Status Word bits
See Chapter 11 "APPENDIX 1 - VACON® IO DATA DESCRIPTION" for status word bit descriptions.
The use of process data depends on the application. In a typical situation, the device is started and
stopped with the Control Word (CW) written by the Master and the Rotating speed is set with
Reference (REF). With PD1…PD16 the device can be given other reference values (e.g. Torque
reference).
With the Status Word (SW) read by the Master, the status of the device can be seen. Actual Value
(ACT) and PD1…PD16 show the other actual values.
Status Word Monitoring values
The Drive Status Word and Protocol Status Word monitoring values will always show the same value
when using Modbus. It is the same value than what is sent to the network.
7.3.2.5.4. ID MAP
Using the ID map, you can read consecutive memory blocks that contain parameters whose IDs 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 IDs in any order. The address range 10601 -
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. The address range 10701 - 10760 contains
the ID Map for 32bit values. Maximum of 30 IDs and ID values can be written and read with single
request except in VACON
®
20 and 20 X/CP it is possible to access only 12 ID value items at a time.
NOTE! 32 bit data not supported in the current version. See Chapter 5 "Installation".
