INTERBUS Interface
The WRITE service on the "download parameter block" object starts a parameterization
mechanism on the UFI11A. This writes all the parameters specified in the user data area
of the object one after the other in the UFI11A itself or a connected inverter and therefore
sets the parameters of the UFI11A or the inverter. The UFI11A is addressed using
address 0. An inverter connected to the UFI11A is addressed using its SBus address.
The write service is terminated with a positive write response once the download para-
meter block has been processed successfully (i.e. all parameters transferred by the IN-
TERBUS fieldbus interface have been written). A negative write response is returned in
case of an error. The return code contains more detailed information about the type of
error, as well as the number of the parameter (no. 1 – 38) where the error occurred (see
example).
Example
Write error response for an error when writing the 11th parameter:
Error class: 8 Other
Error code: 0 Other
Additional code high: 11dec Error when writing parameter 11
Additional code low: 15hex Value too large
Note the following points when using the download parameter block:
•
Do not perform a factory setting within the download parameter block!
•
All parameters written after the parameter lock has been activated will be rejected.
"Last PCP index"
object
This object is 4 bytes long and, when read access is executed, it returns the numerical
value of the last index which can be addressed directly using the PCP services. PCP
accesses to indices greater than this numerical value must be made using the "MOVI-
LINK parameter channel with acyclical routing" object. Access is also possible using ob-
ject 8299 "MOVILINK parameter channel acyclical" if the parameters of the UFI11A are
to be addressed.
