How can the servo roll forward the entire day without any limit?

Hi sir.

I have a question about this example

https://support.industry.siemens.com/cs/br/pt/view/38391227/en

It is a Motion Control program, but it has a programmable "superior" limit and a "inferior" limit. I want the servo roll forward the entire day without any limit. By the way, i want to control the frequency of the PWM output in order to control the speed. is this possible?

Which versions hardware and software do you have?

BR

The "Pulse" instruction is V1.0 on Tia portal V14 SP1

The "Motion Control" instruction can be 6.0 if i want to.

By the way, i can use CTRL_PTO but if the "motion control" works, i will chose it.

Please do not base your choice on looking at the version numbers. That only indicates the evolution of the internal code. If the code is done right, no further version number increase is needed.

I understand you wish to do speed control. In the configuration of the axis, there is a place to set the hardware and software limits. You can choose to switch that option off. Them you can use speed control instruction block or (my recommendation) use the jog function instruction block.

The speed control reacts to edge trigger commands while jog reacts continuously.

thanks for your answer. 

i found a place where i can deactivate the "software limit" option. Tomorror i will try it.

By the way, how can i manague the PWM frequency? i mean, there is a limit of 200Kbps on the signal board, and i want to try 2.000 bps, 10.000bps and so on, using the example of this post.
