If
is set to
or
, the output voltage will change in proportion to the input voltage.
Even if the base frequency voltage (
) 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
to
prevents the output voltage from increasing, even if the input voltage changes when the operation
frequency exceeds the base frequency.
When the V/f control mode selection parameter (
