3.1.2 K-1# Keypad 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 very flexible and able to meet the
requirements of many different HVAC 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 1 control
scheme in 1 set-up (for example daytime operation) and
another control scheme in another set-up (for example
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 (that is the set-up in which the frequency
converter is currently operating) can be selected in
parameter K-10 Active Set-up and is displayed in the keypad.
Using [9] 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 set back). If it is necessary to change
setups while running, ensure that
parameter K-12 This Set-
up Linked to is programmed as required. For most HVAC
applications it is not necessary to program
parameter K-12 This Set-up Linked to even if change of set
up while running is required, but for very complex
applications, using the full flexibility of the multiple set-
ups, it may be required. Using
parameter K-11 Edit 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 which can be a different set-up to the one
being edited. Using
parameter K-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.
If a set-up is changed via a fieldbus, it takes up to 5 s
before the new values are reflected via the fieldbus.
K-10 Active Set-up
Option: Function:
Select the set-up in which the frequency
converter is to operate.
Use parameter K-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 K-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.
K-10 Active Set-up
Option: Function:
Parameters which are not changeable during
operation are marked FALSE in
chapter 5 Parameter Lists .
[0] Factory
setup
Cannot be changed. It contains the GE data set,
and can be used as a data source when
returning the other set-ups to a known state.
[1]
*
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 selection of set-ups using
digital inputs and the serial communication
port. This set-up uses the settings from
parameter K-12 This Set-up Linked to .
K-11 Edit Set-up
Option: Function:
Select the set-up to be edited (that is
programmed) during operation; either the
active set-up or 1 of the inactive set-ups. The
set-up number being edited is shown in the
keypad in brackets.
[0] Factory
setup
Cannot be edited, but it is useful as a data
source to return the other set-ups to a known
state.
[1] Set-up 1 [1] Set-up 1 to [4] Set-up 4 can be edited freely
during operation, independently of the active
set-up.
[2] Set-up 2
[3] Set-up 3
[4] Set-up 4
[9]
*
Active Set-
up
The set-up in which the frequency converter is
operating can be edited during operation.
Editing parameters in the selected set-up
would normally be done from the keypad, but
it is also possible from any of the serial
communication ports.
K-12 This Set-up Linked to
Option: Function:
Use this parameter only if a change of set-ups
is required while the motor is running. This
parameter ensures that parameters which are
not changeable during operation have the
same setting in all relevant set-ups.
To enable conflict-free changes from 1 set-up to
another while the frequency converter is
running, link set-ups containing parameters
which are not changeable during operation.
