2.4 Test Run
After the post-installation checklist has been completed, follow the instructions below to test the
inverter.
1 Before starting a test drive, check the wiring conditions.
2 Turn on the power supply to the inverter. Ensure that the keypad display light is on.
3 Select the command source
(Set the DRV code).
4 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?
5 Set the acceleration (ACC) time and deceleration (Dec) time.
6 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.
