6.9.15 Spindle encoder matching
The machine data for matching the spindle encoder is the same as for the axis.
For spindles, it is always MD 30300: IS_ROT_AX and MD 30310:
ROT_IS_MODULO that should be set so that the encoder matching relates to
one revolution. To always view the display in relation to 360 degrees, set
MD 30320: DISPLAY_IS_MODULO as well. If the motor encoder of the 611D is
used for the encoder matching, then the matching must be entered for each
gear step if there are several gear steps present. The maximum multiple of the
611D drive is always used as the maximum multiple of encoder markings. This
multiple is 2048.

Note
These MD are not required to match the encoder, but they must be entered
correctly for the sake of setpoint calculation. The load revolutions are entered in
MD 31050: DRIVE_AX_RATIO_DENOM and the motor revolutions in
MD 31060: DRIVE_AX_RATIO_NUMERA.
