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

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

CODESYS Forge

(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 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.

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.

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.

Post by abuckie on Getting raw value as full resolution for ADS1115
CODESYS Forge

(Post)
I just found this and I am getting a value larger than 16 bit, around 81000 something. I am reading a 5 volt value and I am using level shifters for the i2c bus. This is how I have the channel configured: ADS1115.usiAddress := 16#48; ADS1115.ChannelConfigs[0].Active := TRUE; ADS1115.ChannelConfigs[0].PGA := FSR_6144mV; ADS1115.ChannelConfigs[0].InputMux := Single_0; RawAnalogValue := ADS1115.Channels[0].Value; It looks like every value is a multiple of 3. Any idea where to look to fix this? I think i found what I want to change in UpdateChannels Channels[FChannelNo].Value := INT_TO_REAL(WORD_TO_INT(LValue) * GetFullScaleRange(ChannelConfigs[FChannelNo].PGA)) / 2048.0; I try to edit it but I can't, sorry if this is a basic question, I am new to CODESYS.

Post by konstantin on Lenze i950 Servo and WAGO PFC200
CODESYS Forge
talk
(Post)
Hello, In our workshop we have a Lenze i950 servo drive that has an EtherCAT bus and CiA402 compatibility. The WAGO is PFC200 750-8212 and as per documentation it has built-in license for SoftMotion Light functionality. It is not capable of supporting the full SoftMotion functionality like gearing and synchronizing. I added the EtherCAT esi files from Lenze and the EtherCAT master does see the drive, then I added a SoftMotion Light Axis object. The problem is that I can only energize the axis, I cannot execute any other commands. I set the positive and negative torque limits from the PDOs to 200% and when I try to move the axis by force it does not move back to its original position. I use the SML function blocks from the PLCOpen library and the error from the function blocks is that the op mode cannot be changed. Then I tried using a standard SoftMotion axis object and everything works fine, except the MC_Home function block. The axis moves back to its position when forced out of it. I follow this guide from Lenze - Lenze i950 CODESYS V3 What could cause this issue with the SoftMotion Light axis object? Best Regards Konstantin Kolev
