Function Library / PID function block weirdness?
« Last post by G30RG3 on July 30, 2021, 06:48:01 PM »
Hi all,

I've got a stability issue with a PID speed control.
I'm trying to use a PI or PID Function block, v4.0 and Ive got some weird behavior:
When I disable the I- and D-functionality by setting the gains at 0, The I still rises when I change a speed set-point from 0.
By using the I-stop I'm able to cut that.  So the I-output and D-Output stay at 0, which is what I want.

But then I've got a next issue: Setting P-gain incrementally higher, results in my application getting stable up-to about 50% of the set-point, further increasing the P-gain, the control (P-Output) starts to oscillate wildly, without the error ever going negative. I would expect an oscillation to start once the Feedback goes over the setpoint, but I'm seeing this way before the first peak-value reaches set-point.

Any Ideas why the P-output behaves so weird?  I don't think there is an issue with overflows on my end of the programming, but a lot of the FB is hidden...

Telematics / Configurations sometimes not all showing up on PLUS1 CONNECT
« Last post by FluidPowerTom on July 28, 2021, 08:32:27 PM »
Title says it all.  I thought I was crazy the first time it happened or that I'd accidentally deleted my latest Configuration version, but now it's happening again.  Then some days later when I logged in the version I thought had disappeared was back. 

This morning I was able to see all of the several versions of this Configuration I made, and for some reason right now I can only see a few of them.

EDIT:  What I've learned is that some of the configuration versions only show up in the Danfoss default group.  Why would only versions 4, 5, and 7 show up in the customer's subgroup but all versions up through 8 show up in the default group?  I could be mistaken, but I think they were all made in the subgroup.
Telematics / PLUS1 CONNECT J1939 Signal Library
« Last post by FluidPowerTom on July 27, 2021, 11:30:24 PM »
It looks like the SPN's from DM01 are not in the J1939 library as I go through the fairly exhaustive list of signals that are in there.  I guess there must be a reason for this, but I don't know what it is.  Is there a reason?
Telematics / Reports on PLUS1 CONNECT

There is an issue that the 'Reports' area on the left side of the portal is only visible when you're connected to the Danfoss Default Group.  As a result of this basically customers cannot set up reports.  This needs to be fixed soon.

I do keep my files up to date via update center.  The issue was this was a program that has been in place for several years. I don't update old programs when new hardware files are released.  Too many programs out there to do this unless it's required.  In this particular case I needed to update 11 programs.

Was there a PIB that covered this issue?

Hi FluidPowerTom,

That was my expectation as well. But since it's vacation time i can't get any information on this subject.
I hope it will be revealed what is happening next week.

Have a nice day

Hi FluidPowerTom,

Missed one then.
The last month,or two, there have been a radical increase of "spam" accounts trying to get access. Sometimes one gets through the net.
I will remove his post, and account.

Thanks for letting us know.
