START-UP
For a safe start-up of the CTW900, it is really important to observe the instructions of this chapter.
Before, however, the converter must have already been installed according to the previous chapter.
NOTE!
Even if the drive project is different from the typical drives suggested, the steps below must also
be followed.
6.1
PREPARATION AND POWER-UP OF THE ELECTRONICS
Before energizing the power supply of the CTW900 (R/S/T), it is advisable to perform the following steps.
1.
Check if the power, grounding and control connections are correct and firm.
2.
Remove all materials left from the inside of the converter or drive.
3.
Check if the motor current and voltage match the converter.
4.
Mechanically uncouple the motor from the load. If the motor cannot be uncoupled, make sure that the
spinning in any direction will not cause damages to the machine and that no risks of accident are
present.
5.
Close the converter or drive covers.
6.
Measure the line voltage and check that it is within the permitted range, according to the CTW900
model.
7.
Energize the electronics (XC5) and confirm the success of the power-up: the display must show the
standard monitoring screen (Figure 6.1 a)) and the status LED must turn on and remain on in green.
8.
Finally, check the correct operation of the fans of the product (exhaustion of the internal air).
6.2
CONFIGURATION OF THE APPLICATION PARAMETERS
Once the electronics is powered up and no faults are present, the application parameters must be set.
That can be easily performed on the CTW900 by using the easy programming feature with the
Oriented Start-
Up
and
Basic Application
parameters.
In order to use this form of parameterization, just follow the sequence below:
1.
Insert the password for parameter modification;
2.
Execute the
Oriented Start-up
routine;
3.
Set the parameters of the
Basic Application
group.
ATTENTION!
The configuration of the application parameters is essential for the proper operation of the product,
since the conversion of some readings performed by the CTW900 is based on the values defined
by those parameters.
