4-2 Counter Input 6222 User’s Manual

Encoder Settings

Resolution

The encoder resolution, which is the number of full quadrature cycles per full shaft

revolution (360 mechanical degrees). Choices are:

 X1 – One count per cycle (default)

 X2 – Two counts per cycle

 X4 – Four counts per cycle

Encoder Sources

There are three encoder sources – A, B, or Z. For each source select one of the

digital pins (Digital Line 0 – Digital Line 7)

When set for Encoder measurements, the device can count "negative" values;

that is, when counting down, the encoder will continue counting down below 0.

This capability is useful when calculating the position of an encoder.
