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
yes
no
Next character "#" in
receiver buffer?
Parameter succesfully written
no
yes
Contents of receiver buffer:
"P-0-4037,7,w,1000" (CR)
[#xxxx (CR)] "E01:>"
Error occurred during
parameter access.
Error code: #xxxx
Communication with drive not
possible
-> check address
-> check setting
-> check connection
Timeout ?
no
no
yes
