Up & Down - Omron CJ1W-CT021 Operation Manual

Input Signal Types
Multiplication x2
Multiplication x4
3-3-2 Up & Down
Increment pulse
Decrement pulse
To increase the resolution of the incremental encoder the Counter can be config-
ured for Multiplication by 2. If the Counter is up-counting (signal A leads to signal
B) pulses are taken into account by the Counter on the rising- and falling edges of
signal A. If the Counter is down-counting pulses are also taken into account on the
rising- and falling edges of signal A.
To further increase the resolution of the incremental encoder Multiplication *4
should be selected. If the Counter is up-counting (signal A leads to signal B)
pulses are taken into account by the Counter on the rising- and falling edges of
signal A and signal B. If the counter is down-counting pulses are also taken into
account on the rising- and falling edges of signal A and B.
Note For Counter Reset options (Z-input included) refer to 3-6 "Reset Signals".
With this Signal Type the Counter increments on the rising edge of pulses applied
to input A and decrements on the rising edge of pulses applied to input B.
