8.2.1 Linear counter function
(1) Operation of the linear counter
This function counts pulses between -2147483648 (lower limit value) and 2147483647 (upper limit value).
The preset function and the coincidence output function can be used together.
(2) Overflow error
In linear counter, an overflow error occurs if the present counter value falls below -2147483648 (lower limit
value) in counting down or exceeds 2147483647 (upper limit value) in counting up.
If an overflow error occurs, "1" is stored in CH Overflow detection (Un\G8, Un\G40), the counting operation
stops, and the present value does not change from -2147483648 or 2147483647 even if pulses are input.
An overflow error can be cleared by performing the preset function.
When the preset function is performed, "0" is stored in CH Overflow detection (Un\G8, Un\G40) and the
counting operation can be restarted.
Overflow error status can be checked in the system monitor window. ( Page 108, Section 11.1 (1))
