Example
Assumptions: Spindle configurations:
Specifying the spindle number and machine axis
MD35000 $MA_SPIND_ASSIGN_TO_MACHAX [AX4] = 1
MD35000 $MA_SPIND_ASSIGN_TO_MACHAX [AX5] = 2
MD35000 $MA_SPIND_ASSIGN_TO_MACHAX [AX6] = 3
MD35000 $MA_SPIND_ASSIGN_TO_MACHAX [AX7] = 5
Applying a machine axis in the channel
MD20070 $MC_AXCONF_MACHAX_USED[0] = 4
MD20070 $MC_AXCONF_MACHAX_USED[1] = 5
MD20070 $MC_AXCONF_MACHAX_USED[2] = 6
MD20070 $MC_AXCONF_MACHAX_USED[3] = 7
Specifying the master spindle
MD20090 $MC_SPIND_DEF_MASTER_SPIND = 1
Spindle number converter
MD20092 $MC_SPIND_ASSIGN_TAB_ENABLE = 1
Activate spindle number converter
SD42800 $SC_SPIND_ASSIGN_TAB[0] = 1
Master spindle as configured
