2.5 Test Run
After the post-installation checklist has been completed, follow the instructions below to test
the inverter.
1 Turn on the power supply to the inverter. Ensure that the keypad display light is on.
2 Select the command source.
3 Set a frequency reference, and then check the following:
•
If V1 is selected as the frequency reference source, does the reference change
according to the input voltage at VR?
•
If V2 is selected as the frequency reference source, is the voltage/current selector
swit
ch (SW4) set to ‘voltage’, and does the reference change according to the input
voltage?
•
If I2 is selected as the frequency reference source, is the voltage/current selector
switch (SW4) set to ‘current’, and does the reference change according to the input
current?
4 Set the acceleration and deceleration time.
5 Start the motor and check the following:
•
Ensure that the motor rotates in the correct direction (refer to the note below).
•
Ensure that the motor accelerates and decelerates according to the set times, and
that the motor speed reaches the frequency reference.
Note
If the forward command (Fx) is on, the motor should rotate counterclockwise when viewed from
the load side of the motor. If the motor rotates in the reverse direction, switch the cables at the U
and V terminals.
