1-39 Motor Poles
5.
1-30 Stator Resistance (Rs)
. Enter the line-to-common stator
winding resistance (Rs). If only line-to-line data is available,
divide the line-to-line value by two to get the line-to-common
(starpoint) value.
6.
1-37 d-axis Inductance (Ld)
. Enter the line-to-common direct-
axis inductance of the PM motor. If only line-to-line data is
available, divide the line-to-line value by two to get the line-to-
common (starpoint) value.
7.
1-40 Back EMF at 1000 RPM
. Enter the 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 two 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 Testing the motor operation
1. Start the motor at low speed (100-200 RPM). If the motor does
not turn, make sure that the installation, general
programming and motor data are correct.
2. Make sure that the start function in
1-70 PM Start Mode
fits the
application requirements.
9.6 Setting a synchronous reluctance motor
To set a synchronous reluctance motor manually in the [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 Setting a permanent-magnet assisted synchronous
reluctance motor
To set a permanent-magnet assisted synchronous reluctance motor
manually in the [Main menu], enter the motor data available on the
motor nameplate.
1. Set
0-02 Motor Speed Unit
to
[0] RPM
, and program the
following parameters in the ordered list:
a.
1-24 Motor Current
b.
1-26 Motor Cont. Rated Torque
c.
1-25 Motor Nominal Speed
d.
1-39 Motor Poles
e.
1-30 Stator Resistance (Rs)
. Enter the line-to-common
stator winding resistance (Rs). If only line-to-line data is
available, divide the line-to-line value by two to get the line-
to-common (starpoint) value.
f.
1-37 d-axis Inductance (Ld)
. Enter the line-to-common
direct axis inductance of the PM motor. If only line-to-line
data is available, divide the line-to-line value by two to get the
line-to-common (starpoint) value.
g.
1-38 q-axis Inductance (Lq)
. Enter the line-to-common
quadrature axis inductance of the PM motor. If only line-to-
line data is available, divide the line-to-line value
by two to get the line-to-common (starpoint) value.
h.
1-40 Back EMF at 1000 RPM
. Enter the 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 two 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
.

9.8 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
.
9.9 Testing the local control
1. Press
HAND ON
to provide a local start command to the
frequency converter.
2. Accelerate the frequency converter to full speed by pressing
[Up]. Moving the cursor left of the decimal point provides quicker
input changes.
3. Note any acceleration problems.
4. Press
OFF
. Note any deceleration problems.
9.10 Starting the system
The below steps require wiring and application programming to be
completed. We recommend that you follow this procedure after
application setup is completed.
1. Press
AUTO ON
.
2. Apply an external run command.
3. Adjust the speed reference throughout the speed range.
4. Remove the external run command.
5. Check the sound and vibration levels of the motor to ensure that
the system is working as intended. If warnings or alarms occur,
see the overview of warnings and alarms or refer to the service
instructions for the frequency converter.

9.11 Resetting to default settings
You can make a backup of the changed settings first by
uploading them to the operating panel.
9.11.1 Recommended reset
We recommend that you use
14-22 Operation Mode
to perform a
reset to default settings. In this way, some settings are kept, such
as operating hours, serial communication selections, personal
menu settings, fault log, alarm log and other monitoring functions.
1. Navigate to
14-** Special Functions
, and press
OK
.
2. Select
14-22 Operation Mode
, and press
OK
.
3. Use [Up] and [Down] to navigate to
[2] Initialisation
, and press
OK
.
4. Switch off the power to the unit, and wait for the display to
switch off.
5. Reconnect the power.
6. Alarm 80,
Drive initialised to default value
, is displayed.
7. Press
RESET
to return to operating mode.
9.11.2 Manual reset
You can also manually reset to default settings, but
this method deletes all motor-, programming-, localisation- and
monitoring data. It does not reset settings for
15-00 Operating
hours
,
15-03 Power Up’s
,
15-04 Over Temp’s
and
