Siemens SINAMICS G120X - Maximum Modulation Depth; Modulat Depth Max

p1802[0...n] Modulator mode / Modulator mode
G120X_DP (PM330),
G120X_PN (PM330),
G120X_USS (PM330)
Access level: 4 Calculated:
CALC_MOD_LIM_REF
Data type: Integer16
Can be changed: T Scaling: - Dynamic index: DDS, p0180
Unit group: - Unit selection: - Function diagram: -
Min:
0
Max:
19
Factory setting:
9
Description: Sets the modulator mode.
Value: 0: Automatic changeover SVM/FLB
2: Space vector modulation (SVM)
9: Edge modulation
19: Optimized pulse pattern
Dependency: Setting p1802 = 19 (optimized pulse pattern) is only released for chassis/built-in power units and SIMOTICS FD
motors up to a maximum speed of p1082 <= 60 x 100 Hz / r0313.

NOTICE
When modulation modes are enabled that could lead to overmodulation (p1802 = 0, 2), 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.
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
Access level: 3 Calculated:
CALC_MOD_LIM_REF
Data type: FloatingPoint32
Can be changed: T, U Scaling: - Dynamic index: DDS, p0180
Unit group: - Unit selection: - Function diagram: 6723
Min:
20.0 [%]
Max:
150.0 [%]
Factory setting:
106.0 [%]
Description: Defines the maximum modulation depth.
Dependency: See also: p0500
Note
p1803 = 100% is the overcontrol limit for space vector modulation (for an ideal drive converter without any switching
delay).
