How to Program
Value 2 - 1 00 poles
*
4-polemotor
Function:
Sets the motor pole number.
Poles ~n
n
@50Hz ~n
n
@60 H z
2 2700 - 2880 3250 - 3460
4 1350 - 1450 1625 - 1730
6 700 - 960 840 - 1153
The table shows the normal speed range for
various motor types. Define motors designed
for other frequencies separately. The stated
value must be, even as the fig ure refers to the
motor’s number of poles (not a pair of poles). The
drive carries out the initial setting of par. 1-39
based on par. 1-23 and par. 1-25.
1-40 Back EM F at 1000 RPM
Range:
10 - 1000 V
*
500V
Function:
Set the nominal back EMF for the motor
running at 1000 RPM.
This parameter is only active when par. 1 -10 has
the value [1] PM motor (
Permanent Magnet Motor).
1-41 Motor Angle Of
fset
Range:
0 - 65 535 N/A
*
0N/A
Function:
Enter the correct offset angle between the PM motor
and the index position (single-turn) of the attached
encoder / resolve
r. Th e value range of 0 - 65535
corresponds to 0 - 2 * pi (radians). Hint: After
drive sta rt-up, a pply DC-hold and enter the value
of par. 16-20 Mo
tor Angle in this parameter.
This paramet
er is only active when par. 1-10 has
the value [1] PM motor (Permanent Magnet Motor).
" 1-5* Load Indep. Setting
1-50 Motor Magnetiz ati on at Zero Speed
Range:
0-300%
*
100%
Function:
Is used along with par. 1-51 to obtain a different
thermal load on the motor when running at low
speed. Enter a value which is a percentage of the
rated m agnetizing current. A setting too low may
cause a reduced torque on the crankshaft.
1-51 Min Speed Normal Magnetizing [RPM]
Range:
0-10RPM
*
1RPM
Function:
Is used along with par. 1-50. See drawing in
par. 1-50 . S et the required frequency (for normal
magnetizing current). If the frequency is set
lower than the motor slip frequency, par. 1-50
and p ar. 1-51 are of no significance.
1-52 Min Speed Normal Magnetiz in g [Hz]
Range:
0-10Hz
*
0Hz
Function:
Is used along with par. 1-50. See drawing
in par. 1-50. Set the required frequency (for
normal magnetising current). If the frequency
is set lower than the motor slip frequency, par.
1-50 and par. 1-51 are inactive.
1-53 Model Shift Frequency
Range:
4.0 - 50.0 Hz
*
6.7Hz
Function:
Flux Model shift
With this parameter it is possible to make an
adjustment of the shifting point where FC 302
changes the FLUX m o del. Useful in some sensitive
speed and torque control applications.
