Starting up the FM 453
7.3.3
Basic Startup of Stepper Motor Actuation
Overview
The first step in the startup procedure for the drive is conducted to verify that
the stepper motor will traverse as a matter of course in response to actuation
by the FM 453 and therefore that the previously specified machine data are
set correctly. This step is particularly important when the drive is imple-
mented without an encoder, because undetectable positioning errors can re-
sult if increments are lost.
Use the following flow chart to verify the drive actuation and that the ma-
chine data determined so far are correct. A subsequent test should be con-
ducted to verify that the stepper motor will traverse as a matter of course in
response to actuation by the FM 453. A later test verifies that the positioning
is correct (see Section 7.3.8).
Note
Always be sure to put MD modifications into effect with "Activate machine
data."
Caution
!
Before triggering any traversing movement, be sure to check that there is
enough space for the axis to move in the desired direction.
