ALARM RESET input
When an alarm is generated, in most cases it will be automatically reset by an
appropriate protective function of the inverter.
Set the RUN/STAND-BY switch to the STAND-BY side, or also set the X0
(RUN/STOP) input to the STOP side if external input control is used. Then, after
confirming that the motor has stopped completely, turn the ALARM RESET input
ON for at least 20 ms.
Input an alarm reset signal, and once the alarm has been reset, turn the ALARM
RESET input OFF.

alarm. Continuing to operate the motor without removing the cause of
the alarm may damage the motor.
The ALARM RESET input is enabled only while the motor is stopped.

Using a controller with a built-in clamp diode
When a controller with a built-in clamp diode is used, a sneak current path may
sometime cause the motor to run even though the controller power is off, if the
inverter power is on. The motor may also run when the controller power and inverter
power are turned on/off simultaneously, because the power capacity of the controller
is different from that of the inverter.
When turning on the power, turn on the controller power first, and then turn on the
inverter power. When turning off the power, turn off the inverter power first, and
then turn off the controller power.
