MOTOR CONTROL WAVEFORMS
The oscillograms that follow were made with a Tektronix 422 oscilloscope and a C-30
Camera. Probe connections, scope setting and operating conditions are given for
each.
For the waveforms, the letter W followed by a number identifies the point.in the
circuit at which the voltage appears on page 10 of the schematics in Chapter 6.
