3-PT Operation ON allows 3 point operation. OFF disables 3 point operation and the
values of parameters V/Hz 3-PT Volts and V/Hz 3-PT Frequency are ignored.
V/Hz 3-PT Volts The output voltage associated with the 3PT Frequency parameter.
V/Hz 3-PT Frequency The output frequency associated with the 3PT Volts
parameter.
Max Output Volts The maximum output voltage available to the motor from the
control. This is useful if the motor rated voltage is less than the input line
voltage. In some cases the Max Output Volts and the CTRL Base Frequency
parameter values can be adjusted to provide a wider constant torque or wider
constant horsepower speed range than is normally available.
