6.8 Time limit for lower-limit frequency operation
 : Time limit for lower-limit frequency operation
 : Hysteresis for lower-limit frequency operation
 Function
If operation is carried out continuously at a frequency 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 time,
“” is displayed (alternately) on the operation panel.
This function will be canceled if a frequency command above the lower-limit frequency () 
(Hz).
