V90 - PTI - losing RDY status during work.

Hello everyone,

my setup:

V90 PTI - 6SL3210-5FB10-4UA1

Motor - 1FL6034-2AF2x-xLA

V90 controller by TM PTO4 - 6ES7 553-1AA00-0AB0

using Technology object. 

During process after 5-10 minutes without any obvious cause losing RDY status and stops reacting for TO commands (TO changing position but motor is physicaly not moving).

Any idea what I am doing wrong?

What is in the alarm history in the v90 and what is the active alarm (or alarms)?

Have you seen this sample application: https://support.industry.siemens.com/cs/document/109739053

It might solve at least once problem by using a different communication and control technology which automatically can retrieve the current alarm & warning codes from the V90, some of which you can detect and automatically handle, or perhaps suggest to the operator how to handle when automatic is not appropriate.

The problem is that there isn't any alarm shown on V- Assistant after it happen. Just every digital output is off and to start again I need to turn off SON signal, and turn on again.

There is no possibiltiy to change way of controlling because V90 does not have Profinet.

Where can I find alarm history in V assistant?

What about this project:

Or did someone order a V90 for position control and expect to pull it off with PTO / PWM:

Or maybe you want to just "wing it" on your own. In that case, you might need this reference which provides links to a great many reference documents which may provide valuable to your efforts:
