Description:
Display and connector output for the measured actual phase currents as peak value.
Index:
[0] = Phase U
[1] = Phase V
[2] = Phase W
[3] = Phase U offset
[4] = Phase V offset
[5] = Phase W offset
[6] = Total U, V, W
[7] = Alpha component
[8] = Beta component
Note
In indices 3 ... 5, the offset currents of the 3 phases, which are added to correct the phase currents, are displayed.
The sum of the 3 corrected phase currents is displayed in index 6.
r0070
CO: Actual DC link voltage / Vdc act val
Access level: 3
Can be changed: -
Unit group: 5_2
Min:
- [V]
Description:
Display and connector output for the measured actual value of the DC link voltage.
Dependency:
See also: r0026
NOTICE
When measuring a DC link voltage < 200 V, for the Power Module (e.g. PM240) 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 / Voltage 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.
