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 K+2, 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 (Coded 24-bit binary)
The F175 and F176 instructions can be used only with the C32T2, C28P2, C32T2H and C28P2H control
units.
