DP-V1 Read response
The slave returns the code of the latest acknowledged fault
(2300h). The fault codes are according to the DRIVECOM
standard. See also the User’s Manual of the drive for drive specific
fault codes.
The implementation of the PROFIdrive profile in the RPBA-01
supports the storage of the active and the five latest occurred
different faults in the fault buffer. The fault codes can be accessed
by PROFIdrive parameters 945, 947 and 948 (see Table 22 on
page 101). The value zero indicates no fault. The subindexes of
these parameters are related to each other, i.e. parameter 945
with subindex 1 relates to subindex of parameter 947 and 948.
Example 4: Configuring the process data written to the drive
PROFIBUS parameter No. 915 (393h) can be used to define
which data is written cyclically to a drive parameter as application-
specific process data.
In the example below, the value of drive parameter 12.06 (4B6h) is
selected to be taken from PZD3. The parameter will continue to be
updated with the contents of PZD3 in each Request frame until a
different selection is made.
Subindex (IND) defines which process data word the required
data is taken from. Parameter Value selects the drive parameter to
which that word is mapped.
