PTO-Read status location-Can I used it in project

[luciferc4]

Hello,

In V430-J-TR34, For motion control of servo system I used PTO functions. For moving function I used Relative with appropriate velocity and target position. In PTO read status function block I can see current position, velocity, etc... But, for real situation I can't solution. I'll describe with concrete data: I want to move object for 1500. Current position (in read status block, ML1), for example, is 10000. After moving, current position will be 11500. But, during moving happen stop and current position, for example, is 10600. With new start I want to move object to positon 11500!! move only 900mm after stop. I tried to used location ML1 in estimate, but that not work. On other side, I can't reset ML1 location too. All location from READ STATUS block are unavailable for any calculation or another function in ladder. Please, can someone hlp me how to solve it. In attach is red status blok with their parameters.

Thanks.

Could you just do an absolute move to your position?  This will move to your exact destination and not by how many pulses you tell it.  But you must set a "Home" location first to do this type of move.

Hi,

Thank you for interesting in Unitronics PLCs.

V430-TR34 PLC does supports simple PTO.

You can configure it in Hardware Configuration - High Speed Otputs (Step Control).

 

But this PLC model also have support for PTO - Pulse Training Output.

This supports acceleration, deceleration, and other Simple Motion Control function.

But before use this mode, you have to configure PTO.

 

There is PTO example in directory:

C:\Program Files (x86)\Unitronics\Unitronics VisiLogic_C\Examples\Version 900\Project examples\PTO\

V350_PTO example plus Jogging.VLP

Look how it realized, and I hope you will like it.

*Use only "PTO Read Status" without configuration is useless.

I hope you can realize your PTO better.

 

B.R.

Ola amigos tenho um V350-J-T2 como faço para controlar motor de passo para posicioname.

abraços.

Hello friends I have a V350-J-T2 how do I control step motor to position me.

hugs.

 

You will configure the High Speed Outputs (Step Control) tab in the hardware configuration.

To get you started, look in the Help under "HSO".  Then post your code with specific questions.
