Description: Sets the monitoring time for the current-offset measurement of the power unit.
The time is started with the normal end of the measurement. If the measurement is invalid and if no valid measure-
ment can be taken within the monitoring period (phase currents too high), an appropriate message is generated.
Note: Set this parameter to 0 to allow variations in the delay when running-up.
Description: Sets the delay time for shutdown due to a line supply undervoltage condition (A06100).
After the fault occurs, the power unit is only tripped (shut down) after this delay has expired. If the fault is removed
during this design time, then the power unit is not tripped (shut down).
Dependency: Refer to: p0283
Refer to: F06100
Note: The degree of ruggedness of the infeed with respect to fluctuations in the line supply voltage can be increased by
parameterizing this delay value.
However, the following should be noted:
- the infeed power decreases proportionally (linearly) with the line supply voltage.
- when other components are connected, for low line supply voltage, operating faults or damage can occur. In this
case, the specifications of the connected electrical components should always be carefully observed.
Description: Displays the maximum permissible step-up factor for the power unit used in conjunction with the line filter parame-
terized in p0220[0].
Dependency: Refer to: p0210, p3510
Note: The maximum step-up factor determines the maximum ratio between the DC link voltage setpoint (p3510) and the
unit supply voltage (p0210).
The input of the DC link voltage setpoint (p3510) is limited corresponding to the permissible step-up factor (r3508).
