Hi, I have the same problem. Drive runs just fine with telegram 1. But when I add telegram 750 it stops running. How do I correctly send the parameters to the drive using profinet? ------------------------------------------------------------------------------------------ |

I understand. S7-1200 PLC. 3x V90 drive. One of them configured as a technology object. The other 2 with SinaSpeed I want to read the torque (almost real time) of these two drives. With SinaParaS it takes 200 to 400ms to read a reliable torque value. That is to long for my aplication. When configured only with telegram 1, the motors run. But when I use telegram 750 in addition it thinks it's running but it isn't. See attached pictures. Configuration should be good. Cant seem to get it to work wit telegram 750, which should give me a faster readout of the torque values I think. Attachment123.zip (436 Downloads) |

If you can change V90 Telegram from 1 to 352, that is all you need to do - and change it in the PLC configuration too. However, I do not think telegram 352 is available on V90.
From another forum post (you could have searched and found several similar requests): The first reply offers suggestions.

Sadly telegram 352 is not available on V90. I saw that topic before. I already know, when selecting telegram 750. The torque values in the drive are automatically set to 0. That's why my motors stop running. You need to send the torque values to the drive with profinet directly and not using SinaParaS. But I cant figure out how to do that. I already tried, see picture from my first post, but that doesnt work. |

Are you able to add a free telegram and then assign the torque value to the first word in the free telegram? That's a great work-around. Are Telegram 102 and 105 both unavailable in the V90? If so, you can configure the S7-1200 to accept a "free telegram" and manually handle the words coming from the drive.
