5.5.2 Start-Up
Prerequisite:
These instructions assume that the variable frequency drive has its default
settings at the beginning of the commissioning process.
▶
Make sure that the motor is connected correctly and will not pose any
hazards when running.
The motor must have a load during the commissioning process so that it
will be possible to determine the right values.
▶
Enter the password in P-14 (default setting: 101) in order to allow access
to “parameter level 2.”
▶
Set the values for the
rated motor operating voltage
(P-07) and
rated
motor operational current
(P-08) parameters to the values on the
motor nameplate.
5.5.2.1 V-Boost (P-11)
▶
Set the
t-Boost
(P-33) parameter to the maximum possible value
(150.0 s). This will allow the voltage to increase slowly and make it
possible to easily adjust the start voltage and the startup behavior.
▶
Start the drive. Press the
OK
button as many times as necessary until
the current, “A…xxx”, is displayed.
The current should increase quickly, stabilize after a few seconds, and
then start increasing slowly. Monitor the current’s value for approx. 3 to
5 seconds after starting.
•
If the current is
less than 80 %
of the rated motor current:
▶
Switch off the drive.
▶
Increase the value in P-11.
▶
Repeat the test.
•
If the current is
greater than 90 %
of the rated motor current:
▶
Switch off the drive.
▶
Reduce the value in P-11.
▶
Repeat the test.
When P-11 is set correctly, the current should be 80 to 90 % of the rated
motor current for 3 to 5 seconds after starting.
￫
It is possible for the motor not to rotate during the adjustment
procedure. You can safely ignore this, as the procedure is used
only to determine the correct value for
V-Boost
(P-11).
