operation
H : Auto-stop in case of lower-limit frequency continuous operation
• Function
If operation is carried out continuously at a frequency 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).
