Dependency: Default setting PM260: 103 %.
Refer to: p0500
Note: p1803 = 100% is the overcontrol limit for space vector modulation (for an ideal drive converter without any switching
delay).
Description: Defines the maximum modulation depth.
Dependency: Refer to: p0500
Note: p1803 = 100% is the overcontrol limit for space vector modulation (for an ideal drive converter without any switching
delay).
Description: Sets the filter time constant of the DC link voltage used to calculate the modulation depth.
Description: Sets the filter time constant of the DC link voltage used to calculate the modulation depth.
Note: A higher filter time constant can help to dampen (attenuate) low-frequency oscillations of the DC link voltage.
Description: Displays the effective modulator mode.
Value: 1: Flat top modulation (FLB)
2: Space vector modulation (SVM)
9: Optimized pulse pattern
