6.3.5 Vacon Application IDs
Application IDs are parameters that depend on the drive's application. These parameters can be
read and written by pointing the corresponding memory range directly or by using the so-called ID
map (more information below). The easiest way to read a single parameter value or parameters with
consecutive ID numbers is to use a straight address. It is possible to read 30 consecutive ID
addresses. Notice that the operation will fail if even one of the consecutive IDs do not exist for such
case see Chapter 6.3.8 ID map.
Parameters which have 32 bit value can be read from their own range. For example, if you want to
read the value for ID 864 (FB Status Word), the address must be set to 21726. This address value
comes from values: 20000 + ((ID -1) * 2). The ID value is reduced with one because of zero-based
addressing and the result is multiplied with 2 because one 32 bit value will take two (16 bit)
addresses.
6.3.6 FB Process data IN
The process data fields are used to control the drive (e.g. Run, Stop , Reference, Fault Reset) and to
quickly read actual values (e.g. Output frequency, Output current, Fault code). The fields are
structured as follows:
Table 20. Application IDs
Address range Purpose Application ID
0001-2000 16 bit application parameters 1-2000
2200-10000 16 bit application parameters 2200-10000
20001-40000 32 bit application parameters 1-10000
