Reset Inverter
The [RS] terminal causes the inverter to
execute the reset operation. If the inverter is
in Trip Mode, the reset cancels the Trip
state. When the signal [RS] is turned ON
and OFF, the inverter executes the reset
operation. The minimum pulse width for
[RS] must be 12 ms or greater. The alarm
output will be cleared within 30 ms after the
onset of the Reset command.

WARNING: After the Reset command is given and the alarm reset occurs, the motor will
restart suddenly if the Run command is already active. Be sure to set the alarm reset after
verifying that the Run command is OFF to prevent injury to personnel.

Notes:
• When the control terminal [RS] input is
• When the control terminal [RS] input is
already ON at powerup for more than 4
seconds, the remote operator display is “R-
ERROR COMM<2>” (the display of the
digital operator is – – – –). However, the
inverter has no error. To clear the digital
operator error, turn OFF the terminal [RS]
input and press one of the operator keys.
seconds, the remote operator display is “R-
ERROR COMM<2>” (the display of the
digital operator is – – – –). However, the
inverter has no error. To clear the digital
operator error, turn OFF the terminal [RS]
input and press one of the operator keys.
• The active edge (leading or trailing) of the [RS] signal is determined by the setting of
C102.
• A terminal configured with the [RS] function can only be configured as a normally open
contact. The terminal cannot be used in the normally closed contact state.
• When input power is turned ON, the inverter performs the same reset operation as it does
when a pulse on the [RS] terminal occurs.
