Notes:
inverter may start the motor with 0 Hz if:
• the motor speed is no more than half of the base frequency, or
• the voltage induced on the motor is attenuated quickly.
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.
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.
