PPNC downloads and executes the NC file, and executes the first file to make it run normally, the running time is 45 minutes. After modifying, downloading and executing the NC file parameters again, the NC execution line has not completed the current line, but jumped to the next line for execution (two lines of code were executed at the same time), which caused an accident.
In the attachment, G01 Z [#301] F0.5 is running, and the trajectory has not been completed. The speed is not the specified speed. G04 X1 has been activated. The trouble is that these two codes run at the same time.
When the NC file does not complete the current line and enters the next line for execution, there is another problem with the axis speed setting, which is not what I expected. The motor is in the trajectory I specified, has accelerated to a speed (much greater than the specified F), and then started to decelerate to 0 and completed the trajectory at the same time.
I asked all possible questions, but no results. I hope I can get help in the DT community. Due to this problem, the device has stopped functioning.

Jeff, thanks for your reply.
I don't know much about gpascii communication, I just started to learn to use Power Pmac. Can you provide some information for my study and reference?
Thanks very much for your help.

By writing C language, using the "Command" command to read a configuration file, build and download it. I passed the query command, but the parameter was not assigned correctly.
Command("system gpascii -2 -i/win/MYSETUP.txt");
Is this statement wrong? Or is there an introduction document for the API function Command/system gpascii.
I need to customize some functions, and I hope the administrator can send me some documents about these introductions.
"WRITING C FUNCTIONS AND PROGRAMS IN POWER PMAC" is just an introduction, there is no introduction of functions and commands.

HI, Geoff, I have some doubts about the settings;
First of all, the index of the EncTable you defined is 10; but the index of the EncTable selected by your motor is 6? Can this match?
Secondly, the data of your motor feedback comes from ECAT's IO data, I guess this is sensor data.
Geoff, if it is convenient, attach the complete plan to facilitate our study.
EncTable[10].type = 11
// Source register address: Motor control output register (FP)
EncTable[10].pEnc = Motor[1].IqCmd.a
// Data shifting operation: 5 = left shift this many bits (32 - bits of actual data)
// Command output pointer
Motor[1].pDac=Sys.pushm
// Outer (position) loop position feedback pointer
Motor[1].pEnc=EncTable[6].a
// Inner (velocity) loop position feedback pointer
Motor[1].pEnc2=EncTable[6].a
Motor[1].pAbsPos=ECAT[0].IO[4102].Data.a

I believe that is referring to an internal part of the development of the NC SDK. You can probably take it to mean the NC SDK.
Eric you are right, I think this is part of the SDK.
Because the SDK is not completely open at the moment, I see this MCF Developer's Guide 2.3.pdf document and feel that I can do HMI to solve the problems I am currently facing. This is just my thought.
If the NC team does not help, this problem is indeed difficult to solve. I believe that other customers will encounter the same problem.
Well this is actually an array issue and not an issue at all once you understand the system. The edits to make this work are on the ppmac side not the HMI side. The file ncinterfacedefinitions.pmh is where the edits take place then all will be write with the world.
The axis order has everything to do with how the edits take place. I have run into this many times and very easy to correct.
Thank you, I have to re-recognize Power pmac nc, I first try to modify the plc program to achieve the functions I need.

