Post by kleeswi on Visualization scaling problem with B&R T30 panel ^{CODESYS Forge talk (Post)}
I have found a work around. I have written a python scripts that runs on user login (entry in .bashrc) which overwrites the webvisu.htm and webvisu.cfg.json file with the configuration for the B&R T30 panel (resolution and disable scaling). First I tried to add this setting to the the CODESYSControl.cfg, but that does not work following the big CODESYS Control V3 Manual. [CmpTargetVisu] Application.WindowPositionX=0 Application.WindowPositionY=0 Application.WindowSizeWidth=800 Application.WindowSizeHeight=480

Post by charly29160 on WebVisu scaling regression in V3.5.22 P2: frame size jumps when switching visualizations ^{CODESYS Forge talk (Post)}
Environment: - CODESYS V3.5.22 Patch 2 - CODESYS Control for Raspberry Pi MC SL - WebVisu in browser Problem: When switching between visualizations using a Register element (Registerkarten), the displayed frame size jumps incorrectly after returning to a previously viewed visualization. This behavior was introduced in V3.5.22 Patch 2. The same project worked correctly in V3.5.21 Patch 4. WebVisu settings in V3.5.21 (working): - Scaling: Isotropisch - Automatisch ermittelte Clientgröße verwenden: active - All visualizations: Automatisch erkannte Visualisierungsgröße Workaround?

Post by sercan on Connecting Parameter 'A' in G-Code to Physical Axis in CNC Project ^{CODESYS Forge talk (Post)}
I want to run the following command by linking it to the A-Axis: G01 A45.0 Which TRAFO should I use to do this? SMC_TRAFO_5Axes and SMC_TRAFO_GantryCutter3 function blocks did not work! For example, when SMC_TRAFO_5Axes is used, parameters B and C can be resolved by the transformer. However, parameter A cannot be resolved. Only SMC_Interpolator displays the value of parameter A in the SMC_Interpolator => piSetPosition.dA output. Should I drive this axis with SoftMotion commands (MC_MoveAbsolute etc.)?

Post by spiessli on Softmotion axis to CANopen Maxon IDX drive ^{CODESYS Forge talk (Post)}
Hi, I want to use Maxon IDX drives for some simple robotic applications. I have used Maxon's Epos for generating a DCF file to import in Codesys (attached). Then I can add the IDX motors under a CANopen manager in the device tree. Unfortunately, I cannot add a "softmotion axis" to the IDX motors. Now I am wondering, why? Without being able to attach a softmotion axis to the device in the device tree, the use of the motor is greatly reduced... spiessli

Post by bertus on Axis directions in CNC editor not using right-hand rule? ^{CODESYS Forge talk (Post)}
Hello, Coming from robotics, I'm used to coordinate systems using the right-hand rule. But when I created below small NC program in the Codesys CNC editor, I noticed that the axis triad's Z-axis is flipped (see attached screenshot), resulting in left-hand rule. Is there a setting to change this? Or am I misunderstanding something in the CNC world? N000 G00 X0 Y0 N010 G01 X100 N020 G01 Y50 N030 G01 X0 N040 G01 Y0 N050 G01 Z25

Post by josepmariarams on Limit Axis CNC Jerk using SMC_Polynomial_AbsMaxLocs ^{CODESYS Forge talk (Post)}
Dears. Until now, I have been using CNC libraries with Codesys 3.5SP11. I was using SMC_Polynomial_AbsMaxLocs function, from CNC library, to calculate the axis jerks, interpolating splines, to limit it. Now I have passed to SP20, and the functions which calculates the zeros and the maximum-minimum and zeros of polynomials has been disapeared. Questions: -Exist any FB wich can limit the jerk of individual axis in CNC? -Exist any other functions which can calculate max-min and zeros of polynomials? Thanks

Hi, these variables are internal members of the axis. They measure the duration of some internal function calls.

Hi, you can take a look at https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_pragma_attribute_global_init_slot.html Maybe it helps.

You can simply excute the function block SMC3_ReinitDrive to the referred axis.

Post by poliautomacao on Absolute movement controlled by an external encoder. ^{CODESYS Forge talk (Post)}
Hello, I made this configuration, I'm moving the encoder value to SM_Driver_PosControl.in.wActPosition. When I make the absolute movement of my PosControl axis, my physical drive axis rotates perfectly, but I noticed that the movement is not followed by the encoder. That is, if I hold the encoder and keep it in position 0, the PosControl axis makes the absolute movement of 314 mm and stops, which is strange because the encoder is at 0. Theoretically, the PosControl axis should accelerate to try to compensate for the movement error. I haven't yet achieved perfect functionality.

Post by tk096 on gear over gear (2 masters,1 slave) - how to do it? ^{CODESYS Forge talk (Post)}
Hi, you could calculate the position/dynamics of the slave axis yourself and use one of the function blocks SMC_FollowPosition/SMC_FollowSetValues to move the slave axis. https://content.helpme-codesys.com/en/libs/SM3_Basic/Current/SM3_Basic/POUs/Movement/Direct/SMC_FollowPosition.html https://content.helpme-codesys.com/en/libs/SM3_Basic/Current/SM3_Basic/POUs/Movement/Direct/SMC_FollowSetValues.html

Just verified the behaviour. Still is the same. It should be attached here. But I also tried the DCF-file with the axis in the lab with the real drive: The MC_Power block never goes out of busy. Had not time to investigate further, though.

Post by florian on Stepper Drive with Ethercat ^{CODESYS Forge talk (Post)}
Codesys has a motion libraries (SoftMotion), but you need to buy a licence keys for them to work. the most basic one is SoftMotionLight. you just have to select your drive in the device view and add a SoftMotionLight CiA402 axis. then the library is added to your project. You can use the SML_* motion FBs and configure the axis now.
