7.1 611A main spindle drive machine data (MSD MD) (SW 3)

7.1.1 MSD MD input (SW 3)

The main spindle drive machine data are provided for the purpose of matching the main
spindle drives and the machine tool. If no setting values are specified by the machine
manufacturer or the user, then they must be carefully determined and optimized by the start-
up engineer. The setting values are input by means of menu selection (see section headed
"Machine Data Dialog").

7.1.2 MSD MD (data description - SW 3)
