Input Signal Types
Select the input type using the following device variables for CJ-series Unit (for setting). For every
Counter, you can select the Signal Type.
Phase Differential Signals are connected to the inputs A, B and Z of every Counter. The count direction
is determined by the phase angle between input A and input B. If signal A leads to B, the Counter incre-
ments. If signal B leads to A, the Counter decrements.
z
Multiplication x1
By default the Counter is configured for Multiplication by 1. If the Counter counts up (signal A leads
to signal B), pulses are taken into account by the Counter on the rising edges of signal A. If the
Counter counts down, pulses are taken into account on the falling edges of input A.
