Link axis

Assumption
NCU1 and NCU2 have one link axis each,
machine data e.g.:
; Machine data for NCU1:
$MN_NCU_LINKNO = 1 ; Set NCU number to 1
; (Master NCU)
$MN_MM_NCU_LINK_MASK = 1 ; Set link function to active
$MN_MM_SERVO_FIFO_SIZE = 3 ; Size of data buffer
; between interpolation
; and position control
$MN_MM_LINK_NUM_OF_MODULES = 2 ; Number of link modules
$MN_AXCONF_LOGIC_MACHAX_TAB[0] = "AX1"
$MN_AXCONF_LOGIC_MACHAX_TAB[1] = "AX2"
$MN_AXCONF_LOGIC_MACHAX_TAB[2] = "NC2_AX3" ; Link axis
; Unique NCU axis names
$MN_AXCONF_MACHAX_NAME_TAB[0] = "NC1_A1"
$MN_AXCONF_MACHAX_NAME_TAB[1] = "NC1_A2"
$MN_AXCONF_MACHAX_NAME_TAB[2] = "NC1_A3"
CHANDATA(1)
$MC_AXCONF_MACHAX_USED[0] = 1
$MC_AXCONF_MACHAX_USED[1] = 2
$MC_AXCONF_MACHAX_USED[2] = 3
...
; Machine data for NCU2:
$MN_NCU_LINKNO = 2 ; Set NCU number to 2 (slave NCU)
$MN_MM_NCU_LINK_MASK = 1
$MN_MM_SERVO_FIFO_SIZE = 3 ;
$MN_MM_LINK_NUM_OF_MODULES = 2
