Delay times

Delay from input to output (main or second encoder)
when operating in quadrature AB
Delay from Z input to Z output (main or second encoder)
Delay from Freeze input signal to storing of the position
information
Difference in delay between storing the position information from
the main encoder and the position information from the second
encoder
