Remote transfer data
In some cases, altering parameter values via serial communication requires the use
of the SPA password. The password is a number within the range 1...999. The
default value for the SPA password is 1.
Password protection is removed by entering the password number in parameter
V160 and reinstated by writing the same password to parameter V161. Loss of the
auxiliary supply voltage also reinstates protection.
For example, to change a value of setting group 1, stage U> to 0.7 x U
n
, proceed as
follows:
•
Enter the password, WV160:1
•
Write a new value, WS41:0.7
•
Reinstate password protection, WV161:1
The SPA password can be changed via the serial bus by entering first the current
password in parameter V160, and writing then a new password to parameter V161.
