4.2.2.3 Set-addressing with subindex from software V2.3

Bit 8 of parameter FBS Config was divided from software V2.3. Bit 12 is additionally defined in
parameter FBS Config. Thereby it is possible to make the coding of the subindex for the acyclic
parameter access (via CoE -> SDO) independent from the coding of the subindex in the values
of the process data mappings. Further information can be taken from the description of the FBS
Config parameter.

4.2.3 Process data communcation

Non-addressed setpoints can be preset via the process data channel to the KEB F5 and actual
values can be requested. Data communication of the process data between application and Eth-
erCAT slave controller occurs via 3-buffer mechanism. The maximum of process data that can be
transferred is 8 byte each per direction.

4.2.4 Distributed clocks

The function of the distributed clocks is used for the synchronous operating mode (4.3.3) in the
KEB-F5-EtherCAT operator. In this mode the interrupt cycles of the FI control is synchronized to
the EtherCAT distributed clock-cycles. Therefore a high-precision synchronisation of several KEB-
F5 inverters is possible. If the distributed clocks are not supported or activated by the EtherCAT
master, the KEB F5 EtherCAT operator is working completely asynchronous to the EtherCAT cycle.

4.3 Functions

4.3.1 Process data mapping

Which parameters of the inverter control concern to the process data is determined by the process
data assignment. The default process data assignment for this is:
Process output data (EtherCAT master => KEB slave):
Byte0
Sy.43: control word (long)
LSByte
Process input data (KEB-Slave => EtherCAT-Master):
Byte0
Sy.44: status word (long)
LSByte
Maximally 16 byte process data per data direction are supported from software version
V2.3. The 'ExtendedPDMode' must be activated for this function.
