7 High-speed Counters
Determining High-speed Counters
Applicable Input Terminals
Terminals that can be used as high-speed counter inputs are shown in the following table.
The terminals that are used for high-speed counter inputs are also used for normal inputs, quick-
response inputs, interrupt inputs, and origin searches. The same input terminal can be used for only
one of these functions.
For example, if high-speed counter 1 is used, interrupt input 2, normal input 2, normal input 6, nor-
mal input 7, quick-response input 2, and origin input signal for pulse output 1 (when performing ori-
gin searches) cannot be used.
