12.3.6 L_DCO_WriteDriveParameter
This FB writes a parameter of a Lenze inverter (logic axis) that is connected to the Controller via a
bus system.
• Parameter values of max. 32 bits can be read.
• The parameter to be read can be defined as index or code number.
• The FB is independent of the used bus system.

Axis
L_DCO_AXIS_REF_BASE
Connection of the axis data of the controller (Logic nodes)
xExecute
BOOL
Activation of the "Write parameters" function
FALSETRUE Transmitting a parameter write request
FALSE Outputs are reset
• If the execution of the FB has not been completed yet:
• Outputs are reset after request has been completed
• Status signals are at least set for one cycle.
wIndex
WORD
Index of the parameter to be written
bySubIndex
BYTE
Subindex of the parameter to be written
xUseIndexAsParam
BOOL
FALSE Selection indices according to CANopen
TRUE Selection indices according to Lenze parameters.
• The value given at wIndex is interpreted as parameter/code
number.
dwData
DWORD
Parameter value to be written
byNrOfByte
BYTE
Number of the bytes to be written
