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.

Function:
Select the set-up in which the frequency converter
is to operate.
Use 0-51 Set-up Copy 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 0-12 Link Setups. 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.
Set-up 1 Set-up 1 is active.
*
Set-up 2 Set-up 2 is active.
Multi Is used for remote selection of set-ups using digital
Set-up inputs and the serial communication port. This set-
up uses the settings from 0-12 Link Setups.
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- (i.e. the set-up in which the frequency converter
*
up is operating) can also be edited during
operation.
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.
Not Leaves parameters unchanged in both set-ups
linked and cannot be changed while motor runs.
Linked Copies "not changeable during operation"
*
parameters from one set-up to the other, so they
are identical in both set-ups.
