E-33 Free stop frequency Range ：0.00～60.0Hz Factory
setting：0.50Hz
While the frequency inverter receives the stop order in the deceleration stop
mode, it will decelerate to the free stop frequency according to the
deceleration time, then stops output and the motor free stops.
Tips: This function is valid only while stop , invalid in the process of FOR/REV
switching.
0：Deceleration stop According to the setting time and deceleration mode,
frequency inverter will stop output frequency and close down motor after the
frequency inverter decelerate to the free stop frequency.
During the deceleration stop process, when the given frequency is smaller
than the DC braking initial frequency（please refer to ［E-37］）, if the close
down DC braking function is seleced, the output frequency of frequency inverter
will jump to zero, and the frequency inverter will stop work after the DC braking
finished. Otherwise, the frequency inverter will decelerate to free stop
frequency, and stop work. While stop,if the setting value of the DC braking
initial frequency［E-37］smaller than the setting value of the free stop
frequency, after decelerate to free stop frequency, frequency inverter will
stop output and will not carry on the DC braking.
During the process of decelerating stop, the machines with built-in braking
unit（below 15G/18.5P）can connect with the external braking resistor(optional).
If the DC bus voltage exceeds the ［E-53 ］energy-consumed braking action
voltage value, frequency inverter will output the pulse voltage by setting
energy-consumed braking ration［E-54］; The machines without built-in braking
