3.3 Input Channel Settings
84
Configure these settings for each pulse channel on which you will be counting pulses
corresponding to revolutions, such as output from a rotary encoder or tachometer. The
revolution measurement is obtained by counting the number of pulses input per second.
Make these settings on the
[CH] screen.
