Input frequency

1 MHz maximum (500 kHz when the CPU unit is the KV-1000/700)

Count range

32 bits (unsigned: 0 to 4,294,967,295, signed: -2,147,483,648 to 2,147,483,647)


Count mode

Linear, ring

Input mode

· 2-phase 1×, 2-phase 2×, 2-phase 4×, 2-pulse (addition and subtraction) · Internal clock source (1 µs, 10 µs, 100 µs) · 1-pulse direction present or not present · Other channel matching output

Operation mode

· Up/down count mode · Count within set time mode · Preset count mode · Frequency count mode*1 · Enable integration count mode · Rotation counter A mode (pulse interval measurement)*1· Enable count mode · Rotation counter B mode (single rotation time measurement)*1


Count input

3 A-phase, B-phase, and Z-phase (preset) inputs for each channel for a total of 6 inputs; 5, 12, or 24 VDC input possible; line-driver input possible, photocoupler isolation (between each channel and between each phase)

Control input

1 enable input per channel for a total of 2 inputs, 12 to 24 VDC input possible, photocoupler isolation; 2 input capture inputs per channel for a total of 4 inputs, 12 to 24 VDC input possible, photocoupler isolation*2


Comparator matching output

2 for each channel for a total of 4; photocoupler isolation; rated load: 30 VDC, 0.1 A or less

Input capture function

By way of external input (4 inputs maximum)

Input filter function

Input time (adjustment) switching (5 types of numbers and 8 types of control)

Preset function

By way of preset (Z-phase) input or internal relay; selectable from rising edge, falling edge, and level (only when external input is used)

*1 When the KV-1000/700 is connected, only channel 0 can be used.
*2 Used for both enable input and input capture input 0.
