CHAPTER 5
5.1 PRE-POWER
CHECKS
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 (See Electrical Installation).
The inverter shall be installed according to Chapter 3 - Installation
and Connection. If the drive project is different from the typical
suggested connections, follow the procedures below.
DANGER!
Always disconnect theAC 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.
3) 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.
5.2 INITIAL
POWER-UP
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: - 15 % / + 10 %).
2) Power-up the AC input
Close the input circuit breaker.
3) Check if the power-up has been succesful
The keypad display will show:
While the red LED (Parameter) is ON, the green LED (Value) remains
OFF. Inverter runs some self-diagnosis routines. If no problems are
found, the display shows:
START-UP
This means that the inverter is ready (rdy = ready) to be operated.
