Комрад, как в параметрах с обратной резцедержки на обычную переключиться ?
Comrad, how do you switch from reverse tool hold to normal in the parameters?

Is there a way to reset the plc only without deleting my nc data?

Just do the procedure with the S4 switch (2-3-2) and leave S3 on 0. Should work. Described in the Siemens Manuals. Be sure you have created and stored current backups before.