Our G54 implementation does not include the C axis. If you wanted to add that functionality yourself, I believe our code is open enough it would be possible, but not easy.
I know the code that runs on PMAC much better than I know our NC HMI. When you run a G54 that will run on PMAC and here is the standard implementation.
// G54 set work coordinate system 1 n54000: dwell 0 // Stop lookahead and blending ThisCs = Ldata.Coord // Coordinate system executing program XworkOfs = CS1WorkG54X YworkOfs = CS1WorkG54Y ZworkOfs = CS1WorkG54Z //Cancelling Locals XlocOfs = 0 YlocOfs = 0 ZlocOfs = 0 GCodesGroup0 &== ~Group0_G52 gosub 50000 // G50 disable scaling gosub 50100 // G50.1 disable mirroring gosub 69000 // G69 disable rotation MacroGCodesGroup14 = 54 GCodesGroup14 == Group14_G54 return
You would need to declare and set C versions of the variables that exist for X/Y/Z and set them in this code. Then you would have to search for where in the project the X/Y/Z variables are used and do the same thing for C.
That is in addition to editing the code you're looking at to include the C axis. If you want to make those changes I can ask the CNC team your questions.
I asked how the C axis was used because there might be an easier way to do the same thing.
Eric ，thanks very much.
Sorry for interrupting you to rest; I can solve this problem by myself. You can help me to consult the CNC team, how to get "MCF Application for Delta Tau (CS).zip". It is mentioned in MCF Developer's Guide 2.3.pdf. I can develop this function myself.
Eric, thanks again.

I have a feeling this might go deeper than you thought and require editing the G-Code library saved in the controller, as well as the front end for the NC display.
What is the C axis used for?
Eric, I'm sorry to tell you that even if the code of G54 is modified, the data entered manually in workoffset. C cannot be set. The terminal correctly displays the data of P903.
When I was debugging the program, I inserted a breakpoint in "btnCsSetALL", P900 had the correct "DisplayName", but P903 did not display my C-axis coordinate values. The code in WorkOffsets.xaml.cs has been executed correctly, but the variable is not assigned. What is the reason? At the same time, I found that the code of "Machine.cs" is also running correctly. ""{0}-axis work offset for {1}"" has been loaded successfully.
In the MCF framework, P903 is not assigned, and P900-P902 are assigned correctly?
If this is the problem, please re-write the assignment code to the variable that I cannot assign, and send me the correct .dll file (I have no permission to modify the MCF framework).

Eric, thanks for your reply.
I use the ck3E in the simulation, this should be the B axis.
I will modify it according to what you said, or please tell me to modify the g-xx code (should not be all?).
-
In the process of machining, the position of tool tip should be written into G54.
The first problem is that when you press the workoffsets button and then the all button, only X, Y, Z coordinates are written into G54. even if the C button is pressed, the position of C will not be displayed in G54. C;
Second, of course, the C coordinates of the tool tip can be manually written into G54.C. then, when the NC program is running, C does not participate in the calculation and does not work.
Is this a bug? If so, this error is too low-level.
I want to know how to get the coordinates of G54 X Y Z C, and at the same time, it works when running NC program.I have purchased the SDK. You can provide the setup document for me to modify.

Can you provide a full screenshot of the PMAC NC Software? Particularly the Positions and the sections below that, showing (amongst other things) the G- and M-Codes that may be active at the time where it stops.
Do you have the Power PMAC IDE installed? If so, it may additionally be worth checking the value for Coord[x].ErrorStatus (most likely Coord[1].ErrorStatus if you are unsure), along with looking at the "Global", "Coordinate System", and even "Motor" tabs of the Status Window to see if any specific errors are showing up on one of the relevant pages for your system.
Thank you, AAnikstein. You are right. It is coord [x]. Errorstatus that causes this problem. Where can I query the information of PPNC alarm information?
-
Where are you getting this error message? I'm not used to seeing it from the Power PMAC NC Software. Are you able to post a screen shot of it?
Does it seem as though it's a particular line of code? If you have the ability to do a "dry run" or run on a virtual machine, can you comment out sections of the code and see if it is being caused by a particular line? If you comment out sections of the G Code starting at the end and working forwards, can you narrow in on a specific section that is causing the problem?
thanks,AAnikstein.
When the NC program runs to line 9, an error is reported.

When power PMAC NC runs NC program, an error "interference move calculation time" is reported? Which document has a detailed introduction?

