Quick-response Inputs The CPM1-10CDR- PCs have 2 quick-response input terminals and the
CPM1-20CDR-/30CDR-(-V1) PCs have 4 quick-response input terminals.
(The same terminals are used for quick-response inputs and interrupt inputs.)
Quick-response inputs have an internal buffer, so input signals shorter than one
cycle can be detected.
