Implementing The Safe Torque Off Function; Implementing Prevention Of Unexpected Start-Up Function (Option +Q957); Implementing Atex-Certified Safe Disconnection Function (Option +Q971); Implementing The Functions Provided With The Safety Functions Module Fso-11 - ABB ACS880-07 Hardware Manual

80 Guidelines for planning the electrical installation
Note: Pressing the stop key
switch of the drive from position "1" to "0" does not generate an emergency stop of the
motor or separate the drive from dangerous potential.
See the appropriate emergency stop user's manual for the wiring, start-up and operation
instructions.

Implementing the Safe torque off function

See chapter Safe torque off function
Implementing Prevention of unexpected start-up function
(option +Q957)
The drive provides Prevention of unexpected start-up function with safety relay (option
+Q957). See the Prevention of unexpected start-up (+Q957) user's manual for ACS880-07
(45...250 kW, 60...300 hp) drives (3AUA0000119910 [English]).
Implementing ATEX-certified Safe disconnection function
(option +Q971)
When the drive is equipped with the option +Q971, its Safe torque off function is certified
for use as a Safe disconnection function to protect equipment in potentially explosive
atmospheres according to European Council Directive 94/9/EC. For installation
instructions, parameter settings and technical data, see ATEX-certified Safe disconnection
function for ACS880 drives application guide (3AUA0000132231 [English]).
Implementing the functions provided with the safety
functions module FSO-11 (option +Q973)
The drive can be equipped with an FSO-11 safety functions module (option +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-11 are at default when delivered from the factory. The connectors
of the module are pre-wired to a terminal block, see the circuit diagrams. The wiring of the
external safety circuit and configuration of the FSO-11 module are the responsibility of the
machine builder.
The FSO-11 reserves the standard Safe torque off (STO) connection of the drive control
unit. STO can still be utilized by other safety circuits through the FSO-11.
