3.1Parameters

3.1.1Setting / 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:

BOP (option)

AOP (option)

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.

		Parameter
	Read (r....)		Write/Read (P....)
"normal"	BICO output	"normal"	BICO input
Read parameters		Write-/Read parameters

Setting parameters

Parameters which can be written into and read – "P" parameters

These parameters are activated/de-activated in the individual functions and 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.

Notation:
