High-speed counters

High-speed counter

No interrupt

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)

Count-check interrupt

(An interrupt can be generated when the
count equals the set value or the count
lies within a preset range.)

Interrupt inputs in counter mode
4 inputs, see note 1.

No interrupt

Incrementing counter (2 kHz)
Decrementing counter (2 kHz)

Count-up interrupt

Pulse outputs

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

Synchronized pulse control

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

Quick-response input

4 inputs, see note 1.

Maximum input signal width: 50 

µ

s

Analog settings

2 controls (setting ranges: 0 to 200 BCD)

Input time constant

Determines the input time constant for all inputs. (Settings: 1, 2, 3, 5, 10, 20, 40, or 80 ms)

Calendar/Clock

Shows the current year, month, day of the week, day of the month, hour, minute, and
second.

Error log

Records the time of occurrence and error code.

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 con-

trol functions.

3. This output is shared by the pulse output and synchronized pulse control

functions. These functions can be used with transistor outputs only.
