(option +Q973) or the FSO-21 safety functions modules (option +Q972) to the inverter units. When safety pulse encoders are used, ABB installs the FSE- 31 pulse encoder interface modules (option +L521) and the FSO-21 modules to the inverter units.
In the supply and brake units, the XSTO input must not be used for any safety function purposes to ensure personnel safety. The Safe torque off function is supported by any ACS880 inverter or drive firmware. It is not supported by supply or brake firmware.
Introduction to the manual 9 Contents The chapters of this manual are briefly described below. Introduction to the manual (this chapter) introduces this manual and gives safety instructions. Option description and instructions describes the safety function and instructs how to wire and use it.
If you select EN/IEC 62061 or IEC 61511, make a safety plan. See EN/IEC 62061 or IEC 61511. Assess safety: analyze and evaluate risks (estimate SIL/PL) and define risk reduction strategies. Define the safety requirements. Design the safety system. The part of the design made by ABB is described in chapter Option description and instructions on page 11.
FSO-21 safety functions module (option +Q972) for the Prevention of unexpected start-up (POUS) safety function. ABB installs the FSO modules to the inverter units and sets default parameter values for the option at the factory. The user installs and wires an operating switch and an indication lamp (optional) on site.
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: •...

Option description and instructions 15 Initial status: The drive is in operation and the motor is not running Step Operation The user activates the POUS function by switching off the POUS switch [Sxx]. This activates the POUS function in the FSO module. The FSO module de-energizes the STO inputs on the inverter units control boards.
27, 28, 29, 30 There is a separate user interface (terminal block [X957]) inside the cabinet. ABB installs the FSO module and the wirings between the FSO modules and the inverter units at the factory. The FSO module has double terminals for the connection of the POUS switch.Wire the POUS switch to the appropriate terminals in the extension terminal block [X68].
Option description and instructions 17 When safety pulse encoders are used, ABB installs the FSO-21 and FSE-31 modules and the wirings between the FSO modules and the inverter units at the factory. The user must wire the safety pulse encoders to the FSE modules on site. Obey these rules: •...
18 Option description and instructions 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 inverter unit parameter 96.09 FSO reboot. For more information, see the inverter unit firmware manual and the FSO module user’s manual.
Parameter settings 19 Parameter settings Contents of this chapter This chapter lists the parameters that you have to set in the FSO modules and the inverter units. Introduction The person who configures the safety functions in the FSO module must be a competent person as required by IEC 61508-1 clause 6.
20 Parameter settings Follow the configuration steps described in the FSO module user’s manual, chapter Configuration. There are parameters that you must set always and parameters that are related only to certain safety functions. These tables list all the parameters that you must check and set for the option +Q950.
STO function. SAR0 parameters define the deceleration ramp (for more information, see the FSO module user’s manual). For the +Q950 option, ABB has set this parameter to value Immediate STO at the factory. Adjust the default value when necessary.
POUS.02 POUS acknowledgement). For the option +Q950, ABB has configured the POUS indication signal to this digital output at the factory. Make sure that this value corresponds to the actual wiring. See the circuit diagrams of the delivery.
For more information, see the firmware manual. Safety pulse encoder parameters The inverter unit parameter settings in ACS880 primary control program when you use a safety pulse encoder: • parameter 90.41 Motor feedback selection is set to value Encoder 1.
Start-up and acceptance test 25 Start-up and acceptance test Contents of this chapter This chapter describes the start-up and acceptance procedure of the safety function. Safety encoder interface When you use safety pulse encoders in the safety application, validate the safety encoder interface as described in FSO-21 safety functions module user’s manual (3AXD50000015614 [English]), chapter Verification and validation.
26 Start-up and acceptance test Start-up and acceptance test You need the Drive composer pro PC tool to perform the start-up and acceptance test. Initial status: Make sure that the drive is ready for use, that is, you have done the tasks of the drive start-up procedure.
Page 27
Start-up and acceptance test 27 Action Make sure that the motors stay at zero speed and the inverter units indicate POUS as defined in section POUS indications on page 17. Note that there can be several POUS groups in a multidrives system. Make sure that only the desired inverter units indicate POUS.
If you change any wiring or component after the start-up, replace the FSO or FSE module, modify FSO module parameters or restore parameters to their factory default values, you must: • Use only ABB approved spare parts. • Register the change to the change log for the safety circuit. •...
30 Maintenance Proof test interval After the operation of the safety function is validated at start-up, the safety function must be maintained by periodic proof testing. In high demand mode of operation, the maximum proof test interval is 20 years. In low demand mode of operation, the maximum proof test interval is 2 or 5 years (high or low demand as defined in IEC 61508, EN/IEC 62061 and EN ISO 13849-1).
Technical data 31 Technical data Contents of this chapter This chapter gives general rules, notes and definitions related to safety functions and lists the related standards and directives. Safety data Safety performance with different safety pulse encoders See FSE-31 pulse encoder interface module user’s manual (3AXD50000016597 [English]).
32 Technical data Safety data values Each multidrives delivery is unique. If included in the customer order, ABB calculates the safety data for each POUS circuit of the multidrives delivery, and delivers the data separately to the customer. For the safety data of the FSO-12 module, see FSO-12 safety functions module user’s manual (3AXD50000015612 [English]).
IEC 61508-1 clause 6. The test procedures and report must be documented and signed by this person. Ambient conditions For the environmental limits for the safety functions and the drive, refer to the hardware manual.
