*: Waveform cannot be measured because it is impossible to turn the power switch on (READY) with the inverter cover open.
2. Oscilloscope waveforms
HINT: Oscilloscope waveform samples are provided here for informational purposes. Noise and fluttering waveforms have been omitted.





(a) Waveform 1 (rear motor switch U signal)










(b) Waveform 2 (rear motor switch W signal)










(c) Waveform 3 (rear motor switch V signal)










(d) Waveform 4 (generator switch U signal)










(e) Waveform 5 (generator switch W signal)










(f) Waveform 6 (generator switch V signal)










(g) Waveform 7 (motor switch U signal)










(h) Waveform 8 (motor switch W signal)










(i) Waveform 9 (motor switch V signal)










(j) Waveform 10 (DC/DC converter voltage switch signal)










(k) Waveform 11 (communication signal from MG ECU to hybrid vehicle control ECU)





HINT: The waveform will vary depending on the content of the digital communication (digital signal).





(l) Waveform 12 (communication signal from hybrid vehicle control ECU to MG ECU)





HINT: The waveform will vary depending on the content of the digital communication (digital signal).





(m) Waveform 13 (MG ECU communication request signal)










(n) Waveform 14 (MG ECU communication clock signal)










(o) Waveform 15 (rear motor resolver signal)





HINT: Pulse cycle A becomes shorter as the rotor speed increases.





(p) Waveform 16 (generator resolver signal)





HINT: Pulse cycle A becomes shorter as the rotor speed increases.





(q) Waveform 17 (motor resolver signal)





HINT: Pulse cycle A becomes shorter as the rotor speed increases.
