The illustration [2-8] shows the different functional ranges within a typical application in a simpli-
fied way.
Application
Setpoints and control signals are read into the application and application-specific functions as set-
point conditioning, process control, and process monitoring are implemented by a corresponding
function block interconnection.
• Here, you can access comprehensive Lenze function libraries, which contain, among other
things, process controllers, arithmetic functions, logic modules as well as ramp generators and
integrators.
• Actual values and status signals can be provided via the output terminals of the controller and
via ports when communicating via a network.
• All parameters are selected and displayed in the real machine or material units.
Motor control
Here, all control and monitoring functions of the specific motor functions are implemented.
• All parameters are selected and displayed in motor units.
• In the function block editor, the motor control is accessed via the motor interface (system block
LS_MotorInterface).
Device control
The device control contains all control and monitoring functions of the controller.
• In the function block editor, the device control is accessed via the drive interface (system block
LS_DriveInterface).
• The machine constants for the motor end are also entered via the drive interface.
Basic drive functions (Motion Control)
Standard functions of the motion control (e.g. manual jog/inching, homing, brake control, positio-
ning) are already included in the firmware of the controller as basic drive functions.
• In the function block editor, the basic drive functions are accessed via system blocks.
• The basic drive functions which are required in the interconnection in the form of a system block
depend on the drive task to be solved.
• All parameters are selected and displayed in machine units. Thus, the user is able to work with
the familiar units.
