Purpose: To show the measured V PWM value (see V PWM) divided by the fundamental frequency on vari- able ac motor speed drives

Accuracy: % Vrms + % Hz

Voltage unbalance drive input

Purpose: To show the highest percentage difference of one of the phase vs average of the 3 true-rms voltages

Accuracy: Indicative percentage based on Vac+dc values

Voltage unbalance drive output and motor input

Purpose: To show the highest percentage difference of one of the phase vs average of the 3 PWM voltages

Accuracy: Indicative percentage based on V PWM values

Current unbalance drive input

Purpose: To show the highest percentage difference of one of the phase vs average of the 3 AC current values

Accuracy: Indicative percentage based on Aac+dc values

Current unbalance drive output and motor input

Purpose: To show the highest percentage difference of one of the phase vs average of the 3 AC current values

Accuracy: Indicative percentage based on A ac values

Rise and fall time Readings: Voltage difference (dV), time difference (dt), voltage vs time difference (dV/dt), overshoot

Accuracy: As oscilloscope accuracy Harmonics and spectrum
