Table 27. Status Word bits B29-B31, descriptions of bit connections
The use of process data depends on the application. In a typical situation, the device is started and
stopped with the ControlWord (CW) written by the Master and the Rotating speed is set with
Reference (REF). With PD1…PD8 the device can be given other reference values (e.g. Torque
reference).
With the StatusWord (SW) read by the Master, the status of the device can be seen. Actual Value
(ACT) and PD1…PD8 show the other actual values.

ID map
Using the ID map, you can read consecutive memory blocks that contain parameters whose ID's are
not in a consecutive order. The address range 10501 - 10530 is called 'IDMap', and it includes an
address map in which you can write your parameter ID's in any order. The address range 10601 to
10630 is called 'IDMap Read/Write,' and it includes values for parameters written in the IDMap. As
soon as one ID number has been written in the map cell 10501, the corresponding parameter value
can be read and written in the address 10601, and so on.
IDMap IDs can be also configured from the panel or VaconLive PC tool. IDmap menu is located under
Modbus TCP and Modbus RTU settings. See details in chapters 5.1 and 5.2.2.
Table 29. IDMap initialization
Once the IDMap address range has been initialized with any parameter ID number, the parameter
value can be read and written in the IDMap Read/Write address range address IDMap a 100.
