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.) control the
functionality of the adjustable frequency drive.
A complete set of all parameters controlling the adjustable
frequency drive is called a set-up. The adjustable frequency
drive contains 2 set-ups, Set-up 1 and Set-up 2.
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 adjustable frequency drive 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 the
adjustable frequency drive. Motor data for various
motors can be placed in different set-ups.
•
Rapidly change settings of adjustable frequency
drive and/or motor, for example, while the motor
is running. 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 adjustable
frequency drive 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 adjustable frequency drive 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
5 Parameter Lists .
[1] Set-up 1 Set-up 1 is active.
[2] Set-up 2 Set-up 2 is active.
[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
0-12 Link Setups .
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.
[1] Set-up 1 Set-up 1 [1] to Set-up 2 [2] can be edited freely
during operation, independently of the active
set-up.
[2] Set-up 2
[9] Active Set-
up
(i.e., the set-up in which the adjustable
frequency drive 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 the motor is
running.
