Programming of cycles S3T

Hello everybody,

We have mostly “old” S3T controllers from Siemens in our firm.
I often have to mill things like width across flats and I’d like to write an own cycle therefore. But there’s no hint in our documentation about how it is to do.

The only thing I know is that I’ll have to work with the R parameter. But nothing else. I’ve looked up on the home page of Siemens but couldn’t find anything.

Could anyone help me? Maybe someone has a good documentation.

Thanks in advance!
