Input filter constant (ON/OFF delay time) can be set<br />
by user program. The setting range is 0 to 15ms<br />
(1ms units). Default value is 10ms. This function is<br />
applied for X000 to X007 (8 points as a block).<br />
Counts the number of pulses of single phase pulse<br />
train. 2 channels of pulse input are available. The<br />
countable pulse rate is up to 5KHz for each channel.<br />
Channel 1 … X000 count input, X002 reset input<br />
Channel 2 … X001 count input, X003 reset input<br />
Counts the number of pulses in a specified sampling<br />
time. The sampling time setting is 10 to 1000ms<br />
(10ms units). 2 channels of pulse input are available.<br />
The countable pulse rate is up to 5KHz for each<br />
channel.<br />
Channel 1 … X000 count input<br />
Channel 2 … X001 count input<br />
Counts the 2-phase pulses whose phases are shifted<br />
90° each other. Counts up when phase A precedes,<br />
and counts down when phase B precedes.<br />
The countable pulse rate is up to 5KHz.<br />
Phase A … X000<br />
Phase B … X001<br />
Reset …… X002<br />
Interrupt input function Immediately activates the corresponding I/O interrupt<br />
program when the interrupt input is changed from<br />
OFF to ON (or ON to OFF). 2 points of interrupt input<br />
are available.<br />
X002 … Interrupt 1 (I/O interrupt program #3)<br />
Analog setting<br />
function<br />
X003 … Interrupt 2 (I/O interrupt program #4)<br />
The value of the analog setting adjuster is converted<br />
into digital value (0 to 1000) and stored in the SW<br />
register. 2 adjusters are provided on the <strong>T1</strong>-<strong>16S</strong>.<br />
V0 … SW30<br />
V1 … SW31<br />
Pulse output function Variable frequency pulse train can be output. The<br />
available pulse rate is 50 to 5000Hz (1Hz units).<br />
Y020 … CW or Pulse (PLS)<br />
Y021 … CCW or Direction (DIR)<br />
PWM output function Variable duty cycle pulse train can be output. The<br />
available ON duty setting is 0 to 100% (1% units).<br />
Y020 … PWM output<br />
SW16 setting<br />
is necessary to<br />
use this<br />
function. (Note)<br />
Only one<br />
among these 4<br />
functions can<br />
be selected.<br />
SW16 is used<br />
to select the<br />
function.<br />
(Note)<br />
No function<br />
selection is<br />
required.<br />
Either one<br />
between these<br />
2 functions<br />
can be used.<br />
SW26 is used<br />
to select the<br />
function.(Note)<br />
