Note
For further information about spindle configuration, see above in this chapter in
the "Drive configuration" section.
For the purpose of matching the spindle encoder, the same machine data apply
as for the axis. MD 30300: IS_ROT_AX and MD 30310: IS_ROT_MODULO
must always be set for the spindle so that the encoder is always matched to one
revolution. IS_ROT_AX and MD 30310: ROT_IS_MODULO must always be set
for the spindle so that the encoder is always matched in relation to one
revolution. In order to obtain a display which is always referring to 360 degrees,
MD 30320: DISPLAY_IS_MODULO must be set. If the motor encoder of the
611D system is used for the purpose of encoder matching, then the encoder
matching data must be entered for each individual gear stage if several gear
stages are present. The maximum multiple of the 611D drive is always used as
the maximum multiple of encoder lines. This multiple is 2048.
