Parameters
List of parameters
Dependency: Refer to: r0027
Notice: The value is updated with the current controller sampling time.
Note: Absolute current value = sqrt(Iq^2 + Id^2)
The absolute value of the current actual value is available smoothed (r0027 with 300 ms, r0068[1] with p0045) and
unsmoothed (r0068[0]).
r0069[0...6] CO: Phase current actual value / I_phase act value
Access level: 4
Can be changed: -
Units group: 6_5
Min
- [A]
Description: Displays 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
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: -
Units group: 5_2
Min
- [V]
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).
r0071 Maximum output voltage / U_output max
Access level: 3
Can be changed: -
Units 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 volt-
age.
