CPM2A/CPM2C High-speed Counters
Function
2-2
Interval timer interrupts
Synchronized pulse control
Cannot be used simultaneously.
Interrupt inputs
Can be used simultaneously.
Interval timer interrupts
Can be used simultaneously.
High-speed counters
---
Interrupt inputs (counter mode)
Can be used simultaneously.
Pulse outputs
Can be used simultaneously.
Quick-response inputs
Can be used simultaneously.
Input time constant
See note.
Clock
Can be used simultaneously.
Note When inputs 00000 to 00002 are set for use as a high-speed counter, the input
time constants for the relevant inputs are disabled. The input time constants remain in effect, however, for the values for refreshing the relevant input relay
area.
Operation Example
Select the input mode and reset
method.
Input mode: Differential phase input, pulse + direction input, up/down input,
or increment
Reset method: Phase-Z + software reset, or software reset
No interrupts (Read high-speed counter PV, or read range comparison results)
Select the interrupts to be used.
Target value comparison interrupts
Range comparison interrupts
Wire the inputs.
Input numbers: 00000, 00001, 00002
High-speed counter setting
PC Setup (DM 6642)
Input mode: Differential phase input, pulse + direction input, up/down input,
or increment
Reset method: Phase-Z + software reset, or software reset
CTBL(63): Register comparison table, start comparison
Create a ladder diagram program.
INI(61): Change PV, start comparison
PRV(62): Read high-speed counter PV, read high-speed counter comparison
status, read range comparison results
SBN(92) and RET(93): Create interrupt subroutine program
(when count-check interrupts are used)
