3.2.3 0-1* Set-up Operations
Define and control the individual parameter set-ups.
The frequency converter has four parameter setups that can be programmed independently of each other. This makes the frequency converter very
flexible and able to meet the requirements of many different VLT HVAC Drive system control schemes often saving the cost of external control equipment.
For example these can be used to program the frequency converter to operate according to one control scheme in one setup (e.g. daytime operation)
and another control scheme in another setup (e.g. night set back). Alternatively they can be used by an AHU or packaged unit OEM to identically program
all their factory fitted frequency converters for different equipment models within a range to have the same parameters and then during production/
commissioning simply select a specific setup depending on which model within that range the frequency converter is installed on.
The active setup (i.e. the setup in which the frequency converter is currently operating) can be selected in par. 0-10
Active Set-up
and is displayed in
the LCP. Using Multi set-up it is possible to switch between set-ups with the frequency converter running or stopped, via digital input or serial commu-
nication commands (e.g. for night set back). If it is necessary to change setups whilst running, ensure par. 0-12

even if change of set up
whilst running is required, but for very complex applications, using the full flexibility of the multiple setups, it may be required. Using par. 0-11
Programming
Set-up
it is possible to edit parameters within any of the setups whilst continuing the frequency converter operation in its Active Setup which can be a
different setup to that being edited. Using par. 0-51
Set-up Copy
it is possible to copy parameter settings between the set-ups to enable quicker com-
missioning if similar parameter settings are required in different set-ups.

Option: Function:
Select the set-up in which the frequency converter is to operate.
Use par. 0-51
Set-up Copy
to copy a set-up to one or all other set-ups. To avoid conflicting settings
of the same parameter within two different set-ups, link the set-ups together using par. 0-12

. Stop the frequency converter before switching between set-ups where parameters
marked ‘not changeable during operation’ have different values.
Parameters which are ‘not changeable during operation’ are marked FALSE in the parameter lists in
the section

[0] Factory setup Cannot be changed. It contains the Danfoss data set, and can be used as a data source when
returning the other set-ups to a known state.

0-11 Programming Set-up
Option: Function:
Select the set-up to be edited (i.e. programmed) during operation; either the active set-up or one
of the inactive set-ups. The set-up number being edited is displayed in the LCP in (brackets).

[9] * Active Set-up (i.e. the set-up in which the frequency converter is operating) can also be edited during operation.
Editing parameters in the chosen setup would normally be done from the LCP but it is also possible
from any of the serial communication ports.
