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 dif-
ferent parts of the world, par. 0-03,
Regional Settings , is imple-
mented in the frequency converter. The selected setting
influences the default setting of the motor nominal frequency.
[0 ]
*
International Sets default of par. 1-23, Motor Frequency , to 50 Hz.
[1] US Sets default of par. 1-23,
Motor Frequency , to 60 Hz.
NB!
This parameter cannot be adjusted while motor
runs.
0-04 Operating State at Power-up (Hand Mode)
Option: Function:
This parameter controls whether or not the frequency converter
should start running the motor when powering up after a power
down in Hand mode.
NB!
If LCP with potmeter is mounted, reference is set
according to actual potmeter 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 Micro
Drive FC 51 contains 2 set-ups,
Set-up1 and Set-up 2 .
VLT Micro Drive FC 51 4. Parameter Descriptions
MG.02.C2.02 - VLT®is a registered Danfoss trademark 13

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.
NB!
FactorySet-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
•themotoriscoasted
OR
• the set-ups between which the shift happens are linked
to each other (see par. 0-12,
Linked Set-ups ).
If changing between set-ups that are not linked, the change will
not happen before motor is coasted.
NB!
The motor is only considered stopped when it is
coasted.
[1 ] *
Set-up 1 Set-up 1 is active.
[2] Set-up 2
Set-up 2 is active.
[9] Multi Set-up Select the active set-up via digital input and/or bus, see par.
5-1* choice [23].
0-11 Edit Set-up
Option: Function:
The
Edit Set-up is for updating parameters in the frequency
converter from either LCP or bus. It can be identical or different
from the
Active Set-up .
All set-ups can be edited during operation, independently of the
active set-up.
[1 ]
*
Set-up 1 Update parameters in Set-up 1 .
[2] Set-up 2 Update parameters in
Set-up 2 .

[9] Active Set-up Update parameters in set-up selected as Active Set-up (see par.
0-10).
0-12 Link Set-ups
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 motor runs.
[1 ]
*
Linked Copy parameters “not changeable during operation” parameter
values into presently selected
Edit Set-up .
NB!
This parameter cannot be changed while motor
runs.
4.1.2. 0-4* LCP Keypad
The frequency converter can operate in the following three modes: Hand , Off and Auto .
Hand: The frequency converter is locally operated and does not allow any remote control. By
activating Hand a start signal is given.
OFF: The frequency converter stops with a normal stop ramp. When Off is chosen the frequency
converter can only be started by pressing either Hand or Auto on the LCP.
Auto: In Auto-mode the frequency converter can be remote controlled (bus/digital).
