Danfoss VLT AQUA Drive FC 202 Programming Guide

0-04 Operating State at Power-up
Option: Function:
Select the operating mode after reconnection of
the frequency converter to mains voltage after
power-down when operating in hand-on (local)
mode.
[0] * Resume Resumes operation of the frequency converter
maintaining the same local reference and the
same start/stop condition. The start/stop
condition is applied by [Hand On]/[O] on the
LCP or local start via a digital input as before
the frequency converter was powered down.
[1] Forced
stop,
ref=old
Stops the frequency converter, but at the same
time retains the local speed reference before
power-down in the memory. After mains
voltage is reconnected and after receiving a
start command (pressing [Hand On] or local
start command via a digital input), the
frequency converter restarts and operates at the
retained speed reference.
0-05 Local Mode Unit
Option: Function:
Denes if the local reference unit is shown
in terms of the motor shaft speed (in
RPM/Hz) or as percent.
[0] * As Motor

3.2.2 0-1* Set-up Operations
Dene and control the individual parameter set-ups.
The frequency converter has 4 parameter set-ups that can
be programmed independently of each other. This makes
the frequency converter exible in use and able to meet
the requirements of many dierent water system control
schemes often saving the cost of external control
equipment. For example, the set-ups can be used to
program the frequency converter to operate according to 1
control scheme in 1 set-up (for example daytime
operation) and another control scheme in another set-up
(for example night setback). Alternatively, they can be used
by an air handling unit or an OEM unit to identically
program all their factory-tted frequency converters for
dierent equipment models within a range to have the
same parameters. During production/commissioning, select
a specic set-up depending on the frequency converter
model.
Select the active set-up (that is, the set-up in which the
frequency converter is operating) in parameter 0-10 Active
Set-up. The LCP then shows the selected active set-up.
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 (for
example for night setback). If it is necessary to change set-
ups while running, ensure that parameter 0-12 This Set-up
Linked to is programmed as required. For most water/
wastewater applications, it is not necessary to program
parameter 0-12 This Set-up Linked to even if change of set-
up is required when running. However, for complex
applications using the full exibility of the multiple set-ups,
it may be required. Using parameter 0-11 Programming Set-
up, it is possible to edit parameters within any of the set-
ups while continuing the frequency converter operation in
its active set-up. The active set-up can be a dierent set-up
to the one being edited. Using parameter 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 dierent set-ups.
0-10 Active Set-up
Option: Function:
Select the set-up in which the frequency
converter is to operate.
Use parameter 0-51 Set-up Copy to copy a set-up
to 1 or all other set-ups. To avoid conicting
settings of the same parameter within 2
dierent set-ups, link the set-ups using
parameter 0-12 This Set-up Linked to. Stop the
frequency converter before switching between
set-ups where parameters marked not
changeable during operation have dierent
values.
Parameters which are not changeable during
operation are marked FALSE in
chapter 4 Parameter Lists.
[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.

Set-up 1 [1] Set-up 1 to [4] Set-up 4 are the 4 parameter
set-ups within which all parameters can be
programmed.
[2] Set-up 2
[3] Set-up 3
[4] Set-up 4
[9] Multi Set-
up
Is used for remote set-up selections using digital
inputs and the serial communication port. This
set-up uses the settings from
parameter 0-12 This Set-up Linked to.
