Information on programming the Sequence Controller
The sequence controller AST6 is already pre-configured in its delivery status.
A functioning screw assembly program is already available for the enclosed EC
screwdriver. The screw assembly programs and settings must however be adjusted to the
present application case.
Default settings and parameter changes of the screw assembly programs can be done
directly on the sequence controller AST6, refer to
Operating via the Touch Display
.
The web interface must be used to modify or create new screw assembly programs refer
to
Operation via the Web Interface
. The default programs screwing at torque, screwing at
an angle of tilt and loosening at angle of tilt, can be created and parametrized at the
sequence controller AST6.

Functioning of the Sequence Controller AST6
The screwdriver is controlled via the I/O interface. If an optional fieldbus module is
installed, control may be done via the fieldbus module or via the I/O interface. The choice
is made in the menu.
Applying the start signal initiates the screwing in operation. The program specified via the
program selection is started.
After switching on the sequence controller AST6 the main screen will appear.
Figure 4: Main Screen: Process Display
The number and name of the active program is displayed on the upper line.
In the second line the date, time and duration of the last screwing application is displayed.
In the status area the last screwing application is displayed. The status field will be green if
the screwing application was fault-free. The status field will be red if the screwing
application was ended with a fault. In this case a help text is shown that indicates the fault
description. To display this text tab on the input field with the fault message.
The results of the previous screw fixing operation are displayed for the step, moment and
angle. The field for moment is red if the previous screw fixing operation was terminated
with a torque error.
