Free-run stop [FRS]
•When the terminal [FRS] is turned on, the inverter stops the output and the motor enters the free-run state
(coasting).
If terminal [FRS] is turned off, theoutput resumes sending power to the motor if the Run command is still
active.
The free-run stop feature works with other parameters to provide flexibility in stopping and starting motor
rotation.
•In the figure below, parameterB16 selects whether the inverter resumes operation form 0Hz (left graph) or
the current motor rotation speed (right graph) when the [FRS] terminal turns off.
The application determines which is the best setting.
Parameter B03 specifies a delay time before resuming operation from a free-run stop.
To disable this feature, use a zero delay time.

FRS
Free-run Stop
ON
Causes output to turn off, allowing motor to
free run (coast) to stop
OFF
Output operates normally, so controlled deceleration
stops motor
Valid for inputs:
C01,C02,C03,C04,C05,C06
Example:
Required setting
B03, b16, C07 to C12
Notes:
•When you want the [FRS] terminal to be
active low(normally closed logic),
change the setting (C07 to C12) which
corresponds to the input (C01 to C06)
that is assigned the [FRS] function
