Manual initialization erases all motor,
programming, localization, and monitoring data
and restores factory default settings.
Recommended initialization procedure, via
parameter 14-22 Operation Mode
1. Press [Main Menu] twice to access parameters.
2. Scroll to parameter 14-22 Operation Mode and
press [OK].
3. Scroll to [2] Initialisation and press [OK].
4. Remove power to the unit and wait for the
display to turn o.
5. Apply power to the unit.
Default parameter settings are restored during start-up.
This may take slightly longer than normal.
6. Alarm 80 is displayed.
7. Press [Reset] to return to operation mode.
Manual initialization procedure
1. Remove power to the unit and wait for the
display to turn
o.
2. Press and hold [Status], [Main Menu], and [OK] at
the same time while applying power to the unit
(approximately 5 s or until a click is heard and
the fan starts).
Factory default parameter settings are restored during
start-up. This may take slightly longer than normal.
Manual initialization does not reset the following
frequency converter information:
•
Parameter 15-00 Operating hours
•
Parameter 15-03 Power Up's
•
Parameter 15-04 Over Temp's
•
Parameter 15-05 Over Volt's

Basic Programming
3.2.1 Asynchronous Motor Set-up
Enter the following motor data. Find the information on
the motor nameplate.
1. Parameter 1-20 Motor Power [kW].
2. Parameter 1-22 Motor Voltage.
3. Parameter 1-23 Motor Frequency.
4. Parameter 1-24 Motor Current.
5. Parameter 1-25 Motor Nominal Speed.
For optimum performance in VVC
+
mode, extra motor data
is required to set up the following parameters. The data is
found in the motor datasheet (this data is typically not
available on the motor nameplate). Run a complete AMA
using parameter 1-29 Automatic Motor Adaptation (AMA) [1]
Enable Complete AMA or enter the parameters manually.
1. Parameter 1-30 Stator Resistance (Rs).
2. Parameter 1-31 Rotor Resistance (Rr).
3. Parameter 1-33 Stator Leakage Reactance (X1).
4. Parameter 1-35 Main Reactance (Xh).
Application-specic adjustment when running VVC
+
VVC
+
is the most robust control mode. In most situations,
it provides optimum performance without further
adjustments. Run a complete AMA for best performance.
3.2.2
PM Motor Set-up in VVC
+
Initial programming steps
1. Set parameter 1-10 Motor Construction to the
following options to activate PM motor operation:
1a [1] PM, non salient SPM
1b [2] PM, salient IPM, non Sat
1c [3] PM, salient IPM, Sat
2. Select [0] Open Loop in parameter 1-00 Congu-
ration Mode.
NOTICE
Encoder feedback is not supported for PM motors.
Programming motor data
After selecting 1 of the PM motor options in
parameter 1-10 Motor Construction, the PM motor-related
parameters in parameter groups 1-2* Motor Data, 1-3* Adv.
Motor Data, and 1-4* Adv. Motor Data II are active.
Find the information on the motor nameplate and in the
motor data sheet.
Program the following parameters in the listed order:
1. Parameter 1-24 Motor Current.
2. Parameter 1-26 Motor Cont. Rated Torque.
3. Parameter 1-25 Motor Nominal Speed.
4. Parameter 1-39 Motor Poles.
5. Parameter 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-to-
common (starpoint) value.
It is also possible to measure the value with an
ohmmeter, which also takes the resistance of the
cable into account. Divide the measured value by
2 and enter the result.
6. Parameter 1-37 d-axis Inductance (Ld).
