Figure 3–27 RPM vs PPR Chart
Figure 3–27 provides a reference for allowable maximum RPMs when using an encoder with a given
PPR. Theses combinations keep the input frequency within the allowable limits for the DSP7000.
Quad Deg is designed to be used with very slow RPM applications with a quadrature encoder in the
system. The speed of the system is limited to 100 RPM. The pulse per revolution (ppr) can be set
from 1000 to 99999 ppr. The angle to perform the measurement can be set from 10 to 90 degrees.
The maximum frequency from the encoder can be as high as 200 kHz.
AI 1 is designed to take the analog voltage from the IO card associated with the channel being setup
and use that analog voltage as the speed input. A scale factor can be applied to the input.
