2 Parameters
2.2 List of parameters
Dependency: Refer to: r0026
Notice: When measuring a DC link voltage < 200 V, for the Power Module a valid measured value is not supplied. In this
case, when an external 24 V power supply is connected, a value of approx. 24 V is displayed in the display
parameter.
Note: The DC link voltage is available smoothed (r0026) and unsmoothed (r0070).
r0071 Maximum output voltage / U_output max
Access level: 3
Can be changed: -
Unit group: 5_1
Min
- [Vrms]
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
voltage.
r0072 CO: Output voltage / U_output
Access level: 3
Can be changed: -
Unit group: 5_1
Min
- [Vrms]
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).
r0073 Maximum modulation depth / Modulat_depth max
Access level: 4
Can be changed: -
Unit group: -
Min
- [%]
Description: Displays the maximum modulation depth.
Dependency: Refer to: p1803
r0074 CO: Modulat_depth / Mod_depth
Access level: 4
Can be changed: -
Unit group: -
Min
- [%]
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).
