Description
Defines the reference value for the line-side converter reactive power
generation. Line-side converter can generate reactive power to the supply
network. This reference is written into line-side converter unit parameter
Q POWER REF2. For more information, see IGBT Supply Control Program 7.x
Firmware manual [3AFE68315735 (English)].
Example 1: When parameter 24.03 Q POWER REF2 SEL is set to PERCENT,
value 10000 of parameter 24.02 Q POWER REF2 equals to value 100% of
parameter 24.01 Q POWER REF (that is 100% of the converter nominal power
given in signal 04.06 CONV NOM POWER).
Example 2: When parameter 24.03 Q POWER REF2 SEL is set to kVAr, value
1000 of parameter 24.02 Q POWER REF2 equals to parameter 24.01 Q
POWER REF value calculated with the following equation: 100 · (1000 kVAr
divided by converter nominal power in kVAr)%.
Example 3: When parameter 24.03 Q POWER REF2 SEL is set to PHI, value
3000 of parameter 24.02 POWER REF2 equals approximately to parameter
24.01 Q POWER REF value calculated with the following equation:

Positive reference 30° denotes capacitive load.
Negative reference 30° denotes inductive load.
P = signal 01.09 POWER value
Parameter 24.03 values are converter to degrees by the line-side converter
application program: -3000 ... 30000
to -30° / 30°, since the range is limited to -3000/3000.
Reference value.
Defines the intermediate circuit DC voltage reference for the line-side
converter. This reference is written into line-side converter parameter 23.01 DC
VOLT REF. For more information, see IGBT Supply Control Program 7.x
Firmware manual [3AFE68315735 (English)].

Defines the ambient temperature for the Enhanced drive temperature
monitoring function.
Note: If ambient temperature exceeds 40 °C, the drive load capacity
decreases. See the derating instructions in the appropriate hardware manual.
