PTO output.

Hi,

I have some questions:

1. Which case will we use PTO Output in S7-1512C-1 PN?
2. Can we use PTO Output in S7-1512C-1 PN to control step motor?
3. How to control step motor without Technology objects in S7-1512C-1 PN?

I would like to have some experts to answer my questions.

Thanks.

 hi quinn,

from the manual of S7-1512C:

S7-1512C manual, page 55

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.

Have a look in the manual of the 6ES7512-1CK00-0AB0:

SIMATIC S7-1500 CPU 1512C-1 PN

Chapter 3.2 describes how to handle the Pulse-Generators.

There´s a control- and feedback-interface in the IO-Data where it can be controlled.

hope this helps,

regards,
