Danfoss VLT Midi Drive FC-280P4K0 [22/136] Notice

Danfoss VLT Midi Drive FC-280PK75 [22/136] Notice
selections, fault log, alarm log, and other
monitoring functions.
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, Drive initialised to default value is shown.
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 in the listed order. Find the
information on the motor nameplate.
1. Parameter 1-20 Motor Power.
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.
6. Parameter 1-30 Stator Resistance (Rs).
7. Parameter 1-31 Rotor Resistance (Rr).
8. Parameter 1-33 Stator Leakage Reactance (X1).
9. Parameter 1-35 Main Reactance (Xh).
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
Adaption (AMA) [1] Enable Complete AMA or enter the
parameters manually.
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 datasheet.
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.
