Omron CPM1A 3 I/O Specifications, CPU Unit Input Specifications, Increment Mode 5 kHz Max

Specifications Section 2-1

Either switch the CPM1A to RUN or MONITOR mode, or turn off and on power to the CPM1A after changing from a Programming Device any data that is backed up in flash memory. This data includes the user program, read-only DM area (DM 6144 to DM 6599), and the PC Setup (DM 6600 to DM 6655).

Note Figures in parentheses are for IN00000 to IN00002.

Note Using the PC Setup, 1, 2, 4, 8, 16, 32, 64, or 128 ms can be selected. When IN00000 through IN00002 are used as high-speed counter inputs, the delays are as shown in the following table.

Input	Increment mode	Differential phase mode
IN00000 (A-phase)	5 kHz	2.5 kHz
IN00001 (B-phase)	Normal input
IN00002 (Z-phase)	ON: 100 ∝ s min.; OFF delay: 500 ∝ s min.

The minimum delay is as follows.

Increment Mode (5 kHz Max.)

200 ∝ s min.

90 ∝ s min.

ON

A phase

OFF 90 ∝ s
