, If H is set to "" or "", the output voltage will change in proportion to the input voltage.
, Even if the base frequency voltage (XNX parameter ) is set above the input voltage, the output voltage
will not exceed the input voltage.
, The rate of voltage to frequency can be adjusted according to the rated motor capacity. For example,
setting H to "" or "" prevents the output voltage from increasing, even if the input voltage
changes when operation frequency exceeds the base frequency.
, When the V/F control mode selection parameter (RV) is set to any number between and , the supply
voltage is corrected regardless of the setting of H.
