4-3
Linear Mode
A total of 16 ranges with upper and lower limits between –8,388,608 and
8,388,607 can be set in this mode and when the count value is within the
ranges, the High-speed Counter Unit will turn an output ON.
4-3-1
Operation Example
This example uses the following lower and upper limits with the outputs to be
turned ON.
If the present counter value is 3,000, outputs 7, 6, and 5 will be turned ON
because the present counter value will be within ranges 1 and 2, in which
case the OR of the outputs will be turned ON.
If the present counter value is –5,000, outputs 3, 2, and 1 will be turned ON
because the present counter value will be within ranges 0 and 3.
In the case where ranges of counters 1 and 2 are different from each other, if
the present counter value is within a range of counter 1 or 2, the OR of out-
puts corresponding to the range will be turned ON.

Configuration of Range
Note
The configuration of the range in linear mode is briefly described in the follow-
ing to explain the functions of the High-speed Counter Unit. Besides the set-
tings described in this section, a variety of settings, such as operating mode,
input type, and counter reset condition settings, are required. Refer to
