In general, drives have parameter sets to adjust behaviour in such cases: position recovery, adaptation with resistant torque, out-of-position window failure, etc. (Much depends on the type of configuration set for the axis: positioner, speed controller, torque controller, etc.). I have used that type of drive very little, in only two cases and a long time ago. To tell you what is normal is impossible. I know by reputation they are very simple objects, without too many pretensions and adjustments possible. Try running traces by monitoring actual position, motor current, torque and following error. These are the most sensible curves to understand what is going on. Maybe by fine tuning the motor tuning, the current controller or the speed controller you will get something closer to what you want. For example, from DS, the motor has a standstill torque of 3 Nm. Observe with traces whether this is effective: motor current trend. And afterwards, when you have your own accurate picture of the situation, you can also hear from the product's local support to see if you can steal a few more things from it performance-wise.

Hello, when I download AlarmManager.project from https://forge.codesys.com/prj/codesys-example/alarm-manager/home/Home/, it gives an error when I open it. If I ignore the warning and continue to open, the alarms are missing. ** Exception Text ** System.ArgumentNullException: Value cannot be null.

CODESYS Forge

(Post)
I am trying to implement a Ladder Logic (LD) function block in CoDeSys that increments a value A by B every T time interval. My Structured Text (ST) version works perfectly in simulation, but when I implement it in LD, it does not work. The ST code: PROGRAM ADDITION VAR_INPUT A : LREAL ; B : LREAL ; T : TIME ; END_VAR VAR Timer : TON ; END_VAR Timer (IN:=TRUE, PT := T); IF Timer.Q THEN A := A + B ; Timer(IN := FALSE ) ; END_IF;

Hi yotaro, hope your problem was resolved. I had the same, but with an other library title. This exception is not detected during compilation, but rather at a given position in the program (when switching to a given visualization). Although the exception is generated at this point, it does not involve the visualization in question. This error is due to one of 3 reasons: 1) A division by zero somewhere: The program is able to detect divisions by zero at compile time. But in the case of a variable, which takes a valid value at init and changes to 0 at a later stage. 2) An invalid pointer: (either because it has a value of 0, or because it points outside the memory reserved for the program) is being dereferenced. Locate any pointers or interfaces you have in the code and check them - you should also be wary of mixing inline modifications and pointers. 3) Array overflow: Generally when a processing operation is executed outside the array's definition range. Example: a write loop with n iterations is executed on an array of dimmension n-1. On the other hand, the error message may not appear. In the latter case, the error may have fatal consequences, as the overflow has induced writing to potentially forbidden memory areas. This problem can be explained by the fact that it's not always the adjacent memory areas of PLC_PRG that are overwritten, but the memory areas that are randomly allocated to the array during compilation. In this case, however, there is no entry in the log, so you need to integrate the "Implicit Check function", which checks the line of code generating the error. To integrate this functions, click on Application --> POU for implicit controls Regards,

i need help creating a digital clock in CODESYS that should be displyed on a Raspberry Pi LCD Display trough the Visualization built in CODESYS. I have an idea how to display the time by making a 7 Segment Dysplay in the Visu. But I don't know how to get the actual time into the program. Can anyone help?

I had similar issues with the OnDialogClosed not being called. I realized that this behaviour is resolved, when the according visualization object on which the input configuration is set is moved to the foreground. Somehow, the object has to be one of the lowest elements in the Element List (i.e. in the foreground) for it to work.

To search for an exact phrase, put it in quotes. Example: "getting started docs"
To exclude a word or phrase, put a dash in front of it. Example: docs -help
To search on specific fields, use these field names instead of a general text search. You can group with AND or OR.
