6.5.8.8 Freq-Watt
This setting is used to control real power based on the frequency excursion
This setting is applicable when Rule21 Standards are selected.
This function is for maintenance personnel only, wrong operation
will prevent the inverter from reaching maximum power.
Figure 6.42 Freq-Watt (1)
Start Freq: 60.50Hz
WGradient: 040%
Start Freq: This is the frequency that active power reduction starts.
WGradient: This is the active power reduction rate in terms of the frequency.
Stop Freq: This is the frequency that stops the correction cycle.
Hysteresis: This indicates whether hysteresis is enabled.
