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]/[Off] 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:

Defines if the local reference unit is shown
in terms of the motor shaft speed (in
RPM/Hz) or as percent.

3.2.2 0-1* Set-up Operations

Define 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 flexible in use and able to meet
the requirements of many different 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-fitted frequency converters for
different equipment models within a range to have the
same parameters. During production/commissioning, select
a specific 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

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 flexibility of the multiple set-ups,
it may be required. Using

parameter 0-11 Programming Set-

, 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 different 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 different 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 conflicting
settings of the same parameter within 2
different 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