Is there a reason you are setting it up in IDE 3/EC Engineer, generating an eni file, and importing it into IDE 4? In IDE 4, you can do all of that (EC Engineer has been incorporated into the IDE).
Please try making it entirely in IDE 4. To do this, either make a new project using the "PowerPMAC with EtherCAT (Acontis)" template or by right clicking the "EtherCAT" folder under System in the Solution Explorer and add an EtherCAT Master. After that, if you click on the Master, many of the screens should be the same as they were in EC Engineer, though if you go to the "PowerPMAC IDE Manual" under the Help menu, it can guide you through it.
Once everything is finished and configured, I would issue "$$$***" to the PMAC via the terminal, then right click on the master and select "Load Mappings to Power PMAC", then perform a project Build and Download, issue "save", and an "$$$". After that, I would try to enable EtherCAT again and see what happens.
OK,THANKS

Did you add the ESI files for your ecat modules to the IDE?
If you go to the "EtherCAT" menu, you will find the "ESI Manager" where you should be able to browse to a file location.
What did you do before the error occurred? It would be much easier to diagnose if I knew when it happened. Was this after scanning the network?
Eric，Appears after scanning the network. Through the help system of IDE, I found the reason for the error.
0x9811002E
EC_E_MASTERCORE_INACCESSIBLE
Master core not accessible
RAS
Connection to remote server was terminated or master instance has been stopped on remote side.
But I don't understand, where is the root of the mistake?
Through the EC engineer of IED V3, I can successfully communicate with the IO module. At this time, I export ei.xml. However, when I import ei.xml into IDE V4 that I am using, ECAT [0] cannot be activated. There are no errors and warnings. Enter $$$* * *, save, as always.

Today, I loaded three ECAT I / O modules. The EC engineer pop-up dialog box prompts:
error: Master core not accessible(error code：0x9811002E )
I want to know why this error code appears? Is there a problem with my XML file?

I also reorder the power PMAC CPU.
I don't think that was necessary. The RMA wasn't either.
I want to upgrade the CPU firmware. Can you tell me the way to upgrade and send the latest firmware to my email?To get a firmware update, you should email your local support channel, possibly your distributor or OEZ. That being said, your firmware is pretty up to date, I don't think firmware version is the problem.
I think you just need a little help setting up your phasing. I will try to address this in the other thread.
Eric, thank you so much for your reply.
I have applied for Omron to repair 24e3 of power pmac. How long is the repair cycle?
-
The values of PhaseFindingDac and PhaseFindingTime are quite low and likely will not lead to reliable phasing. This process has to have the motor and if enough time and current are not provided it can give random results. Motor[x].AbsPhasePosOffset=1877 could be a check that the motor has moved far enough, but that value might not be set up correctly.
It also sounds like you want to be doing halls phasing. I would suggest taking a look at the Brushless Motor Phasing section starting on page 134 of the PowerBrick LV manual available here.
http://forums.deltatau.com/filedepot/download.php?f=Power%20PMAC/Manuals/Hardware%20Reference%20Manual/Power%20Brick%20LV%20User%20Manual.pdf [FILE REMOVED]
This manual is not exactly the same as your hardware, you will need to change PowerBrick to Gate3. It is just a useful manual to go through the whole setup process because it is a manual for an all in one form factor. It will show you how to either set up Halls Phasing with correction or an automatic method that moves the motor depending on what you prefer.
motor [x]. CountError = 1I think you mean Gate3.Chan[j].CountError, but set it equal to 0 in a startup PLC.
For these types of questions you should really reach out to your local support channel. If that doesn't work I'm happy to help, I don't want to leave anyone with a PMAC stranded, but please start with them.
Thanks for your reply

Sorry I was mistakenly thinking we were talking about the environmental temperature like Alex. If a component on the 24E3 itself is 70 C I would not be worried.
At present, the problem is that after restarting power PMAC, the Open-loop test direction changes and cannot operate normally. I'm worried that the problem of 24E3 caused the reverse of Open-loop test.This is likely unpredictable phasing. What are the values of the following variables?
Motor[x].I2tSet
Motor[x].PhaseFindingDac
Motor[x].PhaseFindingTime
Motor[x].AbsPhasePosOffset
Motor[x].PhaseFindingDac=200
Motor[x].PhaseFindingTime=10
Motor[x].AbsPhasePosOffset=1877

