Implementing the Safe torque off function
See chapter The Safe torque off function (page 183) .
Implementing the Prevention of unexpected start-up
function
You can order the drive with a Prevention of unexpected start-up (POUS) function. The
POUS function enables short-time maintenance work (like cleaning) on the non-electrical
parts of the machinery without switching off and disconnecting the drive.
See the appropriate manual for more information.
TO BE ADDED
Implementing the functions provided by the FSO-xx safety
functions module
You can order the drive with an FSO-12 or FSO-21 safety functions module (Q972
or +Q973) which enables the implementation of functions such as Safe brake control (SBC),
Safe stop 1 (SS1), Safe stop emergency (SSE), Safely limited speed (SLS) and Safe
maximum speed (SMS).
The settings of the FSO-xx module are at default when delivered from the factory. The wiring
of the external safety circuit and configuration of the FSO-xx module are the responsibility
of the user.
The FSO-xx module reserves the standard Safe torque off (STO) connection of the inverter
control unit. STO can still be utilized by other safety circuits through the FSO-xx.
See the appropriate manual for more information.

Implementing the Power-loss ride-through function
Implement the power-loss ride-through function as follows:
• Check that the power-loss ride-through function of the drive (inverter unit) is enabled.
See the drive firmware manual.
• Make sure that the control of the main contactor/breaker either keeps the contactor
closed over the short power break, or closes it after the break automatically.
