7000 “A” Frame 7000A-RM001A-EN-P – January 2011
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.
