Rockwell Automation 7000A PowerFlex Medium Voltage AC Drive - Air-Cooled (A Frame) - Manual (Page 235)

Commissioning 4-81
7000 “A” Frame 7000A-RM001A-EN-P – January 2011
Summary:
• Drive input contactor should be closed. If the drive input
contactor configuration is set to NOT RUNNING, you will have
to temporarily change it to ALL FAULTS.
• Ensure that the drive is not running when capturing these
waveforms.
• Capture line voltage at ACB test point “V2uv” and line current
at ACB test point “I2u”.
• Label the waveforms as “V2uv”, and “I2u”.
• Save the worksheet as “Harmonics (Drive Not Running)”.
