Spindle definition
Spindle modes
10-362
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).
Notice
After the default machine data have been loaded, no spindle is defined.
By setting the machine data
S
MD 30300: IS_ROT_AX (rotary axis/spindle)
S
MD 30310: ROT_IS_MODULO (modulo conversion for rotary axis/spindle)
S
MD 30320: DISPLAY_IS_MODULO (modulo 360 degrees display for rotary
axis/spindle)
a machine axis is declared to be an endlessly rotating rotary axis whose pro-
gramming and display is carried out modulo 360 degrees.
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
S
MD 35000: SPIND_ASSIGN_TO_MACHAX (spindle number)
The spindle number must be unambiguous within the channel axes of the
channel to which the spindle is assigned, i.e. several spindles can be defined
with spindle number 1 provided they are assigned different channels (for
assigning machine axes to channels, please refer to Subsection 10.5.1,
page 10-308).
The diagram below illustrates the spindle modes and possible transitions
between them.
