Siemens SINAMICS S200 - PTO Function

9.4.5 PTO function
Overview
Pulse T
rain Output is a simple and universal interface between a SIMATIC control and a SINAMICS
drive. PTO is supported worldwide by many stepper drives and servo drives and is used in many
positioning applications, for example, for adjusting or feed axes.
A pulse train encoder output which provides pulse signals can transmit the signals to the
controller to realize a closed-loop control system inside the controller, or transmit them to
another drive as pulse train setpoint for a synchronous axis or as control interface of another
device (for example, a line scan camera).
Description of function
PTO is also referred to as pulse/direction interface. The pulse/direction interface comprises two
signals.
• PTO direction output
The direction output de󹪝nes the traversing direction. You can de󹪝ne whether the PTO
position actual value should be inverted via p4422:
– Positive logic (= not inverted, default setting)
– Negative logic (= inverted)
• Maximum output frequency
The maximum output frequency represents the velocity and the number of output pulses for
the section to be traversed. You can set the maximal output frequency of the pulse train
output via p4405.

The electronic gear ratio is a multiplier factor to the pulse train output to a controller.
