SINAMICS G120 / Control Units CU240B/E-2 Parameter Manual (LH11), 01/2011
Description: Displays the measured actual value of the DC link voltage.
Dependency: Refer to: r0026
Notice: When measuring a DC link voltage < 200 V, for the Power Module (e.g. PM240) a valid measured value is not sup-
plied. In this case, when an external 24 V power supply is connected, a value of approx. 24 V is displayed in the dis-
play parameter.
Note: The DC link voltage is available smoothed (r0026) and unsmoothed (r0070).
Description: Displays the maximum output voltage.
Dependency: The maximum output voltage depends on the actual DC link voltage (r0070) and the maximum modulation depth
(p1803).
Note: As the (driven) motor load increases, the maximum output voltage drops as a result of the reduction in DC link volt-
age.
Description: Displays 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
