Encoder Input Pulse Options

  • If Phase B is a low signal and Phase A is a high signal, then count is increased.

  • If Phase B is a high signal and Phase A is a low signal, then count is decreased.

Addition/Cutback Phase A input pulse High Phase A input pulse Low
Phase B input pulse High - Cutback count
Phase B input pulse Low Addition count -

If Phase A input pulse is increasing, count is changed as follows:

  • If Phase B input pulse is Off, count is increased.

  • If Phase B input pulse is On, count is decreased.

Addition/Cutback Increasing Phase A input pulse Decreasing Phase A input pulse
Phase B input pulse Off Addition count -
Phase B input pulse On Cutback count -

If Phase A input pulse is increasing or decreasing, count is modified as follows:

  • If Phase B input pulse is Off, count is increased.

  • If Phase B input pulse is On, count is decreased.

Addition/Cutback Increasing Phase A input pulse Decreasing Phase A input pulse
Phase B input pulse Off Addition count Addition count
Phase B input pulse On Cutback count Cutback count

  • If Phase A input pulse occurs before Phase B input pulse, count is increased when Phase A pulse increases.

  • If Phase B input pulse occurs before Phase A input pulse, count is decreased when Phase A pulse decreases.

  • If Phase A increases/decreases, count is increased.

  • If Phase A input is faster than Phase B input at the Phase, count is decreased.

  • If Phase A input pulse and Phase B input pulse are increased/decreased, count is increased.

  • If Phase A input is faster than Phase B at the phase, count is increased.

  • If Phase B input is faster than Phase A at the phase, count is decreased.
