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.

bus, see 5-1* Digital Inputs 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 0-10 Active Set-up).
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.

4.2.7 1-9* Motor Temperature
With an estimated motor temperature monitor the
frequency converter is able to estimate motor temperature
without having a thermistor mounted. It is thus possible to
receive a warning or an alarm, if motor temperature
exceeds upper operational limit.
1-90 Motor Thermal Protection
Option: Function:
Using ETR (Electronic Terminal Relay) the
motor temperature is calculated based on
frequency, speed and time. Danfoss
recommends using The ETR function, if a
thermistor is not present.
NOTE
ETRElectronic Overload calculation is
based on motor data from parameter
group 1-2* Motor Data.
[0] *No Protection Disables temperature monitoring.
[1] Thermistor
Warning
A thermistor connected to either digital or
analog input gives a warning if upper limit
of motor temperature range is exceeded,
(see 1-93 Thermistor Resource).
[2] Thermistor
Trip
A thermistor connected to either digital or
analog input gives an alarm and makes the
frequency converter trip if upper limit of
motor temperature range is exceeded, (see
1-93 Thermistor Resource.
[3] ETR Warning If calculated upper limit of motor
temperature range is exceeded, a warning
occurs.
[4] ETR Trip If 90% of calculated upper limit of motor
temperature range is exceeded, an alarm
occurs and the frequency converter trips.
NOTE
When the ETR function has been selected the drive will
store the recorded temperature at power down and this
temperature will resume at power up regardless of the
elapsed time. Changing 1-90 Motor Thermal Protection back
to [0] No Protection will reset the recorded temperature.
1-93 Thermistor Resource
Option: Function:
Select the thermistor input terminal.
[0] *None No thermistor is connected.
[1] Analog
Input 53
Connect thermistor to analog input terminal
53.
