Figure 8: Waveform After MotorShield
™
This waveform illustrates typical filter output voltage waveforms when measured from line to line.
If the measured waveform does not resemble a sine wave like this illustration, and looks more like
the filter input waveform, troubleshoot filter wiring and components.
Warning
Only qualified electricians should carry out all electrical installation and maintenance
work on the MotorShield™.
Exercise caution when checking waveforms with an oscilloscope.
Use a dual probe, differential input set-up, or other means of isolating the scope
chassis from the motor voltage.
Disconnect power when attaching and removing the probes.