ARM LS1021a would be the CPU type not the firmware version.
To see your firmware version enter "vers" into the terminal. It should be 4 numbers like 2.5.2.0. This is also visible near the top of the screen on new enough IDE versions.
Each firmware version is compiled for each CPU type (ex Dual Core ARM, PowerPC 460, PowerPC 465). Whether the CPU has EtherCAT or not is irrelevant to what firmware version is installed.
My firmware version is 2.5.1.7
The machine tool adopts linear motor movement. After ppmac looks for the motor phase, the Open-loop test is passed. Restart at power PMAC, input at terminal
#1 $, do the Open-loop test again, and the Open-loop test result will reverse.
This problem has been going on for a long time.
I checked 120 ° - hall feedback, gate3 [0]. Chan [0]. UVW is correct. This problem still occurs when searching motor phase in multiple positions. Acc24e3 temperature is very high, axle card has been applied for repair.
I can't get rid of the Open-loop test problem, which is caused by CPU. I also reorder the power PMAC CPU.
I want to upgrade the CPU firmware. Can you tell me the way to upgrade and send the latest firmware to my email?

The firmware version of power CPU with EtherCAT communication is ARM LS1021a？
What is the firmware of POWER PMAC CPU version without EtherCAt communication？

Is it normal for the temperature of 24E3 to exceed 70 ℃?
No, this is not normal.
The ambient temperature is 18-22 ℃, and the temperature of 24E3 is above 70 ℃ after one hour of startup and operation.The 24E3 should come with a fan meant to be placed just underneath. Is it installed?
Is the 24E3 in a cabinet? Does the cabinet have a fan?
Thanks for your reply.
The electric cabinet has fans. The temperature of other components is normal, including my driver. The power module of power PMAC has a fan, which has been installed correctly, and the CPU temperature is stable at 23-25 ℃. Through reasonable layout of components, the cooling fan of the driver can also cool the power PMAC.
-
If the ambient temperature for the CPU is over 70C, it must be lowered by adding more/better ventilation or cooling.
The CPU is rated for an ambient temperature of 0-45C.
If the motor is reversing directions, your phasing may not be strong enough.
Try phasing the motor at multiple locations and verify that it succeeds at all of them.
The ACC-24E3 axis card exists in both a standard (16384 counts/cycle) version and a version with an optional Autocorrecting Interpolator (ACI), which results in 65,536 counts per revolution. If you have the ACI, then yes, 65,536 is correct. Regardless of which version you have, your UMAC Rack needs a lower ambient temperature.
There is another problem: After Power PMAC is started motor [x]. CountError = 1;
24E3 P/N 3-4002A6262-4646-B00 S/N P907081
At present, the problem is that after restarting power PMAC, the Open-loop test direction changes and cannot operate normally. I'm worried that the problem of 24E3 caused the reverse of Open-loop test.
The ambient temperature is 18-22 ℃, and the temperature of 24E3 is above 70 ℃ after one hour of startup and operation. For debugging, I have searched for phases in multiple locations, and I have determined that the wiring of hall is shielded.
Is it normal for the temperature of 24E3 to exceed 70 ℃? This is what I need to confirm
If I can't solve this problem, I can only apply to Omron for repair.
PPnc executes NC file normally for the first time, and becomes abnormal when executed
in Power PMAC-NC16

Eric, thank you for your reply. [#301]-Through the monitoring window of the IDE, the assignment of the P variable is correct. [#301] represents the stroke of the Z axis. In the currently executed NC machining program, the value will not change with the cycle.
Even so, the motion program executed 2 lines of motion at the same time.
I am looking for errors caused by sys or coordinate system variable assignment errors, or improper set values. However, I can't find any hints of the error.
please help me .thanks.
