving/recognizing it. Beyond that, I can't tell anything else from this. I just don't have enough understanding of the system to go much farther.
FWIW: The spindle drive was rebuilt in June 2017. If it has 200 hours on it since then, I would be surprised.
Having owned this machine for many years, I know how this goes. The issue starts infrequently, then continues to get worse until one day it just won't start. I don't run it every day, usually only 2 or maybe 3 times a month at most, so I would like to preemptively fix this if I can.
There are some real experts on this control on here, sure hope one of you knows the problem. You have been very helpful in the past, and I have always returned the favor by spending my money with you for repairs.

Check relays cr 24 and 25 if they get 24v, and if they close circuit.

Can you give me any details about the function of these relays? Is one or both supposed to be turned on by the Spindle Drive Ready signal?
Re: Sabre 750 Acramatic 2100 Error
Yes, both should turn on by spindle drive. Dallas chip maybe going faulty.

Why the jump to suspect the RTC? What do the two have to do with each other?
I replaced the WS battery in 2012, but the RT had no battery, it only had this device:
Benchmarq Real-Time Clock Module #BQ3287MT
I am assuming this is what you are referring to as the Dallas chip. If the RT battery was dying wouldn't the clock be losing time?
BTW: There is this thread from 2012 where I review my procedure for changing the battery. I also discuss the RT module. This old thread is the only way I still had a record of the exact module on the board.

UPDATE:
I have not gone dark on this thread, but the 2 times I ran the machine since my original post I have not had any issues. Can't do much troubleshooting when the problem runs and hides. I will update if it comes back. I did locate the 2 mentioned relays and poke and prod them a bit, so it is not out of the question that action did something if there is a connection issue happening there.
In the meantime, if someone can explain what the Benchmarq Module mentioned in post #5 does, I would be interested to know. Does it have a battery/finite lifespan that needs to be a point of concern?

So after about 1.5 years, this problem reappeared today.
Machine has been running no problems, then at the end of a tool change, the spindle braking did not work. Instead I got the below "Spindle Stop" error, and the spindle coasted to a stop after several minutes.

I shut down and restarted everything, and the spindle timed out without running. This time it gave me the same Spindle Drive Not Ready as in my first post here.

Next, I shut it down again, restarted, this time it worked testing through MDI. So I restarted program, it successfully indexed and changed a tool, ran that one tool, and worked fine until shutdown before tool change. Then it gave the same Spindle Stop error as before. A new restart and it won't even index the spindle to do a tool change.
Going with the previous suggestions, I checked relays C24 & C25. C24 is off and open, C25 is on and closed. So if the previous information was correct and both must be on, then whatever controls C24 is the likely issue. But this puts me back at the same issue I always have when this machine gives problems. I am very good at electro-mechanical troubleshooting, but without more documentation, troubleshooting this is nearly impossible.
If anyone can help here, I am dead in the water.

In sabre electric are pictures of wiring diagram.
Hope it helps.

I will download these, they look potentially helpful. Thank you.
Re: Sabre 750 Acramatic 2100 Error
It is the VFS5.
Where can I find that software? Sounds like a must-have if I am going to keep trying to use this machine. People with parts and knowledge on these are quickly disappearing. I have an older laptop with a serial cable I can use it for this job.
So what exactly does CR24 do? Is it carrying a fault condition from the RT to the drive, or is it carrying the fault form the drive to the RT?
Also, I kept tinkering last night for several hours trying to trace the issue. One thing I did was to just touch the cable to the top molex plug going into the back of the drive, and when I did, several relays did all kinds of clicking and switching. When I went around to the machine, I had a new code for an encoder issue. I did not take a picture of it unfortunately, but when I completely recycled the machine, it ran with no problems for about 2 more hours last night. So today I am taking my electrical stuff to the shop and take a close look at all the contacts in this plug. I don't know what all is contained in this plug connection, but I assume that a bad contact here could be causing all of this. Is there some form of Spindle Ready input contained in this cable?
