Powerup Test Section 2-4
!Caution Check the following before and during the Powerup test. Otherwise, there is
the danger of equipment damage.
• Is the shorting bar between the [+1] and [+] terminals installed? DO NOT
power or operate the inverter if the jumper is removed.
• Is the direction of the motor rotation correct?
• Did the inverter trip during acceleration or deceleration?
• Were the rpm and frequency meter readings as expected?
• Were there any abnormal motor vibration or noise?
2-4-3 Powering the Inverter
If you have followed all the steps, cautions and warnings up to this point,
you're ready to apply power. After doing so, the following events should occur:
•The POWER LED will illuminate.
• The numeric (7-segment) LEDs will display a test pattern, then stop at
0.0.
•The Hz LED will be ON.
If the motor starts running unexpectedly or any other problem occurs, press
the STOP key. Only if necessary should you remove power to the inverter as a
remedy.
Note If the inverter has been previously powered and programmed, the LEDs (other
than the POWER LED) may illuminate differently than as indicated above. If
necessary, you can initialize all parameters to the factory default settings. See
"Restoring Factory Default Settings" on page 245.
