Resolution: The sine wave frequency can be up to 500 kHz but the resolution is reduced at high
frequency. Table 3-2 Interpolated information based on frequency and voltage level on page 11
shows the number of bits of interpolated information at different frequencies and with different
voltage levels at the drive encoder port.
