Dependency: If a sine-wave filter is parameterized as output filter (p0230 = 3, 4), then only space vector modulation without over-
control can be selected as modulation type (p1802 = 3). This is not valid for the power units PM260. p1802 = 10 can
only be set for the PM230 and PM240 power units.
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 (pre-assignment, p1803 = 98%). The higher the overmodulation, the greater the cur-
rent ripple and torque ripple. With p1802 = 10, the modulation depth limit is automatically reduced to 100% in the
critical output frequency range (over approx. 57 Hz).
When changing p1802[x], the values for all of the other existing indices are also changed.

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.
