The sequence controller AST40 or ASTi40 is an integrated controller with power electronic. This screwdriving controller enables the individual adjustment of screwdriver torque, speed, waiting period and rotational direction. The sequence controller provides maximum flexibility for integration into existing processing environments with comprehensive operating options, programming and control functions, as well as documentation interfaces. The diverse communication options include input/output interfaces and various fieldbus interface options, as well as a touch screen and integrated web server for parameter adjustment, data backup and screwdriver graph analysis via Ethernet.

The screwdriving controller contains predefined basic programs for all standard screwdriving procedures. System commissioning is therefore accomplished in just a few steps. All required functions are available via the web interface and touch screen - no additional software needs to be installed.

When choosing the ASTi40 version for integration in a switch cabinet, you need the software panel DAST for operation and visualisation of the controller. The system controller then provides the extended range of functions which is available on the AST40 display.
