3.1.2 0-1* Define and set-up Operations
Define and control the individual parameter set-ups. User
defined parameters and miscellaneous external inputs (e.g.
bus, LCP, analog/digital inputs, feedback, etc.) controls the
functionality of the frequency converter.
A complete set of all parameters controlling the frequency
converter is called a set-up. The frequency converter
contains 2 set-ups, Set-up1 and Set-up2. Furthermore, a fixed
set of factory settings can be copied into one or more set-
ups.
Some of the advantages of having more than one set-up in
the frequency converter are:
•
Run motor in one set-up (Active Set-up) while
updating parameters in another set-up (Edit Set-
up)
•
Connect various motors (one at a time) to
frequency converter. Motor data for various motors
can be placed in different set-ups.
•
Rapidly change settings of frequency converter
and/or motor while motor is running e.g.. Ramp
time or preset references) via bus or digital inputs.
The Active Set-up can be set as Multi Set-up where the active
set-up is selected via input on a digital input terminal and/or
via the bus control word.
0-10 Active Set-up
Option:
Function:
Select the set-up in which the frequency converter
is to operate.
Use
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
. 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 the parameter lists
in the section
Parameter Lists
.

0-11 Programming Set-up
Option:
Function:
Select the set-up to be edited (i.e. programmed)
during operation; either the active set-up or the
inactive set-up. The set-up number being edited
is displayed in the LCP flashing.

Set-up 1
Set-up 1
[1] to
Set-up 2
[2] can be edited freely
during operation, independently of the active
set-up.

Set-up 2

*
Active Set-
up
(i.e. the set-up in which the frequency converter
is operating) can also be edited during
operation.
0-12 Link Setups
Option:
Function:
The link ensures synchronizing of the “not
changeable during operation” parameter values
enabling shift from one set-up to another during
operation.
If the set-ups are not linked, a change between
them is not possible while the motor is running.
Thus the set-up change does not occur until the
motor is coasted.
[0]
Not
linked
Leaves parameters unchanged in both set-ups
and cannot be changed while motor runs.
[20]
*
Linked
Copies “not changeable during operation”
parameters from one set-up to the other, so they
are identical in both set-ups.
