Application IDs
Application IDs are parameters that depend on the frequency converter's application. These parameters can
be read and written by pointing the corresponding memory range directly or by using the so-called ID map. It
is easiest to use a straight address if you want to read a single parameter value or parameters with
consecutive ID numbers. It is possible to read 12 consecutive ID addresses.

FB Process data IN
The process data fields are used to control the drive (for example, Run, Stop, Reference, Fault Reset) and to
quickly read actual values (for example, Output frequency, Output current, Fault code). The fields are
structured as follows:
Process Data Master → Slave (max 22 bytes)
