Manual, 12/2017, A5E40898741-AA

3.2.1.3

Operating mode: PTO

The PTO (Pulse Train Output) mode can be used to output position information. This allows

you to, for example, control stepper motor drives or simulate an incremental encoder. The

frequency of the pulses represents the speed, while the number of pulses represents the

distance. The direction can also be specified by using two signals per channel. You can use

a PTO channel for setpoint output (drive) for an axis technology object.
PTO mode is divided into the following four signal types:

●

PTO (pulse (A) and direction (B)): If you select the PTO signal type (pulse (A) and

direction (B)), an output (A) controls the pulses and an output (B) controls the direction. B

is 'High' (active) when pulses are generated in a negative direction. B is 'Low' (inactive)

when pulses are generated in a positive direction.

①

Positive direction of rotation

②

Negative direction of rotation

●

PTO (Count Up (A) and Count Down (B)): When you select PTO when you select the

PTO signal type (count up (A) and count down (B)), an output (A) outputs pulses for

positive directions and another output (B) outputs pulses for negative directions.

①

Positive direction of rotation

②

Negative direction of rotation
