Machine data
S MD13050: DRIVE_LOGIC_ADDRESS[n] (I/O address of the drive)
tells the NCK the I/O addresses of the drives defined in the S7 project using
”HW Config”.
The machine data index (n+1) is the logical drive number for the NCK.
2
The machine data
S MD30110: MODULE_NR[0] (setpoint assignment)
S MD30220: ENC_MODULE_NR[0] (actual–value assignment)
are used to assign each individual machine axis to a drive.
The logical drive number m to be entered in the two machine data refers to the
entry with the index n=(m–1) in the list described under Point 1 MD13050:
DRIVE_LOGIC_ADDRESS[n].
3
Machine data
S MD20070: AXCONF_MACHAX_USED[n] (machine axis number valid in
channel)
defines explicitly which channel axis and which machine axis is used and de-
fines implicitly how many channel axes exist in the channel.
The machine axis number m to be entered in the machine data (with m=1,2,3...)
is referred to the appropriate machine axis m.
4
Machine data
S MD20050: AXCONF_GEOAX_ASSIGN_TAB[n] (assignment geometry axis –
channel axis) (n = 0...2)
defines explicitly which channel axis is a geometry axis and defines implicitly
how many geometry axes exist in the channel.
The channel axis number k to be entered in the machine data (k=1,2,3...) is
referred to the entry with the index n (n=(k–1)=0,1,2...) in the list of the channel
axes MD20070: AXCONFIG_MACHAX_USED[n] (see Point 3).
