F57: Percentage in energy saving running
output voltatge (V)
100%
75%
This parameter is for minimum output voltage percentage in energy saving
running For constant torque running, inverter can calculate the optimized
output voltage to the load according to the load state. Calculation is invalid
during acceleration or deceleration. This function is to save energy by lower
the output voltage and enhance the frequency factors, this parameter
confirms the minimum reduced output voltage; if the parameter is set 100%,
the energy saving running mode is closed.
If energy saving is effective, inverter's actual voltage output value=inverter's
rated output voltage × output voltage percentage × energy saving output
voltage percentage.

When output signal select(o13-o17) 14, inverter's output frequency
arrives or accesses FDT frequency set 1, output signal terminal actions;
inverter's output frequency is lower than the set frequency, output signal
does not action.
When output signal select(o13-o17) 15，firstly FDT frequency set 1
inspected, inverter's output frequency arrives or accesses FDT frequency

Section VI. Function Parameter Description
set 1, output signal terminal actions; after terminal action, FDT frequency
set 2 inspected, inverter's output frequency is lower than FDT frequency
set 2, output signal terminal does not action.
e.g. FDT frequency set 1 is 35Hz, FDT frequency set 2 is 30Hz, output
signal terminal actions as above:
F60: Frequency inspection range
This parameter defines frequency inspection range for adjusting I/O output
function: 11 set frequency reaching the inspection range.
F61: Load type
The parameter defines the load type, the system automatically adjust the
parameters according to the load type to satisfy different requirement of
different load. Please inquir Powtran technician to select the right load type.
Wrong load type may damage the equipment.
