2.2 List of parameters
Description: Display and connector output for the actual output voltage of the power unit.
Dependency: Refer to: r0025
Note: The output voltage is available smoothed (r0025) and unsmoothed (r0072).
Description: Displays the maximum modulation depth.
Dependency: Refer to: p1803
Description: Display and connector output for the actual modulation depth.
Dependency: Refer to: r0028
Note: For space vector modulation, 100% corresponds to the maximum output voltage without overcontrol.
Values above 100 % indicate an overcontrol condition - values below 100% have no overcontrol.
The phase voltage (phase-to-phase, rms) is calculated as follows:(r0074 x r0070) / (sqrt(2) x 100 %).
The modulation depth is available smoothed (r0028) and unsmoothed (r0074).
Description: Display and connector output for the field-generating current setpoint (Id_set).
Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
Note: This value is irrelevant for the U/f control mode.
