5.11.7.4.2. Power vs. Frequency
Gradient means the slope of power reduction, ie.
–xx%/Hz
Figure 5-44. Power vs. frequency setting page
5.11.7.4.3. Constant cosφ
When this Mode is turned on, inverter will maintain power factor as a constant value. Users
can set power factor from Cap 0.80 to Ind 0.80.
Figure 5-45.
Constant cosφ setting page
5.11.7.4.4. cosφ(P)
The inverter controls the output cosφ as a function of the power it injects into the utility mains
and
cosφ (P) control will not concern Grid voltage.
