PCD Reference Parameter

Process data may be scaled by a parameter, e.g. the max reference of 0x4000 (in %) depends

on the setting of parameter “X”.

To enable the master to calculate the “real” value of the process data, it has to know the value

of parameter “X”, and therefore the process data must deliver a reference to parameter “X”.

Field PCD Normalization

The field PCD normalization must express, in any case, the value that represents the 100 %, i.e.

the normalization delivered back must be the set bit 15 and a value of 0xe (14, 2

= 0x4000),

and the result must be 0x800e.

Complete Description

Returns the complete parameter description with the fields 1 to 12 in order. Length = 46 byte.

5.2.18. Attribute Text (30H)

For some frequency converter parameters a descriptive text is available, which can be read using

this attribute. The availability of a text description for a parameter is indicated by a bit set in the

Identifier (ID) Parameter Description element, which can be read out by the Description Attribute

(20H) sub-index = 1. If bit 10 is set, a descriptive text exists for each value of the parameter.

As an example, par. 0-01

Language

has settings from 0 to 5. For each of these values a specific

text exists: 0 = ENGLISH, 2 = DEUTSCH, etc.

5.2.19. Format

Specifies the format type for each parameter (word, byte, etc.), see below.
