p1802[0...n] Modulator mode / Modulator mode
PM250 Access level: 3

Can be changed: T
Units group: -

Description: Sets the modulator mode.
Value: 0:

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 (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.
p1803[0...n] Maximum modulation depth / Modulat depth max
PM230 Access level: 4
Can be changed: U, T
Units group: -
Min
20.0 [%]
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).
p1803[0...n] Maximum modulation depth / Modulat depth max
PM240 Access level: 3
Can be changed: U, T
Units group: -
Min
20.0 [%]
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).
p1803[0...n] Maximum modulation depth / Modulat depth max
PM250 Access level: 3
PM260
Can be changed: U, T
Units group: -
Min
20.0 [%]
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).
