Figure 124: CCW Electrical Angle Plot
Where:
EUA = Motor Encoder “U” Angle
If EUA is >360° subtract 360°.
Next, use the oscilloscope to examine the phase relationship between Z and V
TS
. Use Figure
124 to determine the electrical angle at the rising edge Z. This is the Encoder Marker
Electrical Angle.
