See chapter 5.7.1.3.5.1. Eaton application IDsApplication IDs are parameters that depend on the drive’sapplication. These parameters can be read and written bypointing the corresponding memory range directly or byusing the so-called ID map (more information below). Theeasiest way to read a single parameter value or parameterswith consecutive ID numbers is to use a straight address.It is possible to read 30 consecutive ID addresses. Noticethat the operation will fail if even one of the consecutive IDsdo not exist.Parameters which have 32 bit value can be read from theirown range. For example, if you want to read the value forID 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-basedaddressing and the result is multiplied with 2 becauseone 32 bit value will take two (16 bit) addresses.Table 19.

FB process data inThe process data fields are used to control the drive(e.g. Run, Stop, Reference, Fault Reset) and to quickly readactual values (e.g. Output frequency, Output current, Faultcode). The values in these indexes can be read and written.The fields are structured as follows.
