yes sir you are correct , but i am getting confused  between pkw & status word.

PZD = data send from PLC to drive

PKW = data send from drive to plc

Then what is "Status word"  defination.

 Hello Vasule;

If you read the earlier answers in this thread, for example those form Chirayu Shah and Aryzing, you will have a good portion of your question answered. And the manual suggested by Technology Team contails all the detailed information on telegrams and cyclic communication with the drive.

Now, simply to clear up a few things, here are some basic definitions (check and validate from the manual, please):

-PZD, German abbreviation for Process Data, is a section of a telegram used to read/write commands, status and values to/from the drive. PZD includes (sends to the drive) the Control Word (CU_STW1), individual bits for start/stop, direction, jog.... written as a single word; The Speed reference... and receives from the drive the equivalent statuses or values configured for the telegram. The Status word you are asking about is the reply from the drive to the Control Word sent by the CU.

-PKW: German abbreviation for Parameter Values, are a distinct section of specific telegrams that are used in acyclic communications with the drive, to read/write one drive parameter at a time. Look in the manual Communications, acyclic communication. 

Do you see now that a Status Word (part of the PZD) has no connection to the PKW?

Hope this helps,
