React. P. Mode
for activating / deactivating reactive power mode
Selection options C. cosφ / C. Qrel / C. Qabs / cosφ/P / Q/U / Q/P / OFF
C. cosφ Constant cos phi specification
C. Qrel Constant specification of the relative reactive power in %
C. Qabs Constant specification of absolute reactive power in VAr
cosφ/P Cos phi specification depending on effective power
Q/U Relative reactive power specification depending on current grid
voltage
Q/P Relative reactive power specification depending on effective
power
OFF Reactive power mode deactivated
- first select one of the reactive power modes from the selection options
- then set the parameters in the relevant reactive power mode
The reactive power modes:
Const. Cosφ Constant cos phi specification
Once "Enter" has been pressed, the value for the cos φ power
factor can be set:
-0.85 (ind.) - +0.85 (cap.) -- Galvo
-0.70 (ind.) - +0.70 (cap.) -- Symo S, Symo M 8k2,
Symo Hybrid, Primo 8k2, Primo US 8k2
-0.00 (ind.) - +0.00 (cap.) -- Symo M 20, Primo 15, Eco, Symo
US 12, Symo US 24, Symo US (Eco)
Const. Cosφ TimeC. Time constant at which a new set value of the power factor cos
φ is activated
Const. Q Rel. Constant specification of the relative reactive power in %
Once "Enter" has been pressed, the value for the reactive pow-
er relative to the nominal apparent power can be set.
Const. Q Rel. TimeC. Time constant at which a new set value of the relative reactive
power is activated
Const. Q Abs. Constant specification of absolute reactive power in VAr
Once "Enter" has been pressed, the value for absolute reactive
power can be set from 0 to the max. device output (inductive/
capacitive) in VAr.
Const. Q Abs. TimeC. Time constant at which a new set value of the absolute reactive
power is activated
Ch Cosφ (P) *-* Cosφ (P) characteristic:
Cos phi specification depending on effective power
0-0 / 0-1 / 1-0 / 1-1 / 2-0 / 2-1 / 3-0 / 3-1 respectively
