And i have some problems Fist: What command should I use? -Currently i am using the command "MoveVelocity" in motion control. But I can't let the velocity change continuously. Can this command change the speed continuously but only need to execute it once.? -I hope you can guide me to do this project. Thank you very much.

For me, it sounds like Motion Control with technology object, am I right? If so, which hardware (PLC, drive, …) and which TIA Portal version are used? Kind regards Stefan

But I can't let the velocity change continuously. Use MoveVelocity to start the axis with maximum velocity you require. For changing speed use yourAxis.Override.Velocity. Hint: axis can be started even if velocity override is 0.

So you end up thinking that the number is the representation. - Andrej Bauer Any claims against me - based on whatever legal reason - resulting from the use of any code and/or ideas presented on this forum shall be excluded. #StayWithUkraine

Assuming you are using the S7-1200. + Use the "MC_MoveJog" instruction instead. + Get yourself the manual: SIMATIC STEP 7 S7-1200 Motion Control V6.0 to V7.0 in TIA Portal V16
