When using the sina para function, it doesn't write

RB91

Hi,

traversing block commands are also just parameters, so you can او write it with SINA_PARA FB when using the PLC for communication. SINA_PARA acyclically writes / reads parameters from the drive. Please note that you need to set the input for the axis number to "2" for V90.

Hello, sir

Subject: I'm using epos mode for my this application

I'm using traversing block and I need to write parameter the same time, but when I use sina para function it doesn't write I don't know why and I use 111 Telegram and sina pos is OK just when I wanted use sina para I think it is not OK with together

Could you help me please ?

Split from How to write parameter of v90 without using telegram?.

Hello to every body

, hope you have good time 

Subject: I'm using epos mode for my this application (write parameter, example the  position for traversing block in V90 servo) I want to use sina pos and sina para together  but not work sina para , why?

Hello,

you can definetely use SINA_POS (handling the cyclic data of telegram 111) and SINA_PARA (to write drive parameters) together in your PLC program.

As I understood your SINA_POS works fine and you just have problems with SINA_PARA.

I think this will be an issue of correct parameterization of the SINA_PARA block. Can you maybe show some screenshots of your project? I would like to see the interface of your SINA_PARA and also the part where you define which parameters you want to change in the drive (in the instance DB I think)

Do you use the correct HW ID? -> I recommend to use the same as you used for SINA_POS.

Have you set axis number to "2"? In case of V90 you need 2. In case of SINAMICS G it must be "1". In case of S120 you need to check the correct drive object number of the axis.
