honstly i have learned much from these playlist so Thanks for your Efforts, but i have a question on practical life scenario, i have four v90 drives controlled by S7 1500 cpu and lately i have randomly errors on two of them (HW Limit exceeds) while this is not occured , aslo from where i can know the real cause (is from Drive monitor Error Code or from the Commissioning Tab inside TO or from the PLC CPU diagnostic buffer )
If you are not using the HW Limit but it is causing trouble, please check P29300, it could be set = 6. If you are using HW Limit, properly check the sensor flicking.
Hello, I hope you can help me. I have an engine BG65S from dunkermotoren that i command with a driver PDC1000 and a PLC S7-1500, thanks to your video i learned how to create the telegram 750 and read the torque value but i got a Word value (that is supposed to be a torque value in Nm but not) and i see that you are using a LReal. How did you get this value ? Did you convert it ? Thank you
Once you activate Telegram 750, and download the configuration, your TO can read out the torq value, as shown in video 10:21. But different brand would do slightly different for preparing the data for telegram 750, many be doing % of the fully torque (full torque is your motor full torq, e.g 10.5 Nm), or the actual torque Nm value.
@@electricalautomation Hello thank you for your first answer. I verified the unit in the settings of my TO and it should be in Nm. After discussing in the siemens forum, it seems that my word value represent a torque purcentage as you said (so 16383 should be 100% of my available torque). I would like to retrieve a Nm value from it. My engine got a rated torque of 0,53 Nm (maximum 1,7) but there is a reductor of I = 100 so finally i got 38,69 Nm (based of the user manual of the engine), the point is that i'm not sure of the accuracy of this purcentage and i would not like to calculate the value in Nm from it, i am afraid that after too much calculation i will not have a torque value i can trust. If possible the best should be to directly have the value in Nm (LReal) from the telegram to have the best accuracy.
You are the Best teacher I have ever seen .
Thanks! Welcome!
Best TH-camrs on PLCs. Thank you!
Thanks Bro
Thank you very much for your explicaton.
Glad it was helpful!

Can use Torque Limiting for unwind and rewind machine ?
Yes, torque reduction is a common function while you are using speed to control tension for winders
@@electricalautomation Can you show next video how to use it ?
