12 Option description and instructions
short-time operations (like cleaning) and/or maintenance work on the non-electrical parts
of the machinery without switching off and disconnecting the drive.
For a detailed description of the Safe torque off function, see the inverter unit hardware
manual
.
For more information on the FSO module, see FSO-12 safety functions module user’s
manual (3AXD50000015612 [English]) or FSO-21 safety functions module user’s manual
(3AXD50000015614 [English]).
For more information on the FSE module, see FSE-31 pulse encoder interface module
user’s manual (3AXD50000016597 [English]).
The design principles of the Q950 comply with EN ISO 13850.
The STO function complies with EN/IEC 61800-5-2. For a complete list of related

Summary of wirings and settings
The wirings and settings of the POUS function are:
•
The inverter units are equipped with the FSO safety functions modules (Q973
or +Q972). ABB installs the modules at the factory.
•
The user must wire a dual-channel POUS switch to the FSO module. See section
Wiring on page 16 .
•
The user can wire a POUS indication lamp to the FSO module (optional).
•
The digital input of the FSO module to which the POUS switch is connected, is
selected as the input for the POUS request. This is an FSO module parameter that
ABB sets at the factory. The user must check the setting at the start-up.
•
The digital output of the FSO module to which the POUS indication lamp is connected,
is selected as the output for the POUS completed signal. This is an FSO module
parameter that ABB sets at the factory. The user must check the setting at the start-up.
Additional wirings when safety pulse encoders are used:
•
The inverter units are equipped with the FSE-31 pulse encoder interface modules
(L521). ABB installs the modules at the factory.
•
The motors must be equipped with safety pulse encoders. The user installs the safety
pulse encoders and wires them to the FSE modules.
The user must make sure that
the required safety integrity (SIL/PL) can be achieved with the used safety encoder(s).

and Wiring on page 16 . For a detailed description of parameter settings, see chapter
Parameter settings on page 19 .
