2 START-UP PREPARATION
DANGER!
Always disconnect the main power supply before making any connection.
1. Check if the power, grounding and control connections are correct and firm.
2. Remove all the materials left behind from the installation work from inside the inverter or the cabinet.
3. Verify the motor connections and if its voltage and current are within the inverter rated value.
4. Mechanically uncouple the motor from the load. If the motor cannot be uncoupled, make sure that any
speed direction (forward or reverse) will not result in personnel injury and/or equipment damage.
5. Close the inverter or cabinet covers.
6. Measure the power supply and verify if it is within the allowed range. Please, refer to the user's manual,
available for download on the website: www.weg.net.
7. Apply power to the input: close the input disconnecting switch.
8. Check the result of the first time power-up:

5 DEFAULT CONFIGURATION FOR SPEED REFERENCE AND COMMAND
The CFW300 is configured at the factory by setting its parameters so as to define the logical command and
the speed reference in both LOCAL and REMOTE operating modes. This default setting can be restored
by means of P204 for both motors 60Hz and 50Hz (P204 = 5 or 6).
In the LOCAL mode, the command and reference are directed to the HMI of the CFW300, allowing the
commands Run/Stop, JOG and Direction of Rotation of the motor. In addition to these commands, the
HMI keypad can also be used to select the LOCAL or REMOTE mode. The speed reference can be set in
P121 or by means of the and keys of the HMI in the monitoring mode.
In the REMOTE mode, the speed reference and command are directed to the product terminals; DI1 executes
Run/Stop and DI2 the Direction of Rotation. The reference is executed by analog input AI1 in this mode.

2 PREPARACIÓN Y ENERGIZACIÓN
¡PELIGRO!
Siempre desconecte la alimentación general, antes de efectuar cualquier conexión.
1. Verifique sí las conexiones de potencia, puesta a tierra y de control estén correctas y firmes.
2. Retire todos los restos de materiales del interior del convertidor o del accionamiento.
3. Verifique las conexiones del motor y sí la corriente y la tensión del motor estén de acuerdo con el convertidor.
4. Desacople mecánicamente el motor de la carga. Si el motor no puede ser desacoplado, tenga la certeza
de que el giro en cualquier dirección (sentido horario o antihorario) no causará daños a la máquina o
riesgo de accidentes.
5. Cierre las tapas del convertidor o accionamiento.
6. Realice la medición de la tensión de la red y verifique que esté dentro del rango permitido. Por favor,
consulte el manual del usuario, disponible para download en el sitio: www.weg.net.
7. Energice la entrada: cierre la seccionadora de entrada.
8. Verifique el éxito de la energización:
