Start frequency
This frequency is the value the operator must set before the Inverter will give
an output.
Mainly used when an operator adjusts the start torque.
By setting the start frequency higher, direct starting is caused and the starting current increases. Therefore an
overload is within the restriction range and the inverter has a tendency to trip on over-current protection.

Units : Hz
Reduced voltage start selection
This function is to raise the voltage slowly on motor starting.
The lower this value the more torque is available on starting.
However, by making this value lower, the inverter has a tendency of tripping on
over-current protection, because of almost direct starting.
