What to write on "LaddrSP" and the "LaddrAV" inputs?

HI!
I have a et200s, IM 151-8 CPU, and a G120C PN driver connected. I can control the motor from "Control Panel" in Tia portal and i have connection. But i dont really know how to controll the driver from PLC? I have choosed the SINA_POS function but i dont know what to write on "LaddrSP" and the "LaddrAV" inputs. Does someone have a picture or can explain? 

I have choosed standard telegram 1 and inputs starts at 265 and outputs at 256. 

Thanks

Split from SINA_SPEED LAddrSP/LAddrAV-input.

Hi,

LaddrSP and LaddrAV means something like:

logical address setpoint

logical address actual value

So it means that there are 2 separate addresses in case the input direction has another address than the output direction. I think in most cases the addresses are the same so you just put the same value to both inputs (e.g. 256 at both inputs)

I have tried to just write "256" at both them inputs but nothing happens,

The only thing i can do is when i do an move instruction and move 16#4FE to PQW256, the driver acknowledges all faults.  Other than that i cant run in it.

Hi,

DiagID 80B1 means that the communication area of the partner (drive) is too short.

So please check whether the drive really has configured standard telegram 1 with length 2/2 words (not only in the offline project but also online downloaded to the drive).

Please check whether the hardware config was downloaded to the PLC.

And also check again the I/O address - but I guess this is correct.

If you look at the control bits within the control word (which is QW256 in your example), 16#4FE is the collection of bits that does everything except turn the motor on.

16#4FF turns the motor ON, but please do not use hex to manage your drive's control word when there are much better ways to handle it.

Telegram 1 is configured with 2 input words and 2 output words. In your case:

Configure tags something like this (tag names to suit)

IW256 Drive_1_Status_Word

IW258 Drive_1_Speed_Feedback

QW256 Drive_1_Control_Word

QW258 Drive_1_Speed_Setpoint

Look at the telegram configuration and slide things up and over a bit so you can see down in the bottom pane the IO tags available for the telegram.

I have checked the telegram, what I can see its Telegram 1 both online and offline. Downloaded several times and the input addresses is 256-259 and output is 256-259. 

So somehow its not the right value at the LaddrSP and LaddrAV inputs even though i have wrote 256 at both inputs. Or should i write qw256?
