3.1.2 0-1* Define and Set Up Operations
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.
Use 0-51 Set-up Copy to copy a set-up to the other set-ups.
To avoid conflicting settings of the same parameter within
2 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 5 Parameter Lists.

Text
It is possible to customise the display elements for various
purposes.
Custom Readout
The calculated value to be displayed is based on settings
in 0-30 Custom Readout Unit, 0-31 Custom Readout Min
Value (linear only), 0-32 Custom Readout Max Value,
4-14 Motor Speed High Limit [Hz] and actual speed.

Function:
Select the set-up in which the frequency
converter is to operate.
Set-up 1 is active.
Set-up 2 is active.
Is used for remote selection of set-ups using
digital inputs and the serial communication
port. This set-up uses the settings from
0-12 Link Setups.
Function:
The number of the set-up being edited is
displayed in the LCP, flashing.

digital I/Os
Function:
If the set-ups are not linked, a change between
them is not possible while the motor is running.
When selecting a different setup for operation,
the set-up change does not occur until the
motor is coasted
Copies "not changeable during operation"
parameters from one set-up to the other. It is
possible to switch set-up while the motor is
running.
