• 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
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.
