Multiplication x2
To increase the resolution of the incremental encoder, the Counter can be configured for Multiplica-
tion by 2. If the Counter counts up (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 counts down, pulses are also
taken into account on the rising- and falling edges of signal A.
z
Multiplication x4
To further increase the resolution of the incremental encoder, the Multiplication x4 should be
selected. If the Counter counts up (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 counts down, pulses
are also taken into account on the rising- and falling edges of signal A and B.
Additional Information
For Counter Reset options (Z-input included) refer to 3-6 Reset Counter.
With this Signal Type the Counter increments on the rising edge of pulses applied to input A, and dec-
rements on the rising edge of pulses applied to input B.
