Table 14 - Encoder Resolution 20,000 lines/mm
For example, an encoder resolution of 128 and Overspeed Response Time of
42 ms results in a speed resolution accuracy of ±19.865 RPM if your Safe
Maximum Speed is configured for 100.0 RPM. An SMS Speed fault can occur
when encoder 1 is at 80.135 RPM. However, the SMS Speed fault cannot occur
until encoder 1 reaches 119.865 RPM.
