Rockwell Automation 7000A PowerFlex Medium Voltage AC Drive - Air-Cooled (A Frame) - Manual (Page 234)

4-80 Commissioning
7000A-RM001A-EN-P – January 2011 7000 “A” Frame
Sample waveforms captured on ACB test points showing 20 deg Phase Shift
between Master and two Slave Bridges
[Ch1-Master: V2uv (red), Ch2-Slave 1: V3uv (blue), Ch3-Slave 2: V4uv (green)]
Measure the harmonic (resonance) levels at the input to the drive.
NOTE: If you notice considerable distortion in the waveforms then
you MUST send those waveforms to MV Support via e-mail at
[email protected] and then call at 519-740-4790
(option 1) to discuss the issue and action plan. During after-hours, you
can call MV Support pager (Pager # 519-654-5616) to talk with MV
