● PTO (A/B phase-shifted): If you select a PTO (A/B phase-shifted) option, then both

outputs pulse at the speed specified, but 90 degrees out-of-phase. It is a 1X

configuration, meaning one pulse is the amount of time between positive transitions of

P0. In this case, the direction is determined by which output transitions high first. P0

leads P1 for the positive direction. P1 leads P0 for the negative direction.

The number of pulses generated is based upon the number of 0 to 1 transitions of Phase

A. The phase relationship determines the direction of movement:

PTO (A/B phase-shifted)

Phase A leads phase B (positive movement)

Phase A lags phase B (negative movement)

● PTO (A/B phase-shifted - fourfold): If you select a PTO (A/B phase-shifted - fourfold)

option, then both outputs pulse at the speed specified, but 90 degrees out-of-phase. The

fourfold is a 4X configuration, meaning one pulse is the transition of each output (both

positive and negative). In this case, the direction is determined by which output

transitions high first. P0 leads P1 for the positive direction. P1 leads P0 for the negative

direction.

Fourfold is based upon positive and negative transitions of both Phase A and Phase B.

You configure the number of transitions. The phase relationship (A leading B or B leading

A) determines the direction of movement.

PTO (A/B phase-shifted - fourfold)

Phase A leads phase B (positive movement)

Phase A lags phase B (negative movement)
