Hello PLUS +1 Community,

I am completely new to this controller and CAN.
I am trying to control an electric motor using Plus +1 and Danfoss e-Wheel, I have MC024-120 controller.
I want to read CAN messages from e-Wheel and after some logic send an Analogue signal which will control the electric motor.
The firs issue is CAN messages from e-Wheel, as for example it is U16 signal for steering position, where values 0-4095 contains information of the steering position and 4096-65535 means no information. But when i read messages of specified Bytes using CAN explorer, it fluctuates a lot from 0 to 65000. It gives the correct values also but it fluctuates to point 0 and 65000.
I don't understand what to do now. I am attaching a screenshot here, in that the Red line is steering position, which gives correct value for most of the time stamps but then you can see it just fluctuates. Same happens with Velocity signal. As per e-Wheel catalogue, it sends message in 50ms, so i have same as Log Period in Service tool. Even if is limit the output it does not solve the problem as there will be an output corresponding to maximum the messages of 65000 value should be excluded completely, but also there is 0 which is not correct value but is there. I tried decoding the bits and only taking 12 bits, but of course it does not solve the issue.

I will be hugely grateful if anyone can help me here. Ultimately I need analogue signals to control an electric drive.

Thanks in advance.

There is lots of ways to bake the NV cake, best read the help file to determine which 1 suits your application.

Select the function block in the component library
"Non-Volatile Memory Dynamic" or "Non-Volatile Memory Dynamic with Default" in particular
They are found in Component > Connections > Non-Volatile Memory Dynamic

Once component is selected press your F1 key on the board, this will pop up help file and the examples on how to use can be found in there, look in the menu on left, Example 1, 2 and 3 etc.

Hello.

I have a DP610 display in an old snow cat for a ski resort here where the screen it self is just white on bootup, all the buttons work and apparently the manufacturer does not have these displays or anything to replace it.

I'm wondering if anyone knows what TFTs these displays use or if anyone has encountered this issue and figured out a solution? My guess is the TFT itself is gone bad (although it might as well be the TFT driver or ribbon cables etc)

The display uses J1939 to read information from a Cummins diesel engine and the hydraulic system (ran by old MC510 controlers).

The ski resort is ran by volunteers so I'm doing this pro bono just to help them out. Any information or help appreciated.

I am getting this on a project after updating to 2024 version
*** ERROR 587 *** [PLUS1_IDE] INTERNAL: Unexpectedly reached else in {TXmifPresenter.GenerateOutput}
Same project was working fine in 2023 version. What is wrong?

Hello I am new to Danfoss! THANK YOU FOR ANY HELP!!

I am trying to control a proportional valve with a PWM signal, the valve requires a 0 to 600mA.

What are the steps involve in this. as simple as possible?

1. Scaling. the valve is inversely proportional so 0mA= 3000PSI and 600mA=0PSI, I can use y=mx+b or scale function from library.
2. is there a function block needed to output a PWM? or can I send the scaled value to the Multifunctional Output?
3. how is the ping configuration done? Output mode option 3,4 or 5?

Thank you again !!
