Implementing the Prevention of unexpected start-upfunction￭ Cabinet-installed multidrivesYou can order the drive with a Prevention of unexpected start-up (POUS) function. ThePOUS function enables short-time maintenance work (like cleaning) on the non-electricalparts of the machinery without switching off and disconnecting the drive. See the appropriateuser’s manual for the wiring, start-up and operation instructions.Manual code (Eng-lish)User’s manualOption code3AUA0000145922Prevention of unexpected start-up, with FSO-xx safety functionsmodule+Q9503AUA0000119894Prevention of unexpected start-up, with safety relay+Q957￭ Multidrive modulesPOUS is not available as an option from ABB.Implementing the Safely-limited speed function￭ Cabinet-installed multidrivesYou can order the drive with Safely-limited speed function (option +Q966). It enables theuser to safely operate close to the machine at low speed, without stopping it.For the wiring, start-up and operation instructions, see Safely-limited speed user’s manual.￭ Multidrive modulesSafely-limited speed function is not available as an option from ABB. However, the cabinetbuilder can implement it with an optional safety module available from ABB. See Implementingthe functions provided by the FSO-xx safety functions module (page 36).Implementing the functions provided by the FSO-xx safetyfunctions module￭ Cabinet-installed multidrivesYou can order the drive with an FSO-xx safety functions module (option +Q972 or +Q973)which enables the implementation of functions such as Safe brake control (SBC), Safe stop1 (SS1), Safe stop emergency (SSE), Safely limited speed (SLS) and Safe maximum speed(SMS).The settings of the FSO-xx are at default when delivered from the factory. The wiring of theexternal safety circuit and configuration of the FSO-xx module are the responsibility of themachine builder.The FSO-xx reserves the standard Safe torque off (STO) connection of the inverter controlunit. STO can still be utilized by other safety circuits through the FSO-xx.For wiring instructions, safety data and more information on the functions provided by theFSO-xx, refer to its manual.36 Electrical planning guidelines
