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 off.
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 off.
2.
Press and hold [Status], [Main Menu], and [OK] at
the same time while applying power to the unit
(approximately 5 s or until audible click and 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
5.4 Basic Programming
5.4.1 Asynchronous Motor Set-up
Enter the following motor data. The information can be
found 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-specific 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.
5.4.2 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:
-
[1] PM, non salient SPM
-
[2] PM, salient IPM, non Sat
-
[3]PM, salient IPM, Sat
2.
Select
[0] Open Loop
in
parameter 1-00 Configu-
ration Mode
.
NOTICE
Encoder feedback is not supported for PM motors.
Programming motor data
After selecting PM motor 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.
The information can be found on the motor nameplate
and in the motor data sheet.
Programme 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)
.
