Tool-, spindle- and machine commands (T,S,M)
3.3 Parameters of "T,S,M"
Input mask for tool-, spindle- and machine commands:
Values can be entered directly in the orange marked input fields or by se-
lecting predefined parameters with the "SELECT"-key.
Alternatively the "INSERT"-button in the selected cursor field opens a se-
lect menu of all possible parameters, in which you can navigate with the
"Tab"- key as well as the blue "cursor-up"- and "cursor-down"-down but-
tons. The button "INPUT" takes over the selected values.
In order to be independent of country specific measuring units [metric/
imperial] not all units are displayed in the input masks.
See module B518 - "Basic operations".
In this documentation the measuring units are always metric.
