Post by mtnkyr on Ethercat Master ^{CODESYS Forge talk (Post)}
Hi everyone, I am working on a 3 axes Cartesian robot. I take control of all the axes. In the Ethercat connection, the drive sequence is the same as in the program. For example, in the current program the order is as follows. 1. Axis_Z 2. Axis_X 3. Axis_Y Communication Diagram PLC->Drive_Z->Drive_X->Drive_Y When I try to change the order in the program while keeping the communication diagram the same, there is an axis drive mismatch. How can I fix this?

Post by kenth1973 on MC_Phasing state explenation ^{CODESYS Forge talk (Post)}
My MC_Phasing FB was stuck in iPhasingState=1 and error output HIGH on one axis. I could manually overwrite the state to 0 in the instance data. During normal run I see the state change from 0 to 10 to 100 back to 0 (maybe more states that I couldnt catch with the naked eye) But - what are the states numbers and their different explenations? This is not explained in the FB guide on codesys. (the pictures show state = 0 after I reset)

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

Hello, is there a possibility to change modbus server parameters (baud rate, parity, etc.) configured in devices tree from PRG? I need to be able to change them, for example, from HMI.

Post by taqamert on IFM-Sensor ADC READ ^{CODESYS Forge talk (Post)}
I have a pressure sensor that measures 0-600 bar and outputs a 0-5V signal, but my PLC reads analog inputs in the 0-10V range and displays a value of 1024 when 10V is applied. In this case, when the sensor outputs 5V at 600 bar, the PLC shows a value of 512. My working range is 0-350 bar, which means the PLC only uses 298 bits in this range, significantly reducing the resolution. What can I do to achieve better resolution within the 0-350 bar range?

Post by yofi on Raspberry PI change tag only responds after stopping PLC ^{CODESYS Forge talk (Post)}
Using V19 Patch 7 and 4.11.0.0 for Pi 4 Model B, My problem is whenever I change a tag e.g bool from true to false it will change in software but the pin will only go high to low after pressing stop PLC in codesys and same if i want to bring it back to high, have to login start plc change it and stop plc in order to change. any insight ? 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 trusty-squire on Confused by dwIpoTime input for SMC_Interpolator ^{CODESYS Forge talk (Post)}
Hi, Learning Codesys CNC, and I am confused by the dwIpoTime parameter. I have a basic demo application, using SMC_Interpolator feeding into SMC_TRAFO_Gantry2Tool2, which then sets the position of the x/y SM_Drive_Virtual axis. I also have a C axis which revolves the tool, which is controlled using a simple tangential angle calculation SMC_CalcDirectionFromVector. The GCode I'm using has feed/accel set at 500. The axis configuration limits are well above that (2000). What's strange is that, when I run the simulation, the feed speed changes drastically when I update the variable dwIpoTime. The larger the number, the faster it moves. What's going on here? The documentation only says "This variable has to be set for each call. It represents the cycle time in μsec." Why does it change the feed speed I'm seeing the in simulation? What is a good number to use? The example I was looking at set it at 5000. Screenshot attached.

Post by mubeta on Strange problem with the ‘MC_SetPosition’ function ^{CODESYS Forge talk (Post)}
CoDeSys 3.5.19.7 Target Berghof MX6 In a simple SoftMotion programme with two stepperless modular axes from CMZ, one is simply controlled in speed, but a spot must perform a positioning. I use the function MC_SetPosition() both to reference the axis at power-up and also to correct the actual position to a fixed machine reference detected with proximity. The function has only one instance and I actually use a booelan variable to control the ‘Execute’ input. Well, I cannot correctly change the axis position on the fly if it is running at high speed. The servomotor works in a speed range between 0°/s and 720°/s, (gearbox output with a 1:6 ratio). As long as the servomotor is operating at speeds below about 400 °/s, the function is able to correct the position correctly even when forcing values far apart, but at high speeds, from 400 °/s upwards, the correction no longer takes place. For example, trying to correct the position of 280° into 300° with absolute mode, the axis that is moving at speed actually shifts the position by a few degrees, not the expected 20. I don't understand why with the servo drive running slowly the position shift occurs correctly, while increasing in speed it no longer works.

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
