2.1.2 Voltage reference
P2.2.1.1 DC VOLTAGE REFERENCE ID1462
Voltage reference in percentage of Source Nom Voltage.
P2.2.1.2 DROOPING ID620
Voltage reference drooping. Used when parallel DC-DC converters are used.
P2.2.1.3 REACTIVE CURRENT REFERENCE SOURCE SELECTION ID1867
Voltage reference ramp rate in in percentage or in seconds.
P2.2.1.4 VOLTAGE REFERENCE AT START ID1864
This parameter is used to define how the voltage reference starting value is handled in a start. The
start will be smoother when the value is close to the actual source voltage.
0 = Reference
Starting voltage is a directly given reference P2.2.1.1 Voltage Reference.
1 = V Ref Start
Starting voltage is defined by parameter P2.2.1.5 Start Voltage Reference and ramped to actual
reference with set ramp rate.
2 = Measurement
Starting voltage is taken from measured voltage V1.12.11 Voltage Meas. ID1866. This monitoring
value can be written by analogue ID function or from fieldbus.
3 = 80 %
Drive will start as an initial guess of 80% of source voltage.
P2.2.1.5 START VOLTAGE REFERENCE ID1865
The voltage value that is used for the initial start voltage when P2.2.1.4 Voltage Reference At Start
is 1 / V Ref Start.
