2.5 Test Run
1.
After the post-installation checklist has been completed, follow the instructions below to test the
inverter.
2.
Turn on the power supply to the inverter. Ensure that the keypad display light is on.
3.
Choose to Run Quick Start?
4.
Select the command source.
5.
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 switch (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?
6.
Set the acceleration and deceleration time.
7.
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.
Check the parameter settings before running the inverter. Parameter settings may have
to be adjusted depending on the load.
To avoid damaging the inverter, do not supply the inverter with an input voltage that
exceeds the rated voltage for the equipment.
Before running the motor at maximum speed, confirm the motor’s rated capacity. As
inverters can be used to easily increase motor speed, use caution to ensure that motor
speeds do not accidently exceed the motor’s rated capacity.
Verifying the Motor Rotation
1 On the keypad, set DRV-07 to ‘1 (Keypad)’.
2 Set a frequency reference.
3 If the inverter is in OFF mode, press the [AUTO] button twice on the keypad to
operate the inverter in the forward (Fx) direction.
4 If the inverter is operating in AUTO mode, press the [AUTO] button once on the
keypad to operate the inverter in the forward (Fx) direction.
5 Observe the motor’s rotation from the load side and ensure that the motor rotates
Counterclockwise.
