Input:Input time constant setting	None, 0.1 micro s, 0.2 micro s, 0.5 micro s, 1.0 micro s, 2.0 micro s and 10.0 micro s
Count function:No. of counters	4ch
Count function:Counter type	Linear counter / Ring counter
Count function:Counting range	Signed 32-bit (-2,147,483,648 to +2,147,483,647)
Count function:Max. input frequency	4 MHz / 8 MHz for individual input (phases A and B) (Duty ratio 50 plus or minus 10 %), 4 MHz / 8 MHz for direction discrimination input (Duty ratio 50 plus or minus 10 %), 4 MHz / 8 MHz /16 MHz for 2-phase input (Duty ratio 50 plus or minus 10 %, Phase shifting below 5 %)
Count function:Input signal	Phases A, B and Z
Count function:External I/O	Control signal input: 8 points (2 points/ch), External output: 8 points (2 points/ch)
Count function:Counter input type	Individual input (Phases A and B): 1 multiple, 2-multiple Direction discrimination input: 1 multiple, 2-multiple 2-phase input: 1 multiple, 2-multiple, 4-multiple
Measurement function:Frequency measurement function	Measures the intervals between the variations of count values, and calculates the frequency.
Comparison function:Target value match function	Depending on the count direction, sets or resets the output when the counter value reaches the target value.
External output:Comparison result output function	Outputs the result of comparison function.
Other functions:Capture function	Acquires the current count value from the edges of input signals, and stores it in the capture 0 register or capture 1 register. The value of the specified capture register will be overwritten by a new value and the old value will be discarded every time a counter value is captured.
Other functions:Interrupt input function	Available (2 points/ch, Max. 8 points/unit) (Note) The interrupt input function can be used for 8 points per unit and for a maximum of 8 units (max. 64 points) in the whole system. However, the entire scan time slows down as more interrupt programs are used. Minimize the use of interrupt programs. (Note) The priority order for interrupt inputs is as follows; In a unit, from the smallest interrupt bit. In the whole system, from the smallest unit number.
