START-UP
This Chapter provides the following information:
how to check and prepare the inverter before power-up;
how to power-up and check for proper operation;
how to operate the inverter when it is installed according to the typical
connections (refer to Section 3.2 - Electrical Installation).
The inverter shall be installed according to Chpater 3 - Installation and
Connection. If the drive project is different from the typical suggested
connections, follow the procedures below.
DANGER!
Alaways disconnect the AC input power before making any connections.
1) Check all connections
Check if the power, grounding and control connections are correct
and well tightened.
2) Check the motor
Check all motor connections and verify if its voltage, current and
frequency match the inverter specifications.
4) Uncouple the load from the motor
If the motor can not be uncoupled, make sure that the direction of
rotation (FWD/REV) can not cause damage to the machine.
After the inverter has been checked, AC power can be applied:
1) Check the power supply
Measure the line voltage and check if it is within the specified range
(rated voltage: + 10% / - 15%).
2) Power-up the AC input
Close the input circuit breaker or disconnect switch.
3) Check if the power-up has been succesful
- Inverter with keypad (HMI-CFW08-P or HMI-CFW08-RS)
The keypad display will show:
The four LEDs of the keypad remains ON during this procedure.
Inverter runs some self-diagnosis routines. If no problems are found, the
display shows:
This means that the inverter is ready (rdy = ready) to be operated.
- Inverter with dummy panel (TCL-CFW08 or TCR-CFW08).
The LEDs ON (green) and ERROR (red) are ON.
Inverter runs some self-diagnosis routines. If no problems are found the
LED ERROR (red) turns OFF. This means that the inverter is now ready
to be operated.
