6.1.2 Performance of Built-in High-speed Counter
Number of channel
There are four channels for the built-in high-speed counter.
The channel number allocated for the high-speed counter will change depending on
the function being used.
Counting range
K-2,147,483,648 to K2,147,483,647 (Coded 32-bit binary)
The built-in high-speed counter is a ring counter. Consequently, if the counted
value exceeds the maximum value, it returns to the minimum value. Similarly, if the
counted value drops below the minimum value, it goes back to the maximum value
and continues counting from there.

Note
When the linear interpolation instruction F175 or the circular
interpolation instruction F176 is used, the value for the target
value or the amount of travel should be set so that it is within the
range indicated below.
-8,388,608 to +8,388,607 (24-bit binary, with sign)
The F175 and F176 instructions can be used only with the C32T2
control unit.
