4-2 Function Mode •For instructions on how to switch on/off this function automatically with an arbitrary frequency, refer to "2-step Acceleration/Deceleration Function" (page 4-24). •To switch via a multi-function input, allocate 09 (2CH) to it.

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 pull-in restart). (Examples 1, 2) •The setting of this function is also applied to stop selection b091.
