T1-16S User's Manual
Input filter constant (ON/OFF delay time) can be set
by user program. The setting range is 0 to 15ms
(1ms units). Default value is 10ms. 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 5KHz for each channel.
Channel 1
Channel 2
Single phase Counts the number of pulses in a specified sampling
speed- time. The sampling time setting is 10 to 1000ms
counter (10ms units). 2 channels of pulse input are available.
The countable pulse rate is up to 5KHz for each
channel.
Channel 1
Channel 2
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 5KHz.
Phase A
Phase B
Reset
program when the interrupt input is changed from
OFF to ON (or ON to OFF). 2 points of interrupt input
are available.
X002 Interrupt 1 (I/O interrupt program #3)
X003 Interrupt 2 (I/O interrupt program #4)
The value of the analog setting adjuster is converted
into digital value (0 to 1000) and stored in the SW
register. 2 adjusters are provided on the T1-16S.
V0 SW30
V1 SW31
Variable frequency pulse train can be output. The
available pulse rate is 50 to 5000Hz (1Hz units).
Y020 CW or Pulse (PLS)
Y021 CCW or Direction (DIR)
Variable duty cycle pulse train can be output. The
available ON duty setting is 0 to 100% (1% units).
Y020 PWM output
