•
Capture and trigger on falling edge of the DC Link current waveform at
ACB test point “
Idc1
”.
•
Label the waveforms as “Vuv”, “Vuvs” and “Idc1”.
•
Save the worksheet as “Drift @ 15 Degree Lead Angle”, for example.

While performing a live synchronous transfer:
•
Capture motor voltage at ACB test point “
Vuv
” & bypass voltage at ACB
test point “
Vuvs
”.
•
Capture and trigger on falling edge of the DC Link current waveform at
ACB test point “
Idc1
”.
•
Label the waveforms as “Vuv”, “Vuvs” and “Idc1”.
•
Save the worksheet as “Synch on Motor 01”, for example.
