1-4 About the Modules

EXAMPLE

Example of Multiplying Encoder Mode X1

X1 Multiplying Encoder Mode

Quadrature input signals are used to count on the leading (up

direction) OR trailing (down direction) edge of A for a bidirectional

count, and channel B is used to determine the direction.

[ B = leads A, Count = Down; B = follows A, Count = Up ]

X2 Multiplying Encoder Mode

Quadrature input signals are used to count on leading AND trailing

edges of A for a bidirectional count, and channel B is used to

determine the direction.

[ B = leads A, Count = Down; B = follows A, Count = Up ]

X4 Multiplying Encoder Mode

Quadrature input signals are used to count on leading AND trailing

edges of A AND B for a bidirectional count, and channel B is used to

determine the direction.

[ B = leads A, Count = Down; B = follows A, Count = Up ]
