9. Setting the product

To make a correct programming, it is often necessary to make
settings in several submenus. The programmed data is saved
internally in the frequency converter.
It is possible to make a backup of the data by uploading the data
to the operating panel"s memory.
The menus are accessed or changed from [Main Menu] or
[Favourites] on the operating panel. However, not all menus are
available in [Favourites].
All settings that have been made are visible in [Favourites] > "Q5
- Changes Made".
See 8.1 Operating panel and 8.2 Menu

9.1 First-time setup via the startup guide

The startup guide starts automatically the first time the product is
switched on or after startup of the frequency converter. The guide
enables quick configuration of basic pump- and application
parameters.
1. Follow the on-screen instructions to complete the
commissioning of the frequency converter. Some data from
the motor nameplate is needed.
Reactivate the start-up guide by pressing
[Favourites] > "Q4" - "Run start-up guide".

9.2 Uploading or downloading of data

It is possible to download stored data to another frequency
converter.
2. Navigate to "0-5* Copy/Save", and press [OK].
3. Press [OK] to activate "0-50 LCP Copy".
4. Press [Up] to select "[1] All to LCP" to upload data to the
operating panel, or
5. select "[2] All from LCP" to download data from the operating
panel.
6. Press [OK]. A progress bar shows the uploading or
downloading progress.

9.3 Asynchronous motor setup

To set an asynchronous motor manually in [Main menu], enter the
following motor data available on the motor nameplate.
• "1-20 Motor Power [kW]" or "1-21 Motor Power [HP]"
• "1-22 Motor Voltage"
• "1-23 Motor Frequency"
• "1-24 Motor Current"
• "1-25 Motor Nominal Speed"
• "1-29 Automatic Motor Adaptation (AMA)".

9.4 Checking the motor rotation

There is a risk of damage to the pumps or the
compressors if the motor is running in the wrong
direction. Before starting the frequency converter,
check the motor rotation.
1. Navigate to "1-28 Motor Rotation Check", and press [OK].
2. Scroll to "[1] Enable".
The following text appears: "Note! Motor may run in wrong
direction".
3. Press [OK].
4. Follow the on-screen instructions.
To change the direction of rotation, remove power to the
frequency converter and wait before touching the product. See
waiting time in section 4. Installation
• Reverse the connection of any 2 of the 3 motor wires on the
motor or frequency-converter side of the connection.

requirements.

9.5 Permanent-magnet motor setup

To set a permanent-magnet motor manually in [Main menu], enter
the motor data available on the motor nameplate.
1. Activate PM motor operation "1-10 Motor Construction", select
"[1] PM, non salient SPM."
2. Set "0-02 Motor Speed Unit" to "[0] RPM".
Programme the following parameters in the listed order:
1. "1-24 Motor Current"
2. "1-26 Motor Cont. Rated Torque"
3. "1-25 Motor Nominal Speed"
4. "1-39 Motor Poles"
5. "1-30 Stator Resistance (Rs)". Enter line to common stator
winding resistance (Rs). If only line-line data is available,
divide the line-line value by 2 to achieve the line-common
(starpoint) value.
6. "1-37 d-axis Inductance (Ld)". Enter line to common direct
axis inductance of the PM motor. If only line-line data is
available, divide the line-line value by 2 to achieve the line-
common (starpoint) value.
7. "1-40 Back EMF at 1000 RPM". Enter line-to-line back EMF of
the PM motor at 1000 RPM mechanical speed (RMS value).
Back EMF is the voltage generated by a PM motor when no
frequency converter is connected and the shaft is turned
externally. Back EMF is normally specified for nominal motor
speed or for 1000 RPM measured between 2 lines. If the
value is not available for a motor speed of 1000 RPM,
calculate the correct value as follows: If back EMF is for
example 320 V at 1800 RPM, it can be calculated at 1000
RPM as follows: Back EMF = (Voltage / RPM)*1000 = (320/
1800)*1000 = 178. This is the value that must be programmed
for "1-40 Back EMF at 1000 RPM".
9.5.1 Test motor operation
1. Start the motor at low speed (100-200 RPM). If the motor does
not turn, check the installation, general programming, and
motor data to ensure that it is correct.
2. Check if the start function in "1-70 PM Start Mode" fits the
application requirements.

9.6 Synchronous reluctance motor setup

To set a synchronous reluctance motor manually in [Main menu],
enter the following motor data available on the motor nameplate:
• "1-10 Motor Construction"
• "1-23 Motor Frequency"
• "1-24 Motor Current"
• "1-25 Motor Nominal Speed"
• "1-26 Motor Cont. Rated Torque"
• "1-29 Automatic Motor Adaptation (AMA)".

9.7 Automatic Energy Optimisation (AEO)

AEO is not relevant for permanent-magnet motors.
AEO is a procedure which minimises voltage to the motor,
thereby reducing energy consumption, heat, and noise.
To activate AEO, set "1-03 Torque Characteristics" to "[2] Auto
Energy Optim. CT" or "[3] Auto Energy Optim. VT".
