• Function
If operation is carried out continuously at a frequency command below the lower-limit frequency (NN) for
the period of time set with H, the inverter will automatically slow down the motor to a stop. At that
time, “NUVR” is displayed (alternately) on the operation panel.
This function will be canceled if a frequency command above the lower-limit frequency (NN) +0.2Hz.
