4 Parameter Descriptions

4.1 Parameter Group 0: Operation/Display

0-03 Regional Settings
Option: Function:
In order to meet the needs for different default
settings in different parts of the world, 0-03
Regional Settings, is implemented in the
frequency converter. The selected setting
influences the default setting of the motor
nominal frequency.
[0 ] * Interna- Sets default of 1-23 Motor Frequency, to 50 Hz,
tional shows 1-20 Motor Power in kW.
[1] US Sets default of 1-23 Motor Frequency, to 60 Hz,
shows 1-20 Motor Power in HP.
NOTE
This parameter cannot be changed while
motor runs.
0-04 Operating State at Power-up (Hand Mode)
Option: Function:
This parameter controls whether or not the
frequency converter start running the motor
when powering up after a power down in
Hand mode.
NOTE
If LCP with potentiometer is mounted,
reference is set according to actual
potentiometer value.
[0] Resume Frequency converter starts in same Hand or
Off State as when powered off.
Local reference is stored and used after
power-up.
[1] Forced Frequency converter powers up in Off State
*
Stop, meaning that motor is stopped after power
Ref=Old up.
Local reference is stored and used after
power-up.
[2] Forced Frequency converter powers up in Off State
Stop, Ref=0 meaning that motor is stopped after power
up.
Local reference is set to 0. Thus motor will
not start running before local reference has
been increased.

4.1.1 0-1* Set-up Handling
User-defined parameters and miscellaneous external inputs
(eg. 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-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 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 (eg. 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.
NOTE
Factory Set-up cannot be used as Active Set-up.
0-10 Active Set-up
Option: Function:
Active Set-up controls the motor.
Shifts between set-ups can only happen when
•
the motor is coasted
OR
•
the set-ups between which the shift
happens are linked to each other (see
0-12 Linked Set-ups).
If changing between set-ups that are not linked,
the change will not happen before motor is
coasted.
NOTE
The motor is only considered stopped
when it is coasted.
