Good afternoon forum,

Im programing a V90 with a hmi and a s71200,

The servo motor only seems to go in one dirrection, when i do a simple jogging it goes in both dirrections but when its controlled from the s71200 1214C it only works in one dirrection even when i move it with commissioning.

Im using PTI on the V90 to move a ball screw table in x and y.

Does anyone now whats happening?

How V90 is interfaced to S7-1200? Via profinet, MODBUS etc?

Please check below FAQ may help you.

V90 Control

Hello,

X8 connector is for manual/JOG movement.

If S7-1200 PLC is controlling drive via PROFINET , please check the value p0922 i.e. type of telegram defined, check p29303 & p29304. 

I have been reading the manual and it hasent helped as of yet, 

The parameters 29303 and 29304 are on CWL and CCWL and p0922 dosent exist on my list

Hello,

Please check the value of p0922. 

Please check the status of control word 1 i.e. STW1 when you operate/control drive by PLC & report here.

Hello,

Please check the value of p0922. 

Please check the status of control word 1 i.e. STW1 & report here.

 I cant seem to find that parameter, do you know where i can see it?

I just re-read your answer, the drive is being controled by PTI and the only conection between the s7-1200 and the v90 is the X8 connector

Are you sure you have established profinet communication with PLC?

How much is the value in p0922 =?

Please refer following FAQ for detailed information. Please go thru the Documentation (1,4 MB) file.

Speed Control of SINAMICS V90 with SIMATIC S7-1200 via PROFINET

I just edited my last answer,

I read your message wrong there is only a profinet conection with the 1200 and the hmi , the only connection between the cpu and the drive is the conector x8
