Input filter constant (ON/OFF delay time) can be set by
user program. The setting range is 0 to 15 ms
(1 ms units). Default value is 10 ms. This function is
applied for X000 to X007 (8 points as a block).
Single phase Counts the number of pulses of single phase pulse
up-counter train. 2 channels of pulse input are available. The
countable pulse rate is up to 5 kHz for each channel.
Channel 1 ¼ X000 count input, X002 reset input
Channel 2 ¼ X001 count input, X003 reset input
Single phase Counts the number of pulses in a specified sampling
speed- time. The sampling time setting is 10 to 1000 ms (10
counter ms units). 2 channels of pulse input are available. The
countable pulse rate is up to 5 kHz for each channel.
Channel 1 ¼ X000 count input
Channel 2 ¼ X001 count input
Quadrature Counts the 2-phase pulses whose phases are shifted
bi-pulse
90° each other. Counts up when phase A precedes,
counter
and counts down when phase B precedes. The
countable pulse rate is up to 5 kHz.
Phase A ¼ X000
Phase B ¼ X001
Reset ¼¼ X002
program when the interrupt input is changed from OFF
to ON (or ON to OFF). 2 points of interrupt input are
available.
X002 ¼ Interrupt 1 (I/O interrupt program #3)
X003 ¼ Interrupt 2 (I/O interrupt program #4)
into digital value (0 to 1000) and stored in the SW
register. 2 adjusters are provided on the T1/T1S.
V0 ¼ SW30
V1 ¼ SW31
Variable frequency pulse train can be output. The
available pulse rate is 50 to 5000 Hz (1 Hz units).
Y020 ¼ CW or Pulse (PLS)
Y021 ¼ CCW or Direction (DIR)
Variable duty cycle pulse train can be output. The
available ON duty setting is 0 to 100 % (1 % units).
Y020 ¼ PWM output
The above special I/O functions, except the v
analog setting functions, are available only in the DC input types.
