GB - 19Safety Function STOCalculation of the jerk:Rotation angle of the jerk W R [°] = 180°–––––––––––––––––––––––––––––––––Pole-pair number p • gear reduction ratio gThis behaviour can occur either by a short circuit of the IGBTs or by interconnection (alsoshort circuit) of the control drivers. The error should be regarded as critical, if the drive re-mains in STO status.3.2 Classification of STO according IEC 61508PFH 2.6 • 10-12 1/hPFD 2.3 • 10-7 on demandProof-Test-Interval T 20 yearsFor SIL classification in connection with the applications consider the failure rates of the ex-ternal switch devices for final evaluation.3.3 Classification of STO according EN ISO 13849Category 4MTTFD >1000 yearsDC highFor the classification within a performance level in connection with the applications considerthe failure rates of the external switch devices for final evaluation.3.4 Additional instructions• The unit must be isolated from mains by main switch when working on parts under volt-age.• Mechanical brakes must be installed additionally if external forces have effect to the driveaxis, e.g. vertical axes (hanging loads) or rotary axes with asymmetrical weight distribu-tion.• For the protection against pollution (pollution degree 2) the installation of the units mustbe provided in environment with increased protection (e. g. control cabinet IP 54).• Make sure that no small parts fall into the COMBIVERT during assembly and wiring. Thisalso applies to mechanical components, which can lose small parts during operation.• Check the safety functions and error responses and generate an acceptance report afterinstallation.• The start-up can be prevented with interruption of the STO signals. STO may not bereleased in case of danger according to EN 60204-1. Also note the instructions to theexternal safety switch devices.• Dimension the safety application by way that the corresponding input current of the safetyfunctions is available for the inputs (see chapter 2.5.1).Selection ofsuitable volt-age sourcesUse for the connection only suitable voltage sources with safeisolation (SELV / PELV) in accordance with VDE 0100 with nom-inal voltage of 24 Vdc ± 10%. Pay attention on a sufficient over-voltage category of the voltage supply.
