Value 2 - 100 poles
Function:
Sets the motor pole number.

2 2700 - 2880
4 1350 - 1450
6 700 - 960
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 figure 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 EMF at 1000 RPM
Range:
10 - 1000 V
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 Offset
Range:
0 - 65535 N/A
Function:
Enter the correct offset angle between the PM motor
and the index position (single-turn) of the attached
encoder / resolver. The value range of 0 - 65535
corresponds to 0 - 2 * pi (radians). Hint: After
drive start-up, apply DC-hold and enter the value
of par. 16-20 Motor Angle in this parameter.
This parameter is only active when par. 1-10 has
the value [1] PM motor (Permanent Magnet Motor).

Function:
Is used along with par. 1-51 to obtain a different
thermal load on the motor when running at low

MG.33.B3.22 - VLT is a registered Danfoss trademark
speed. Enter a value which is a percentage of the
rated magnetizing current. A setting too low may
cause a reduced torque on the crankshaft.
1-51 Min Speed Normal Magnetizing [RPM]
Range:
0 - 10 RPM
Function:
Is used along with par. 1-50. See drawing in
par. 1-50. Set the required frequency (for normal
magnetizing current). If the frequency is set
lower than the motor slip frequency, par. 1-50
and par. 1-51 are of no significance.
1-52 Min Speed Normal Magnetizing [Hz]
Range:
0 - 10 Hz
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
Function:
Flux Model shift
With this parameter it is possible to make an
adjustment of the shifting point where FC 302
changes the FLUX model. Useful in some sensitive
speed and torque control applications.
