Number of
faults
2089
Number of faults that have occurred since
the last clearing of the fault buffer (or
since the last activation of the axle).
Setting to 0 clears the error list, other
values are not permitted.

R/W
*) In case the EtherCAT interface is switched on continuously, the fault buffer might be filled
with one or more values after switching off and on again the motor power supply. This neither
influences the processing of the flow chart (see section “Flow chart”) nor the actual values
of the status bits.
However, after switching on the motor power supply again, the fault buffer might be flushed
in the following way as needed:
If the only error code which is contained is error code 0x8603, a simple flushing of the fault
buffer is sufficient (setting SDO #2089 to 0). However, if additional error codes are listed,
rather a reset of all connected drives has to be carried out. This takes place by setting SDO
#200D to -3. Alternatively, the reset might also be executed by a positioning run, e.g. to the
actual position. After this run has been finished, the fault buffer also might be flushed by
setting SDO #2089 to 0.
