hello, Currently I am making one project from one packaging machine and have one doubt. I have one encoder as master axis and one servo to make some movements I want to move servo for example 55degres between encoder positions. start position example 60º and end position 180º What type of cam do you recomend? Do you have any videos with similar aplication. I have the same type of movement on Omrom Sysmac but in codesys I am having some problems making it work correctly. Thanks in advance for your feedback.

to naswer this question deeper understanding of application is needed. technically you always have poly5 between two points. you can manipulate start and end velocity to make it stright line if needed.......If videos here can not help you then you should check with Codesys and their training program. Master encoder is no different from basic principal to a servo drive. difference is that you will probably have to apply dead time compensation + filters in case encoder is low resolution and give problems like vibartions.....keep in mind that applying filters is also introducin lower accuracy.... I hope you will be able to run the machine. unfortuantely i can not help you. unfortunatel "something is not working corectly" is statement too wide to provide any concrete solution to your issue.....

@@SoftMotion-Black I understand that is difficult to help without knowing machine details. currently on my project I have one encoder as master axis and 2 servos One servo controls one belt conveyor and I need to input how many milimeters the servo must move, but syncronized with master If I increase from 40mm to 65mm the servo will need to run faster to make the movement between 60º degrees from master. But if I increase degrees from master for example 100º with the same 65mm it will move slower to because it has more 40º from master to make the same movement. In Sysmac studio it is much simpler to make this cam function.

still it is hard to understand this application based on your description. nevertheless, first you need to have same units in master/slave configuration. use mm for master and slave scaling. in this way you will be able to clearly understand the relation. unfortunatly i have no experience with symqc studio so i can not compare. unfortunately i can not help you.

Thanks for this intro lesson. I am using a raspberry pi 400 and a Control Techniques Digitax drive - it works well 👍👍

I tested these functions, they work fine until the PLC power is turned off. After the PLC and servo are turned on again, the gear settings return to the old settings. Do you know how to change these values permanently? For example, in Mitsubishi's Simply Motion, you have to call the "WriteFlash" function. All changes to the electronic gear, soft limits, etc. are saved permanently. Is there such an option in CodeSys? P.S. The videos are made very professionally and to the point. Without unnecessary talk. They are a pleasure to watch. Best regards.

Hi. Thanks for feedback. initial gear ratio is going to be always the one set by axis editor. so, technically you can store last settings to persistent retain variables and after power cycle write them again using FB. keep in mind that raspberry plc does not have NV memory dedicated for such variable type so it will not work on this hardware platform. other manufacturers of dedicated PLC hardware have this option. second option which would work is to save settings to a file (on raspberry file would be stored on sd card) which you read out on power on. i hope i helped.....

Thank you for such a quick response. I solved the problem exactly as you suggested. I save the gear variables in Persistent Retain and after restarting the PLC I initialize the gears. I thought that since the axis editor can save the gear data permanently, it can also be done from the program level. It simplifies the program, you don't have to initialize the driver. That's what I do in the Mitsubishi controller. Ok, now I know that Codesys and PLCopen don't have a similar tool. Best regards. P.S. I'm going to watch more of your videos. :-)

Coud you please make a video of 2 dimensional array? I need to use it for a program where I have to control de velocity of the knife during the cicle wich will depende from the parameter of the cutting distance.

hi. videos were made aprox. 4 years ago and I (re)upload them because of interest. new videos are curently not palned. i dedicated my time for other things (family primarily) and I do not se how this will chnage in near futur. however, try it yourself. 2-dim. array of CAM points is not so different from 1-dim array so this video should help you alot.....for futher assistance you should contact codesys support.

Hello, can I use this Read and Write SDO even if I dont have any EtherCat slave device repository... or I need to install the xml file to be able to use this option

@SoftMotion-Black 3 ай бұрын

you need a device to be at lest in pre-op....so yes....you need a device which is imported by xml. i am not sure how this can be possible in any other way....a least on ethercat. it is not a bad idea to create support ticket with all details directly to codesys....

Is set position here only for that purpose? On my first attempt I didnt use “set position” and errorID:34 showed up, when trying to use absolutemove not sure what it is but something is not quite working. Do you know what this might be? Could it be a license issue? Thanks Blackmotion guy.
