General Information

Inverter parameters can be accessed acyclically by means of the PROFIdrive Parameter Protocol.
The master issues a parameter request to the option board. The option board processes the re-
quest. Meanwhile the master repeatedly tries to read the parameter response, but an error mes-
sage will be returned until the request is fully processed by the module, after which the master
can read the response.
Translation of signal numbers
Signal numbers used in the inverter do not directly translate to signal numbers (PNUs) used on
PROFIBUS. An offset is added to avoid ambiguous numbering on PROFIBUS, where parameters
and monitor data have different PNU numbers.
The array below presents a summary of the signal number translation. For a complete presenta-
tion of how to translate the signal numbers for the option board drive profile parameters, see
"Translation of Signal Numbers" on page 147.

Some of these parameters can be mapped for cyclic data exchange, see "Translation of Signal Num-
bers" on page 147.

These parameters can either be accessed (as acyclic data) as an array, with offset 13288d, or can
each entry in the array be mapped as a separate parameter with offset 15336d (as acyclic and/or
cyclic data).
