15.9 Spindle data
Introduction
The spindle mode of a machine axis is a subset of the general axis functionality. For this
reason, the machine data required to start up an axis have also to be set for a spindle.
The machine data to parameterize a spindle are therefore to be found under the axis-specific
machine data (from MD 35000 onwards).
Note
After the default machine data have been loaded, no spindle is defined.
Spindle definition
With the following machine data, a machine axis is declared to be an endlessly rotating
rotary axis whose programming and display is carried out modulo 360 degrees.
• MD30300: IS_ROT_AX (rotary axis/spindle)
• MD30310: ROT_IS_MODULO (modulo conversion for rotary axis/spindle)
• MD30320: DISPLAY_IS_MODULO (modulo 360 degrees display for rotary axis/spindle)
The machine axis is converted to a spindle by defining the spindle number x (with x = 1, 2,
...max. number of channel axes) in machine data
• MD35000: SPIND_ASSIGN_TO_MACHAX (spindle number)
The spindle number must be unique within the channel axes of the channel to which the
spindle is assigned.

Spindle modes
The spindle can have the following modes:
• Control mode
• Oscillation mode
• Positioning mode
• Synchronous mode synchronous spindle (S3)
