Fault tracing 505
• Reboot the FSO with drive parameter 96.09 FSO reboot (Drive composer or
control panel).
• Note: The FSO accepts a 'soft boot' if it is in Fail-safe mode and the motor is
stopped.
If necessary, also reset the fault in the drive using the control panel (by pressing the
Reset button) or the Drive composer pro PC tool, or through the fieldbus.
Note: When using FSO with an FSE and a safety encoder: if an internal safety
encoder failure occurs, the safety encoder goes into a safe state. To recover from
these situations, you may have to reboot the safety encoder (for example, by
switching the power off and on).
If FSO is not recovering from the fault, contact your local ABB representative.
Internal fault
If there is an internal fault in FSO or FSE module that leads to a permanent defect,
the module must be replaced. The FSO and FSE modules are not repairable.
Reporting problems and failures
If you detect a failure in the safety module or safety function that prevents FSO fault
recovery, contact your local ABB representative. Provide the support package file of
your configuration and the safety file of the FSO module. For more information, see
Drive composer pro PC tool manual.
