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:
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.
Description:
DC link voltage used to determine the maximum possible output voltage.
