Parameters

Overview of parameters
The inverter is adapted to a particular application using the corresponding parameters. This
means that each parameter is identified by a parameter number and specific attributes (e.g.
monitoring parameter, write parameter, BICO attribute, group attribute etc.). Within any one
particular inverter system, the parameter number is unique.
Parameters can be accessed using the following operator units:
● BOP
● PC-based commissioning (start-up) tool STARTER.
There are two main types of parameters; those that can be altered and those that are read-
only.

Write parameters

Description
Parameters which can be written into and displayed are indicated by the prefix "P".
These parameters directly influence the behavior of a function. The value of this parameter is
saved in non-volatile memory (EEPROM) as long as the appropriate option was selected
(non-volatile data save). Otherwise, these values are saved in the volatile memory (RAM) of
the processor, which are lost after power failure or power-off/power-on operations.
Examples of the standard notation used throughout our manuals is given below.
