Parameter Description
The settings not used are made invisible.
0-04 Operating State at Power-up
Option: Function:
Select the operating mode upon reconnection
of the frequency converter to mains voltage
after power down when operating in Hand
(local) mode.
[0] Resume Resumes operation of the frequency converter
*
maintaining the same local reference and the
same start/stop condition (applied by [Hand
On]/[Off] on the LCP or Hand Start via a digital
input as before the frequency converter was
powered down.
[1] Forced Uses [1] Forced stop, ref=old to stop the
stop, frequency converter but at the same time
ref=old retain in memory the local speed reference
prior to power down. After mains voltage is
reconnected and after receiving a start
command (pressing [Hand On] or Hand Start
command via a digital input) the frequency
converter restarts and operates at the retained
speed reference.
0-05 Local Mode Unit
Option: Function:
Defines if the local reference unit should
be displayed in terms of the motor shaft
speed (in RPM/Hz) or as percent.
[0] As Motor Speed

3.2.2 0-1* Set-up Operations
Define and control the individual parameter set-ups.
The frequency converter has four parameter set-ups that
can be programmed independently of each other. This
makes the frequency converter very flexible and able to
meet the requirements of many different AQUA 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 set-up (e.g. daytime operation) and another
control scheme in another set-up (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
set-up depending on which model within that range the
frequency converter is installed on.
The active set-up (i.e. the set-up in which the frequency
converter is currently operating) can be selected in
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 communication commands (e.g. for night set
back). If it is necessary to change set-ups whilst running,
ensure 0-12 This Set-up Linked to is programmed as
required. For the majority of AQUA applications it will not
be necessary to program 0-12 This Set-up Linked to even if
change of set up whilst running is required, but for very
complex applications, using the full flexibility of the
multiple set-ups, it may be required. Using
0-11 Programming Set-up it is possible to edit parameters
within any of the set-ups whilst continuing the frequency
converter operation in its Active Set-up which can be a
different set-up to that being edited. Using 0-51 Set-up
Copy it is possible to copy parameter settings between the
set-ups to enable quicker commissioning if similar
parameter settings are required in different set-ups.

Function:
Select the set-up in which the frequency
converter is to operate.
Use 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 0-12 This Set-up Linked to. 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 4 Parameter
Lists.
Factory Cannot be changed. It contains the Danfoss
setup data set, and can be used as a data source
when returning the other set-ups to a known
state.
