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
24.02 Q POWER REF2. For more information, see IGBT Supply
Control Program 7.x Firmware manual [3AFE68315735 (English)].
Example 1: When 24.03 Q POWER REF2 SEL is set to PERCENT,
value 10000 of 24.02 Q POWER REF2 equals to value 100% of 24.01
Q POWER REF (i.e. 100% of the converter nominal power given in
04.06 CONV NOM POWER).
Example 2: When 24.03 Q POWER REF2 SEL is set to kVAr, value
1000 of 24.02 Q POWER REF2 equals to 24.01 Q POWER REF value
calculated with the following equation: 100 · (1000 kVAr divided by
converter nominal power in kVAr)%.
Example 3: When 24.03 Q POWER REF2 SEL is set to PHI, value
3000 of 24.02 POWER REF2 equals approximately to 24.01 Q
POWER REF value calculated with the following equation:

P = signal 01.09 POWER value
24.03 Q POWER REF2 SEL values are converted to degrees by the
line-side converter control program: -3000...30000 -30°...30°. Value -
10000/10000 equals 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 23.01 DC
VOLT REF. For more information, see IGBT Supply Control Program
7.x Firmware manual [3AFE68315735 (English)].

Selects the line-side converter address from which
SIGNAL 1 is read.
Line-side converter parameter index.
Selects the line-side converter address from which
SIGNAL 2 is read.
Line-side converter parameter index.
Defines the ambient temperature for the Enhanced drive temperature
monitoring function. See Enhanced drive temperature monitoring for
ACS800-U2, -U4 and -U7, frame sizes R7 and R8
Note: If ambient temperature exceeds 40
decreases. See derating instructions in the appropriate hardware
manual.
