DESCRIPTION
Sine/Cosine Encoder
This menu is Context Enabled: It is visible when
Type = Sine/Cosine Encoder
Note, the sin/cos sensor physical waveforms are not bipolar, but center around an offset voltage, typically around 2.5v. The Peak-Peak voltage
swing may be as small a 1volt or up to 2.5 volts. If the sensor voltages go outside this range, position sensing will be faulty and not useable by the
VCL functions. In this case, a fault will be detected.
