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-
tional
Sets default of 1-23 Motor Frequency, to 50 Hz,
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
Stop,
Ref=Old
Frequency converter powers up in Off State
meaning that motor is stopped after power
up.
Local reference is stored and used after
power-up.
[2] Forced
Stop, Ref=0
Frequency converter powers up in Off State
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.
