FM 353 Stepper Drive Positioning Module

Checklist
Despite the “acceptance” testing just mentioned, the ultimate responsibility for the
accuracy of all machine data lies with the module user. So it is highly advisable to
perform startup using the following checklist.

Machine data
Set initial machine data contents
As shown in Table 5-4 machine data are subdivided into configuration
data (
K
) and setting data (
E
). K data indicates how the FM 353 is con-
nected to the machine axis or CPU user program, and must therefore
already be fully set up before startup begins. When specifying the
MD13 (number of increments per motor revolution) for drives with ad-
justable increment number, select the one with which your maximum
frequency (at maximum axis speed provided) reaches the next lowest
value below the FM 353’s maximum frequency of 200 kHz.
E data is intended for changes during startup, and serves to optimize
FM 353 response for the technological process of positioning.
The values in Table 7-3 are recommended, and sometimes necessary,
as initial settings.
Initial machine data assignments for FM STEPDRIVE
To help you start up your machine axis with FM STEPDRIVE and the
SIMOSTEP motors, you will find the MD DBs for open-loop control
mode in the directory
[STEP7 directory]EXAMPLES\FM353\MD
:

SIMOSTEP 2
si02_353.md

SIMOSTEP 4
si04_353.md

Increments
Increments are only needed for the “Relative incremental” mode. For
the next part of the startup procedure it is helpful to set up an “Incre-
ments” data block (DB-SM) with the following values:
Value 1
1 MSR
Value 2
10 MSR
Value 3
100 MSR
Value 4 1,000 MSR
Value 5 10,000 MSR
with rotary axes:
Value 6 1 rotary-axis cycle (MSR) MSR = measurement-system grid
