What to Do: Check
4 Traversing pro-
grams Traversing programs are needed only for the “Automatic” mode and are not
necessary for the startup described here. Generally, it is not needed until you
start up the user program on the S7-400 CPU.
5 Create SDB
w

000
When you have completed all start-up actions on the FM 453 and your plant,
create, save and load SDB
w
1 000 into the CPU/onto the memory card of the
CPU. All the parameter data (DBs) of the FM 453 (all 3 channels) are stored in
SDB
w
1 000. This SDB allows you to replace the FM 453 module in the
event of a fault, and to download the parameters without a programming de-
vice/PC.
Note
The measurement system (MD7) must match the measurement system speci-
fied in the other DBs.
The measurement system raster (MSR) is the smallest distance unit in the
active system of measurement.
If at some point you have failed to take this precaution:
1. Delete all data blocks of the relevant channel (which do not match the
measurement system) or clear the memory of the FM 453 completely.
2. Modify the other data blocks on the programming device.
3. Reload the data blocks to the FM 453.
The table below shows you what initial contents are recommended or re-
quired for the E machine data at startup of the machine axis.
Enter the machine data in the tab windows in accordance with the control
mode (MD61) as shown in the following table.

1) This pair of values corresponds in the case of servomotors to the speed category of the drive. It serves as a basis for
calculating the K

factor in the servo, and must therefore be entered correctly.
Recommendation: So far as possible, U

should be set in the range between 8 and 9 V.
