Quick-response Inputs
The CPM1-10CDR-
j
PCs have 2 quick-response input terminals and the
CPM1-20CDR-
j
/30CDR-
j
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.

CPM1 PCs are equipped with an interval timer which can be set from 0.5 ms to
319,968 ms in units of 0.1 ms. The timer can be set to trigger a single interrupt
(one-shot mode) or repeat scheduled interrupts (scheduled interrupt mode).
