4.3.3.4 Changes Made

Changes Made lists all parameters changed from default settings.

•The list shows only parameters which have been changed in the current edit set-up.

•Parameters which have been reset to default values are not listed.

•The message Empty indicates that no parameters have been changed.

4.3.4 Main Menu

The Main Menu is used for programming all parameters. The Main Menu parameters can be accessed immediately unless a password has been created via parameter 0-60 Main Menu Password. For most applications, it is not necessary to access the Main Menu parameters. The Quick Menu provides the simplest and quickest access to the typical required parameters.

5 Parameter Descriptions and Functions

5.1 Introduction to Parameters

The * in parameter numbers indicates a group or subgroup of parameters for which the first 1 or 2 numbers are the same. For example, 0-** indicates the group of parameters that all start with 0. 0-0* indicates the subgroup of parameters that share the first 2 numbers, which are 0-0.

An asterisk (*) after an option number indicates the default option. For example, [0]* English is the default option for parameter 0-01 Language.

Organization of the parameter chapter

The VLT® Compressor DriveCDS 803 uses 2 different software version depending on the power range. The 6–10 kW drives use one software version, while 18–30 kW drives use another software version. The chapter is split into the following 3 sections:

•Common Parameters: This section contains all available parameters shared across all power ranges.

•6–10 kW Specific Parameters: This section contains the parameters available only for 6–10 kW drives.

•18–30 kW Specific Parameters: This section contains the parameters available only for 18–30 kW drives.

5.1.1 Reading the parameter table

This Programming Guide includes parameter and options tables. These descriptions explain how to read the parameter and options tables.

Illustration 7: Parameter Table

1 indicates the value set in factory. Expressionlimit means the default value is not a fixed value and may link to power size and parameter dependency.

2 indicates whether the parameter type is option or range. Option means that the user is presented with a predefined selection to choose between. Range means that the user can select any value within the specified range.

3 indicates the manner of parameter set-ups. 2 setups means that the parameter can be set individually in each of the 2 setups. For example, 1 single parameter can have 2 different data values. 1 setup indicates that the data value is the same in all setups.

4 refers to the conversion index. Parameter values are transferred as whole numbers only. Conversion factors are therefore used to transfer decimals. If a value is transferred as 100 and a conversion index of -1, the real value is 10.0.

5 indicates the different data types for the parameters.

6 indicates whether the parameter value can be changed while the drive is in operation. False indicates that the frequency converter must be stopped before a change can be made.
