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.

• 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).

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.
