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.

18 RS Reset Inverter ON The motor output is turned OFF, the Trip Mode
is cleared (if it exists), and powerup reset is
applied

Valid for inputs:
C001, C002, C003, C004,
C005
Required settings:
(none)
Notes:
•
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.
• Pressing the Stop/Reset key of the digital operator can generate a reset operation only when an alarm
occurs.
• A terminal configured with the [RS] function can only be configured for normally open operation. 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.
• The Stop/Reset key on the inverter is only operational for a few seconds after inverter powerup when a
hand-held remote operator is connected to the inverter.
• If the [RS] terminal is turned ON while the motor is running, the motor will be free running (coasting).
• If you are using the output terminal OFF delay feature (any of C145, C147, C149 > 0.0 sec.), the [RS]
terminal affects the ON-to-OFF transition slightly. Normally (without using OFF delays), the [RS]
input causes the motor output and the logic outputs to turn OFF together, immediately. However, when
any output uses an OFF delay, then after the [RS] input turns ON, that output will remain ON for an
additional 1 sec. period (approximate) before turning OFF.
