Func
tions
• Note that an overcurrent trip may occur if the mechanical brake forces the motor to stop during
Inverter output.
• Allocate 11 (FRS) to the desired multi-function input.
• Performs a free-run stop (FRS) while the FRS terminal is turned on.
When the FRS terminal is turned off, the motor restarts after retry wait time b003 elapses.
With RUN command selection A002 set to 01 (control terminal), the motor restarts only if the FW
terminal is turned on, even in free running.
• You can select the Inverter output mode for restart at free-run stop selection b088 (0 Hz start or
frequency matching restart). (Examples 1, 2)
• The setting of this function is also applied to stop selection b091.
Cooling Fan Control
• You can set whether to operate the Inverter's cooling fan constantly or only during Inverter
operation.
This function applies to the Inverter models with a built-in cooling fan.

Frequency matching start
· The Inverter starts running at 0 Hz regardless of the
motor rotation speed.
· The retry wait time is ignored at 0 Hz start.
· If the Inverter starts running at 0 Hz with the motor
rotation speed high, an overcurrent trip may occur.
· After the FRS terminal is turned off, the motor frequency
is matched and a frequency matching starts without stopping
the motor. If this causes an overcurrent trip, extend the retry
wait time.
