PROFIdrive drive profile

4 PROFIdrive drive profile
The linguistic devices for controlling the drive are extensively independent of the
manufacturer. For this reason, communication between the drive and the
superimposed control system has been standardized in so-called drive profiles.
A drive profile specifies how an electrical drive is controlled via a field bus. It defines
the behavior of the device and the method of accessing the drive data. The following
sub areas in particular are controlled:
● Control and status monitoring
● Standardized parameterization
● Changing operating modes
The profile for electrical drives on PROFIBUS or within PROFINET is called
PROFIDrive.
As a PROFINET IO device, encoTRive supports the PROFIDrive V3.0 profile
The following information's are typically exchanged between a PROFINET IO
controller (e.g. control system) and a drive (e.g. encoTRive):
The drive provides information on its current status (e.g. "Drive running") and possibly
additional information such as the current position, current speed etc. In the other
direction, the control system assigns positioning orders, for example, ("Move at speed
x to position y").
Without profiles such as PROFIDrive, every manufacturer would have to specify his
own protocol for transmitting commands and status messages, and there would be a
corresponding number of applications, which always perform the same task in their
own different ways.

4.1 The object directory

A basic feature of drive profiles is the object directory (OD). All the information
(parameters) relevant to a device is brought together in the object directory. A
parameter is identified by its parameter number (16 Bit). Certain ranges of parameter
numbers are occupied or reserved; others are available for so-called manufacturer-
specific parameters.
Included in the pre-defined parameters are optional parameters and those, which
must be supported by each device that conforms to the profile ("mandatory
parameters").

4.2 PROFIdrive object directory

PROFIDrive uses decimal notation for the parameter numbers. Parameter numbers
900 to 999 and 60000 to 65535 are defined and reserved as profile-specific ranges.
Parameter numbers outside these two ranges are manufacturer-specific.
