Func
tions
Allocate 11 (FRS) to the desired multi-function input.
•This function is effective when you stop the motor using the mechanical brake such as an
electromagnetic one. Note that an overcurrent trip may occur if the mechanical brake forces the
motor to stop during Inverter output.
•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
Active Frequency Matching restart). (Examples 1, 2)
•The setting of this function is also applied to stop selection b091.
Main Unit Monitor Display Selection
You can select what items to display on the monitor when the ModBus communication or the Digital
Operator is connected with the communications connector on the Inverter.
•Enabled when the power is turned on, if:
C070 is set to "02" (Digital Operator), mode selector S7 to "OPE" (Digital Operator), and 3G3AX-
OP01 is connected;
C070 is set to "03" (ModBus), mode selector S7 to "485" (RS485 ModBus), and ModBus
communication is available.
•With this function enabled, keys other than the STOP/RESET key, and the FREQ adjuster on the
Digital Operator are disabled.
•In case of a trip, any trip code from "E01" to "E60" is displayed.
Also refer to "Output Frequency Monitor (After Conversion) [d007]" (page 4-3).

Free-run stop
ON
Sets the motor to free-run status by shutting off
output.
OFF
The motor is in normal operation.

C001 to C005
(Example 1) 0 Hz start
• Starts at 0 Hz regardless of motor rotation
speed. The retry wait time is ignored.
• An overcurrent trip may occur with this start at
a high motor speed.
(Example 2) Active Frequency Matching restart
• After the FRS terminal is turned off, the motor
frequency is matched and a Active Frequency
Matching restart is performed without stopping
the motor. If an overcurrent trip occurs, extend
the retry wait time.
