That is a machine fault.You need to look at the machine manual for that or ask the machine manufacturer.

Hi, i have problem with machine cms sinumerik 810M (M6T), year 1984
what happend is that i cant get 0 point, cant move by any axe or move it manualy by hands... and i cant reset alarm that i got on screen
7024 - AXES DRIVING GEARS NOT READY (72-73)
thanks
That is a machine fault.You need to look at the machine manual for that or ask the machine manufacturer.
If you drive in Emco-Sinumerik the error code tell us:
7024: ADJUST CLAMPING DEVICE PROXIMITY SWITCH !
When the clamping device is open and the position stop control is active, the respective proximity switch has to feed back that the
clamping device is "Open".
Check and adjust the clamping device proximity switch, check the cables.
But you have a cms if I've got it right. In Sinumerik 810M/-94 are no such high numbers.
So although I think gridley51 right but others might benefit from this Code
system maybe working slow
I'm also in the process of starting up a CNC machine ( Triax PF 4t) with a sinumerik 810 M controll. Have removed all errors and if I do hit Emergency button and resett to clear the alarm the Servodrives enables and we can feel the servo is holding. I hear some beeping from the servos. I don't know if this is a alarm or just noise from the servo. But after a few seconds I got the alarm 7024 Axes driving gears not ready. What does this mean. My alarm list does stop at 7023 so not much help in that. could it be something with the Brake on the Z aksis
7024 is a plc alarm.
What I don`t know is what it means on your machine.On mine it means "incorrect tool selected",so obviously it is machine tool builder specified.
If you can find a file called PCA in your control,it should be readable with notepad.
Do you have any suggestions how I can find this PCA file?
I understand that this is the machine builder that should know this but seems to only have controll of the messages up to 7023. I Belive that it is a signal that goes into the I/O board. I have tried to find anything there but haven't found it jet. Is it possible to see the logic signals that error 7023 is dependent of. If I found that it would be possible to find where the source of the error is. Probably it is a faulty wire or something. the machine has not been inn operation and have beed moved since it was used. But backup battery is OK and all mecanical parts seems to be OK

The message comes from the plc as do all 7000 number messages.
You are correct that all signals go in and out the i/o board this is why it is called that.
The plc is issueing this message because it is either not seeing an input or an input it can see is is not going low when it should.
Do you have electrical drawings for this machine?
As said already this message can mean different things on different machines.Only someone with the same machine or the machine builder can tell you what the message means.It is not easy to troubleshoot a Siemens controlled machine remotely you need to do the work.
For example,what type of servodrives do you have?
Are they ok and outputting a ready/healthy signal to the control?
Do you know how to run the drives independently of the control?
Do not assume because the machine worked at one time that it is still working,you have stated that you have cleared errors,what errors?
Do you know how to connect a computer to the 810 and download the operating parameters and the plc programme?If so have you taken a backup of the control settings?This is how you will find the PCA file.
What version of 810M is it?
Thanks for fast answers
I don't have any PLC dokumentation files
The error comes when I try to move Z axis to reference point. I have tried to just jog the Z aksis and it moves a little and then the 7024 alarm comes and everything stops. It is possible to do reference search and jogging on the X and Y axis.
I disconected the Z axis ( only mecanicaly) to check that the brake worked. Because there is a brake on the Z axis servo. When the power is off the brake is on. When I turn the machine on and press Reset to clear the alarm then the brake go of and I could easily turn the servo with my fingers??? I belived the servo should be stiff controlled by the Drive?
Yes I have electrical drawings of the machine But I can't find the input that gives me this problem.
The Servodrives is Simovert Siemens (Se image for the label of the simovert)
I believe I could run the drives independent of the control with a +-10V signal but I have not done that jet.
Yes I have connected the controll to the Computer and downloaded everything I was able to download. But I did not find a way to download PLC program. Do you know how to do that? ( I have attached the files I downloaded from the controller ( Except the main part programs and sub programs Because that's maybe not so interesting.
The Verison of the 810 I belive is possible to see from the lable on the controller
Sinumerik 810 M

Now you are coming with some useful information.
It sounds as though everything is ok until you jog the Z axis.After you have jogged the axis and the control has errored out,with the power still on,check for 24vdc at terminals 72 and 73 on the Siemens axis drive.The terminal number may be 72.3 or 73.2 but it doesn`t matter at this stage.
If you find you only have 24vdc at one of these terminals,power down and power up and check again before jogging the axis.
This is the drive ready/healthy signal.
To download the PLC data and see the %PCA file you must do an "Overall reset"
You can read about this in the Siemens manual 346_810 GA1 Interface Pt1.
Be very careful unloading data if you are not sure what you are doing as if you lose it you are in deep trouble.
To talk to these controls you need the Siemens Step5 programme and PCIN.
If you cannot find a copy of this on the Siemens website PM me an email address and I will send you a copy.
The reason I asked what version of 810 you have is that there are three releases of this software.They are GA1,GA2 and GA3.
"It sounds as though everything is ok until you jog the Z axis.After you have jogged the axis and the control has errored out,with the power still on"
Yes this is rigth. And when the error comes the servoes dissables. I did not measure terminal 72 and 73. But I had the belt cover off the x axis and the servo was holding until the error of the Z axis come.
the reason I start to belive that Z axis was the problem was becaus a red diode on the z axis drive card was on after error. (See picture)
How do I find if my version is GA1 GA2 or GA3
