Powerup Test
CAUTION: If you operate a motor at a frequency higher than the inverter standard
default setting (50Hz/60Hz), be sure to check the motor and machine specifications with
the respective manufacturer. Only operate the motor at elevated frequencies after getting
their approval. Otherwise, there is the danger of equipment damage.
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 correct?
• Did the inverter trip during acceleration or deceleration?
• Were the rpm and frequency meter readings as expected?
• Were there any abnormal motor vibrations or noise?
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
button. 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 the initialization
instructions on page 6–8.
