Hello, I am trying to use the project in the link.  There is no problem in working in the forward direction, but I want it to rotate in the reverse direction only with the signal without entering the (-) value in front of the Speed ​​value in the reverse direction.  I don't know which signal I should use for this.  In other words, if the speed part is 900 while rotating in the forward direction, I write (-900) and it rotates in the reverse direction.  But how can I do this with just the signal without changing the value.

Hello, i hope this help to you. We have a sinamics that inverse the rotation so:

Control word 1 / profibus

P1113 Direction reversal setpoint (1=inversion)

Bye!

SINAMICS G: Speed control of a G110M/G120/G120C/G120D using S7-300/400F (STEP 7 V5) with PROFINET/PROFIBUS and Safety Integrated and HMI

This example project is using Telegram 352. In the control word, there should be one bit to activate reverse. So when you want to run forwards, you just activate ON/OFF1 bit. When you want to run reverse, you activa ON/OFF1 & Direction Reversal, then the drive will reverse.

 sorry but my english level is not good enough.  I think you are talking about here.  Which one do I need to enable here? Please see attachment.

 If you look at your picture, can you fin Direction reversal from it?
