Option description and instructions 33
FSE module
When a safety function is active, the fault reaction function of the FSO module trips the
drive if it detects a failure in the FSE module. The FSO module activates the STO function.
This activates the drive STO function. The drive STO function is active until the fault has
been repaired.
When there are no active safety functions, the fault reaction function depends on the value
of FSO parameter
FSE diagnostic failure reaction
(see section
on page
The FSO module goes into the Fail-safe mode. The FSO module LED STATUS/FAULT is
red and the FSE module LED STATUS is off until the fault has been repaired. Also the
drive indicates some of the FSE module faults.
To exit the Fail-safe mode, remove the cause of the fault and reset the FSO module by
switching the power off and on, by pressing the
Boot FSO
button on the
Safety view
of
Drive composer pro or with drive parameter
96.09 FSO reboot
.
For more information, see the drive firmware manual,
FSO-21 safety functions module
user’s manual
(3AXD50000015614 [English]) and
FSE-31 pulse encoder interface module
user’s manual
(3AXD50000016597 [English]).
Safety encoder
The FSE module indicates the internal faults of the safety encoder as cabling faults. This
activates the fault reaction function in the FSE module. This causes the FSO module to go
into the Fail-safe mode (see previous sections).
The FSO module LED STATUS/FAULT is red and the FSE module LED ENC STATUS is
off until the fault has been repaired. Also the drive indicates the safety encoder fault.
The FSO module LED STATUS/FAULT is red and the FSE module LED ENC STATUS is
off until the fault has been repaired. Also the drive indicates the safety encoder fault.
To exit the Fail-safe mode, remove the cause of the fault and reset the FSO module by
switching the power off and on, by pressing the
Boot FSO
button on the
Safety view
of
Drive composer pro or with drive parameter
96.09 FSO reboot
.
The safety encoder goes into the Safe state. To exit the Safe state, remove the cause of
the fault and reboot the safety encoder (for example, by switching the power off and on).

(3AXD50000016597 [English]).
STO function in the drive
The STO function in the drive has internal fault diagnostics and a fault reaction function
which causes a fault trip in case it detects a redundancy fault of STO control signals or any
internal failure. See the hardware and firmware manuals of the drive.
