Process Data (Cyclic Data Exchange)

7.6.1

General

Drive control is per default performed through the cyclic data exchange channel. DriveControl,
DriveStatus, Setpoint and Actual Values are sent as IO DATA telegrams on PROFIBUS. These tele-
grams are transformed and mapped to the main unit parameters by the option board.
The Process Data map is based entirely on the requirements of PROFIdrive and the end user by
means of User Parameterization Data. The active process data is mapped in the configuration
tool, where PROFIdrive profile specific signals are specified using signal numbers 1 - 1000 and
vendor specific signals are specified using signal numbers 1001...59999.
For all configurations, the default for the first IO_DATA items in each direction will be DriveCon-
trol and DriveStatus respectively.
7.6.2

Signals

Each IO DATA channel is assigned a signal which is mapped to an inverter parameter. Thus
PROFIdrive parameters that are to be exchanged as IO DATA (i.e. Process Data) must be assigned
a unique signal number.
Signal numbers 1...1000 are reserved for standard Drive Profile parameters, while signals
1001...59999 are used for vendor specific parameters.
The table below shows the implementation of the PROFIdrive signal list.
