d6 Field Weakening
d6-01 Magnetic Field Weakening Level
Setting Range: 0 to 100 %
Factory Default: 80 %
The output voltage during magnetic field weakening operation is the product of the normal V/f settings (El-03 to E1-13) and
the magnetic field weakening level. The output voltage decreases and recovers in the voltage recovery time (L2-04). The level
is set as a percentage taking the voltage set in the V/f pattern as 100% The magnetic field weakening function is only enabled
when a multi-function input “field weakening command” is closed (H1-0x = 63).
d6-02 Magnetic Field Weakening Frequency
Setting Range: 0.0 to 400.0 Hz
Factory Default: 0.0 Hz
Sets the lower limit of the frequency range where field weakening control is valid. The field weakening command is valid only
at frequencies above this setting and only when output frequency is in agreement with the current output frequency (speed
agree).
d6-03 Magnetic Field Forcing Function Selection
Sets the magnetic field forcing function.
