Live Synchronous Transfer
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.
