execute the reset operation. If the inverter is

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.

•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).
