Controlling sinamics v90 with s7-300cpu?

Hello

I am wonering if its possible to do position control using a CPU 315-2 PN/DP with a V90 6SL3210-5FB10-4UF1 Drive.  Or do I need to use a newer PLC like the 1200 or 1500 series?

I only need to do simple moves with these drives, nothing super complicated.

any help is appreciated.

Hello skdahfgsal;

This Application Example shows how to program a simple speed control for a V90 with a S7-300, using Profinet.

Hope this helps,

thank you for the reply

I have seen that example but that is not exactly what I want, I would like to use the drive to move back and forth on a rack and pinion using positioning with the encoder.

So I am wondering if it is possible to do "positioning" using this setup?

thanks again.

Hello skdahfgsal ;

In that case, look at the DriveLib function library, it will work with S7-300 under TIA Portal v14 to v16.

The SINA_POS block should be able to control and position a V90 servo.

Hope this helps,

I will look into this.

I have gotten the communication working and I am able to move the drive from the plc, with your help, and the help of this video: https://www.youtube.com/watch?v=dT8zHc-phNI  . 

The problem now is when I change the operating mode of the drive to operating mode 2(absolute positioning) it automatically turns off "enable Axis", when I manually turn on enable axis, the operating mode switches to mode 3.  Any idea what could be causing this?

thanks again.

never mind my issue was I had certain variable overlapping in memory. everything works now!

thanks
