3.1 Parameters 
3.1.1  Setting / monitoring parameters and parameter attributes 
The drive inverter is adapted to the particular application using the appropriate 
parameters. This means that each parameter is identified by a parameter number , 
parameter text and specific attributes (e.g. readable, can be written into, BICO 
attribute, group attribute etc.). Within any one particular drive system, the 
parameter number is unique. On the other hand, an attribute can be assigned a 
multiple number of times so that several parameters can have the same attribute. 
For MICROMASTER, parameters can be accessed using the following operator 
units: 
¾ BOP (option) 
¾ AOP (option) 
¾  PC-based commissioning (start-up) tool "Drive Monitor" or "STARTER". These 
PC-based tools are supplied on the CD-ROM. 
The parameter types are the main differentiating feature of the parameters.

Setting parameters 
Parameters which can be written into and read – "P" parameters 
These are activated/de-activated in the individual functions or parameters directly 
influence the behavior of a function. The value of this parameter is saved in a non-
volatile memory (EEPROM) as long as the appropriate option was selected (non-
volatile data save). Otherwise, these values are saved in the non-volatile memory 
(RAM) of the processor, which are lost after power failure or power-off/power-on 
operations.
