At a glance
There are several ways of writing a mobile driving application using Control Expert. The one proposed, uses a Lexium 05 servo drives and Advantys STB island set up on a CANopen network.
Technological choices
The following table shows the technological choices used for the application:
Objects
Choices used
Lexium Operating Mode
Use of the Positioning Mode. This mode allows you to send a target position to the Lexium 05 servo drives through the CANopen network.
Sensor Interface
Use of a STB Advantys. This device is an assembly of distributed I/O, power, and other modules that function together as an island node on an open field bus network
Supervision screen
Use of elements from the library and new objects.
Main supervision program
This program is developed using a sequential function chart (SFC), also called GRAFCET. The various sections and transitions are created in Ladder Diagram (LD) language and in Structured Text language (ST).
NOTE: This example shows PDO and SDO exchange towards a speed drive. However, for speed drive configuration and control, the use of Motion Function Block is recommended.
