FIRST TIME POWER-UP AND
START-UP
This chapter describes how to:
- Check and prepare the inverter before power-up.
- Power-up the inverter and check the result.
- Set the inverter for the operation in the V/f mode based on the power
supply and motor information by using the Oriented Start-Up routine
and the Basic Application group.
NOTE!
For a detailed description of the V V W or Vector control modes and for other available functions,
please refer to the CFW-11 Software Manual.
5.1 PREPARE FOR START-UP
The inverter shall have been already installed according to the recommendations listed in Chapter 3 – Installation
and Connection. The following recommendations are applicable even if the application design is different from
the suggested control connections.
DANGER!
Always disconnect the main power supply before performing any inverter connection.
1) Check if power, grounding, and control connections are correct and firmly secured.
2) Remove from the inside of the inverter all installation material left behind.
3) Verify the motor connections and if the motor voltage and current is within the rated value of the inverter.
4) Mechanically uncouple the motor from the load:
If the motor cannot be uncoupled, make sure that the chosen direction of rotation (forward or reverse) will
not result in personnel injury and/or equipment damage.
5) Return the inverter covers.
6) Measure the power supply voltage and verify if it is within the range listed in chapter 8.
7) Apply power to the input:
Close the input disconnect switch.
8) Check the result of the first time power-up:
The keypad should display the standar monitoring mode (figure 4.3
(a)
) and the status LED should be steady
green.
