140 Safe torque off function
The function also corresponds to Prevention of unexpected start-up as specified by EN
ISO 14118:2018 (ISO 14118:2017) and Uncontrolled stop (stop category 0) as specified in
EN/IEC 60204-1.
 Compliance with the European Machinery Directive
See section Compliance with the European Machinery Directive on page 124. See
Electrical planning instructions for ACS880 multidrive cabinets and modules
(3AUA0000102324 [English]).
Wiring
The following diagrams present examples of Safe torque off wiring for
• a single drive (page 141)
• multiple drives (page 145)
• multiple drives when an external 24 V DC power supply is used (page 146).
For information on the specifications of the STO input, see section Default I/O connection
diagram (ABB standard macro) on page 84.
For drives with option +L537
, see CPTC-02 ATEX-certified thermistor protection module,
