Note
The measurement system (MD7) must match the measurement system specified
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 (which do not match the measurement system) or clear
the memory of the FM 353 completely.
2. Modify the other data blocks on the PG.
3. Reload the data blocks to the FM 353.
Initial contents of MD
The table below shows you what initial contents are recommended or required for
the E machine data at startup of the machine axis.
Enter the machine data in the tab windows or in table format in accordance with
the following table.

FM 353 Stepper Drive Positioning Module

Tool offset data is needed only for the "Automatic" mode and is not nec-
essary for the startup described here. Generally, it is not needed until
you start up the user program on the S7-300 CPU.
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 S7-300 CPU.
When you have completed all start-up actions on the FM 353 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 353
are stored in SDB w 1 000. This SDB allows you to replace the FM 353
module in the event of a fault, and to download the parameters without
a programming device/PC.
FM 353 triggers no process interrupts
Specified reference-point coordinates
Software limit switches inactive
Reference-point shift (incremental encoders only) should be
entered for numerical readjustment of the reference point
