2 Parameters
2.2 List of parameters
Description: Sets the modulator mode.
Value: 0: Automatic changeover SVM/FLB
2: Space vector modulation (SVM)
3: SVM without overcontrol
4: SVM/FLB without overcontrol
10: SVM/FLB with modulation depth reduction
19: Optimized pulse pattern
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.
p1802 = 10 can only be set for power units PM230 and PM240 and for r0204.15 = 0.
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 = 98%). The higher the overmodulation, the greater the current 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.
Description: Sets the modulator mode.
Value: 0: Automatic changeover SVM/FLB

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.
