Danfoss VLT AQUA Drive FC 200 Programming Manual page 29

Parameter Description
0-03 Regional Settings
Option: Function:
This parameter cannot be adjusted while the
motor is running.
The display showing depends on settings in
0-02 Motor Speed Unit and 0-03 Regional Settings.
The default setting of 0-02 Motor Speed Unit and
0-03 Regional Settings depends on which region
of the world the adjustable frequency drive is
supplied to but can be re-programmed as
required.
[0] Interna- Sets 1-20 Motor Power [kW] units to [kW] and the
tional default value of 1-23 Motor Frequency [50 Hz].
[1] North Sets 1-21 Motor Power [HP] units to HP and the
America default value of 1-23 Motor Frequency to 60 Hz.
The settings not used are made invisible.
0-04 Operating State at Power-up
Option: Function:
Select the operating mode upon reconnection of
the adjustable frequency drive to AC line voltage
after power-down when operating in Hand (local)
mode.
[0] Resume Resumes operation of the adjustable frequency
drive 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 adjustable frequency drive
was powered down.
[1] Forced Uses [1] Forced stop, ref=old to stop the
stop, adjustable frequency drive but at the same time
ref=old retain in memory the local speed reference prior
to power-down. After AC line voltage is
reconnected and after receiving a start command
(pressing [Hand On] or Hand Start command via
a digital input) the adjustable frequency drive
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
Unit
[1] %

VLT AQUA Drive Programming Guide
3.2.2 0-1* Set-up Operations
Define and control the individual parameter set-ups.
The adjustable frequency drive has four parameter set-ups
that can be programmed independently of each other. This
makes the adjustable frequency drive very flexible and
able to meet the requirements of many different AQUA
system control schemes, often saving on the costs of
external control equipment. For example, these can be
used to program the adjustable frequency drive 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 setback). Alternatively, they can be used
by an AHU or packaged unit OEM to identically program
all their factory-fitted adjustable frequency drives for
different equipment models within a range to have the
same parameters and then during production/commis-
sioning simply select a specific set-up depending on which
model within that range the adjustable frequency drive is
installed on.
The active set-up (i.e., the set-up in which the adjustable
frequency drive 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
adjustable frequency drive running or stopped, via digital
input or serial communication commands (e.g., for night
setback). If it is necessary to change set-ups during
operation, 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 during operation is required;
however, for very complex applications, using the full
flexibility of the multiple set-ups may be required. Using
0-11 Programming Set-up, it is possible to edit parameters
within any of the set-ups while continuing adjustable
frequency drive 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.
