11.5.20 Spindle basic data
The spindle mode of a machine axis is a subset of the general axis functionality.
For this reason, the machine data required to commission 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 MD30300: IS_ROT_AX (rotary axis/spindle)
S MD30310: ROT_IS_MODULO (modulo conversion for rotary axis/spindle)
S MD30320: 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 MD35000: SPIND_ASSIGN_TO_MACHAX (spindle number)
The spindle number must be unambiguous within the channel axes of the c han-
nel 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 Section 11.5.1, Page 11-310).
The diagram below illustrates the spindle modes and possible transitions be-
tween them.
