Optimize The Spindle; Set The Machine Data For The Spindle - Siemens SINUMERIK 828D Commissioning Manual

6.5

Optimize the spindle

6.5.1

Set the machine data for the spindle

Checking the machine data settings
Match the machine data default settings as well as all relevant parameters for spindle/axis
interpolation with the machine data in the following table. The example is true for a spindle
motor without mechanical gearbox stages with 8000 rpm.
The machine data can be initialized with the suggested values shown in the table. The values
vary depending on the application.
