DRIVECOM Function Structure Sample Clauses

DRIVECOM Function Structure. This profile defines application functions of variable-speed drive controllers. The application functions are subdivided into - open-loop control functions (e.g. device control, modes of operation) - profile drive functions (e.g. speed-, position functions) - general functions (e.g. device information, block parameterization, malfunction functions). - communication functions (e.g. Read, Write) Free areas are also defined for manufacturer-specific functions. Manufacturer-specific functions Open-loop control functions Drive functions General functions Communication functions Communication medium (Bus system) Each application function is described with the aid of a function block. The hardware response is described by a state machine in the open-loop control functions. This profile takes into account the fact that there may be separate hardware for communication and for tasks related to communication. The drive functions contain the standardised drive functions that communicate with the communication medium through the defined communication functions. Mechanisms by which information is transmitted via the bus system, are laid down in the communications functions. The control functions describe the behaviour of the device and coordinate the various device functions, e.g. device control. In addition to those functions established in the profile, the manufacturer can define additional, manufacturer- specific functions.
