General guidelines
•
For planning the FSE-31 wiring, see chapter Planning for
installation in the FSO-21 safety functions module user’s
manual (3AXD50000015614 [English]).
•
Route the encoder cables separately from power cables (drive,
motor, etc).
•
Do not install more than one FSE-31 module to a drive.
•
Use the same power supply for the FSE-31 module and the
FSO-21 module. If there is no power, or if the power is not
sufficient, FSE-31 remains in Safe state. If this occurs when
FSO is in running mode, FSO will go into fail-safe mode.
•
The safety encoder must be attached to the motor shaft
according to the instructions of the encoder manufacturer.
FSE-31 does not detect mechanical failures outside of the
encoder (for example, motor shaft slipping).
•
If an internal safety encoder failure occurs, the safety encoder
goes into Safe state. To recover from these situations, you
must reboot the FSE-31 module by switching the power off and
on.
