Features

This section describes the features of the QD63P6.
(1) Wide range of expression on counting (from -2147483648 to 2147483647)
Count values can be stored in 6 channels and 32-bit signed binary.
(2) Switching of the maximum counting speed
Since the QD63P6 can switch between 200 k, 100 k, and 10 k, gradual rise/fall
pulses can be correctly counted.
(3) Pulse input selection
Pulse input can be selected from 1 multiple of 1 phase, 2 multiples of 1 phase, 1
multiple of 2 phases, 2 multiples of 2 phases, 4 multiples of 2 phases, and CW/CCW.
(4) Counter format selection
Either of the following counter formats can be selected.
(a) Linear counter format
From -2147483648 to 2147483647 can be counted and an overflow can be
detected when the count range is overrun.
(b) Ring counter format
Counts are repeatedly executed between the ring counter upper limit value and
ring counter lower limit value.
(5) Coincidence detection
By presetting the coincidence detection point of an arbitrary channel, the detection
point is compared to the present counter value, ON/OFF signal can be output
according to the result, and an interrupt program can be started.
(6) The periodic pulse counter function is supported.
The periodic pulse counter function stores the present and previous counter values at
every preset time while signals are input.
(7) Simple settings using the utility package
The utility package (GX Configurator-CT) is sold separately.
Although the usage of the utility package is arbitrary, it enables to make initial settings
and auto refresh setting on the screen, which lead to load reduction of the sequence
programs and simplicity in checking the setting status and operation status.
