Input time constant
Calendar/Clock
Error log
Interrupt inputs
4 inputs, see note 1.
Response time: 50 µs
Interval timer interrupts
1 input
Set value: 0.5 to 319,968 ms
Precision: 0.1 ms
High-speed counter
1 input, see note 2.
Differential phase mode (5 kHz)
Pulse plus direction input mode (20 kHz)
Up/down input mode (20 kHz)
Increment mode (20 kHz)
Interrupt inputs in counter mode
4 inputs, see note 1.
Incrementing counter (2 kHz)
Decrementing counter (2 kHz)
2 outputs:
Single-phase pulse output without acceleration/deceleration (See note 3.)
10 Hz to 10 kHz
2 outputs:
Variable duty ratio pulse output (See note 3.)
0.1 to 999.9 Hz, duty ratio 0 to 100%
1 output:
Pulse output with trapezoidal acceleration/deceleration (See note 3.)
Pulse plus direction output, up/down pulse output, 10 Hz to 10 kHz
1 point, see notes 2 and 3.
Input frequency range: 10 to 500 Hz, 20 Hz to 1 kHz, or 300 Hz to 20 kHz
Output frequency range: 10 Hz to 10 kHz
4 inputs, see note 1.
Maximum input signal width: 50 µs
2 controls (setting ranges: 0 to 200 BCD)
Determines the input time constant for all inputs. (Settings: 1, 2, 3, 5, 10, 20, 40, or 80 ms)
Shows the current year, month, day of the week, day of the month, hour, minute, and sec-
ond.
Records the time of occurrence and error code.
Note
1. These four inputs are shared by interrupt inputs, interrupt inputs in counter
mode, and quick-response inputs, but each input can be used for only one
purpose.
2. This input is shared by the high-speed counter and synchronized pulse
control functions.
3. This output is shared by the pulse output and synchronized pulse control
functions. These functions can be used with transistor outputs only.
Variations/Details
Scheduled interrupts
One-shot interrupt
No interrupt
Count-check interrupt
(An interrupt can be generated when the
count equals the set value or the count
lies within a preset range.)
No interrupt
Count-up interrupt
