 : Auto-stop in case of lower-limit frequency continuous operation
 : Hysteresis for LL stop operation
 : Restart deviation for LL stop operation
 : Restart feedback for LL stop operation
• Function
If operation is carried out continuously at a frequency command below the lower-limit frequency (  ) for
the period of time set with  , the inverter will automatically slow down the motor to a stop. At that
6
time, "  " is displayed (alternately) on the operation panel.
This function will be canceled if a frequency command above the lower-limit frequency (  )
+  Hz.
PID control selected-> The stop of this function will be canceled by deviation and feedback when
f392 and f393 is setting.
