Outputs
12.3.4 L_DCO_TransferDriveParameter
This FB reads and write the parameters of a Lenze inverter (logic axis) that is connected to the
Controller via a bus system. The parameters are defined via an array structure.
Inputs
Identifier/data type Information/possible settings
xDone
BOOL
TRUE: Read request completed
xBusy

Status output "Read request sent"
TRUE The read request has been transmitted to the system. The FB waits
for the response of the request.
FALSE No read request active
xError
BOOL
Error status output
TRUE During the processing an error has occurred
FALSE No error
eError
L_DCO_Error
Error number
sValue
STRING
Read parameter value
byNrOfByte
BYTE
Length of the read value
