Write Access to a Parameter

As a basic principle, write access to a parameter is carried out as follows:

IDN of the parameter, data block element number, w, operating data

(Carriage Return)

After the writing operation the drive responds with its prompt again.

In order to access the parameter value of the P-0-4073 parameter, for

example, the following input is required:

Step 1

Send request e.g.:

"P-0-4037,7,w,1000" (CR)

Step 2

Drive received character.

Drive repeats request (echo)

Character sequence ":>" found in

receiver buffer?

Compare ok? Transmission error

Step 4

Delete request in receiver buffer.

All characters to 1st "CR"

(inclusive).

Step 3

To check transmission compare request

with receiver buffer (string compare).

yes

Next character "#" in

receiver buffer?

Parameter succesfully written

yes

Contents of receiver buffer:

"P-0-4037,7,w,1000" (CR)

[#xxxx (CR)] "E01:>"

Error occurred during

parameter access.

Error code: #xxxx
