Installing the Inverter
Note
STP (Shielded Twisted Pair) cable has a highly conductive, shielded screen around twisted cable pairs.
STP cables protect conductors from electromagnetic interference.
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 switch
(SW2) 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
(SW2) 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.
Verifying the Motor Rotation
1 On the keypad, set the drv (Frequency reference source) code in the Operation group to 0
(Keypad).
2 Set a frequency reference.
3 Press the [RUN] key. Motor starts forward operation.
4 Observe the motor’s rotation from the load side and ensure that the motor rotates
counterclockwise (forward).
