obtain the offset angle value: After frequency converter start-up apply DC-hold and enter the value
of par. 16-20
Motor Angle
into this parameter.
This parameter is only active when par. 1-10
Motor Construction
is set to
PM, non-salient SPM
[1]
(Permanent Magnet Motor).
3.3.5 1-5* Load Indep. Setting
Parameters for setting the load-independent motor settings.
1-50 Motor Magnetisation at Zero Speed
Range: Function:
100 %* [0 - 300 %] Use this parameter along with par. 1-51
Min Speed Normal Magnetising [RPM]
to obtain a different
thermal load on the motor when running at low speed.
Enter a value which is a percentage of the rated magnetizing current. If the setting is too low, the
torque on the motor shaft may be reduced.
1-51 Min Speed Normal Magnetising [RPM]
Range: Function:
Application
dependent*
[10 - 300 RPM] Set the required speed for normal magnetising current. If the speed is set lower than the motor slip
speed, par. 1-50
Motor Magnetisation at Zero Speed
and par. 1-51
Min Speed Normal Magnetising
[RPM]
are of no significance.
Use this parameter along with par. 1-50
Motor Magnetisation at Zero Speed
. See drawing for
par. 1-50
Motor Magnetisation at Zero Speed
.
1-52 Min Speed Normal Magnetising [Hz]
Range: Function:
Application
dependent*
[Application dependant] Set the required frequency for normal magnetising current. If the frequency is set lower than the
motor slip frequency, par. 1-50
Motor Magnetisation at Zero Speed
is inactive.
Use this parameter along with par. 1-50
Motor Magnetisation at Zero Speed
. See drawing for
par. 1-50
Motor Magnetisation at Zero Speed
.
1-53 Model Shift Frequency
Range: Function:
Application
dependent*
[Application dependant] Flux Model shift
Enter the frequency value for shift between two models for determining motor speed. Choose the
value based on settings in par. 1-00
Configuration Mode
and par. 1-01
Motor Control Principle
. There
are two options: shift between Flux model 1 and Flux model 2; or shift between Variable Current
mode and Flux model 2. This parameter is available for FC 302 only.
This parameter cannot be adjusted while the motor is running.
