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.
4.4 Uploading and Downloading Parameter Settings
4.4.1 Data Transfer from Drive to LCP
Once the setup of a drive is complete, Danfoss recommends storing the data in the LCP or on a PC via VLT® Motion Control Tool
MCT 10.
Stop the compressor before performing this operation.
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 0-01Language.
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 pa-
rameter 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 convert-

[52] Run permissive has a logic AND function related to the terminal which is programmed for [8] Start, [14] Jog, or [20] Freeze output. To start running the compressor, both conditions must be
fulfilled. If [52] Run permissive is programmed on multiple terminals, it only has to be logic 1 on 1 of the terminals for the function to be carried out. The digital output signal for Run Request ([8] Start, [14] Jog, or [20]Freeze output) programmed in parameter group 5-4* Relays is not affected by [52] Run permissive.
N O T I C E
If no [52] Run permissive signal is applied but either run, jog, or freeze commands are activated, the status
line in the display shows either Run Requested, Jog Requested, or Freeze Requested.
[53] Hand start
A signal applied puts the drive into Hand mode as if [Hand On] had been pressed and a normal stop command is overridden. If disconnecting the signal, the compressor stops. To make any other start commands
valid, another digital input must be assigned to [54] Auto Start and a signal applied to this. The [Hand On] and
[Auto On] keys have no impact. The [Off] key overrides [53] Hand start and [54] Auto start. Press either [Hand
On] or [Auto On] to make [53] Hand start and [54] Auto start active again. If there is no signal on [53] Hand start
or [54] Auto start, the compressor stops regardless of any normal start command applied. If a signal is applied
to both [53] Hand start and [54] Auto start, the function is Auto start.
[54] Auto start
A signal applied puts the drive into Auto mode as if [Auto On] had been pressed. See also [53] Hand start.

Functions
5.2.9 Parameter Group 13-** Smart Logic
5.2.9.1 Smart Logic Controller
Smart Logic Control (SLC) is a sequence of user-defined actions (see parameter 13-52 SL Controller Action [x]) executed by the SLC
when the SLC evaluates the associated user-defined event (see parameter 13-51 SL Controller Event [x]) as TRUE.
Events and actions are each numbered and linked in pairs (states). This means that when [0] event is fulfilled (attains the value true),
[0] action is executed. After executing this action, the conditions of [1] event is evaluated. If it is evaluated as true, [1] action is executed, and so on. Only 1 event is evaluated at any time. If an event is evaluated as false, nothing happens (in the SLC) during the
current scan interval and no other events are evaluated. This means that when the SLC starts, it evaluates event [0] (and only [0]
event) each scan interval. Only when [0] event is evaluated true, the SLC executes [0] action and starts evaluating [1] event. It is
possible to program from 1–20 events and actions. When the last event/action has been executed, the sequence starts over again
from [0] event/[0] action.
Illustration 14: Example with 3 Events/Actions
Starting and stopping the SLC
To start or stop the SLC, select [1] On or [2] Off in parameter 13-00 SL Controller Mode. The SLC always starts in state 0 (where it
evaluates [0] event). The SLC starts when the start event (defined in parameter 13-01 Start Event) is evaluated as true (if [1] On is
selected in parameter 13-00 SL Controller Mode). The SLC stops when the stop event (parameter 13-02 Stop Event) is true. Parameter13-03 Reset SLC resets all SLC parameters and starts programming from the beginning.
5.2.9.2 Parameter Group 13-0* SLC Settings
To activate, deactivate, and reset the smart logic control sequence, use the SLC settings. The logic function and comparators are
always running in the background, which opens for separate control of digital inputs and outputs.
