Dependency: If a sine-wave filter is parameterized as output filter (p0230 = 3, 4), then only space vector modulation without
overcontrol can be selected as modulation type (p1802 = 3). This does not apply to power units PM260.
Refer to: p0230, p0500
Note: When modulation modes are enabled that could lead to overmodulation (p1802 = 0, 2, 10), the modulation depth
must be limited using p1803 (default, p1803 < 100 %). The higher the overmodulation, the greater the current ripple
and torque ripple.
When changing p1802[x], the values for all of the other existing indices are also changed.
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: 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: Defines the maximum modulation depth.
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: Sets the filter time constant for the DC link voltage.
This time constant is used to calculate the modulation depth.
