New release 2.1.0.107 crashes while motor tuning

[kandauru]

Hi,

I was trying to tune motors in new release of Power PMAC Suite, but when I pressed "Do a Step Move" in position loop interactive tuning window, the software crashed

and restarted itself. The small note: the motors are in gantry - follower mode.

Please, advise.

I just tried a simple test of gantry follower with motors 2 following 1:

Motor[2].ServoCtrl = 8

Motor[2].CmdMotor = 1

 

I was able to step motor 1 without issue. Can you provide details on your motor setup and firmware version? This may be better handled a technical support issue contact us at support@deltatau.com with the details.

We believe this is a firmware related issue. We have just released a new version that will correct this – it is on the Forum's FileDepot.

yes, it looks like the problem was in firmware. After I have downloaded the new one and installed it, the software is working.

Thanks!

A new problem - homing is not working( I recompiled the project, downloaded it to controller many times). See my homing routine in the attached file. It looks like MOTOR[X].HOMECOMPLETE flag stopped becoming signaled.

 

Please, advise.

I have checked this function with the latest released IDE and firmware and it works correctly. It might be the case that your PLC has very slight timing differences that cause you to miss the flag.

 

Try checking the HomeComplete flag using a simple on-line home command.

I am having the same issue where the IDE (2.1.0.107) crashes when I attempt to do a open step response.

 

Primary option: I know that i can do an update to my firmware to fix this, however right now I'm stuck at 1.5.8 since when I upgrade any higher, my code doesn't run correctly at it did before. So I always had to revert back

 

Backup option: I believe that I was able to do the tuning fine with my old IDE (version 1.6.0.109) however, when I go to download filedepot to download it, the file is only about 9 mb in size. Where is it supposed to be ~700 mb in size. Is there a way I can get access to this old version of the IDE?

 

thanks,

windell

This file appears to have been corrupted. I will post a correct version shortly.

Hello Steve,

 

I have found the problem with homing procedure (look at line 46 in my attached file sub_home.pmc):

 

there is an expression:

 

gatenumber = int((inMtrNr-1)/4)

 

in case when inMtrNr = 4 or 6, the result is wrong - 1 and 2 accordingly (should be 0 and 1).

Please, check it.

What was the previous version of firmware?

This has been reposted with a non-corrupt version.

Thanks Steve!

I've attempted to start the tuning process with the old IDE (1.6.9) and I'm getting the same behavior that the IDE crashes when I try to do a step. I'm in the process of upgrading my firmware, but there are some unexpected hurdles that I need to leap over before that happens flawlessly.

 

Any suggestions I should try? I've tried tuning using the newest IDE and 1.6.9 and both do the same thing.

The previous firmware version was - 2.0.2.14

 

We are going to re-release the firmware (as 2.1.1.0) with the correction to the "int" function on 4-10-16. It will be placed on the FileDepot.

Not sure if you meant 10th May with this. We need the 2.1.x.x firmware pretty sharpish, but obviously can't release with the broken int function. Any news?

[steve.milici]

Sorry I did mean "May", I will have it on the FileDepot location this afternoon.
