Telegram 105 unable to unselect parameter 1522

 Hoping to get an answer here. When I add telegram 750 I get a link to parameters 1522 and 1523 positive and negative torque limits. This then generates an error as soon as I enable the drive stating that the limit is zero. I tried to write directly to those memory areas, but they get overwritten somewhere else. Also unable to deselect them from the telegram. Using Tia 14, starter 5.1.

anyone have good suggestions?

Thanks, Lars

Hello,

on TIA Portal side you are right, just enabling the additional torque data as you did already. On the drive side in STARTER/SCOUT you also need to enable the additional telgram 750. This is a little tricky, you need to do it by the following steps:

1. Offline add a supplementary telegram of length 1/3 to your drive (additionally to the standard telegram)

2. Download

3. go online and set p8864 = 750 -> now the BiCo connections are created automatically to the torque parameters

4. copy Ram to Rom and do an Upload

5. Offline generate the GSD file of the drive unit and install the generated GSD file to TIA Portal and connect it to the PLC.
