The Safe torque off function 207WARNING! The Safe torque off function does not disconnect the voltage of themain and auxiliary circuits from the drive. Therefore maintenance work onelectrical parts of the drive or the motor can only be carried out after isolating thedrive from the main supply.WARNING! The Safe torque off functionality is only achieved through the XSTOconnector of the motor-side converter control unit. True Safe torque offfunctionality is not achieved through the XSTO connectors of the line-sideconverter control unit.The Safe torque off function is supported by any ACS880 motor-side converter firmware. Itis not supported by line-side converter firmware.WARNING! (With permanent magnet or synchronous reluctance [SynRM] motorsonly) In case of a multiple IGBT power semiconductor failure, the drive systemcan produce an alignment torque which maximally rotates the motor shaft by180/p (with permanent magnet motors) or 180/2p (with synchronous reluctance [SynRM]motors) degrees regardless of the activation of the Safe torque off function. p denotes thenumber of pole pairs.Notes:• If a running drive is stopped by using the Safe torque off function, the drive will cut offthe motor supply voltage and the motor will coast to a stop. If this causes danger or isnot otherwise acceptable, stop the drive and machinery using the appropriate stopmode before activating the Safe torque off function.• The Safe torque off function overrides all other functions of the drive.• The Safe torque off function is ineffective against deliberate sabotage or misuse.• The Safe torque off function has been designed to reduce the recognized hazardousconditions. In spite of this, it is not always possible to eliminate all potential hazards.The assembler of the machine must inform the final user about the residual risks.MaintenanceAfter the operation of the circuit is validated at start-up, the STO function shall bemaintained by periodic proof testing. In high demand mode of operation, the maximumproof test interval is 20 years. In low demand mode of operation, the maximum proof testinterval is 5 or 2 years; see section Safety data (page 208). It is assumed that alldangerous failures of the STO circuit are detected by the proof test. To perform the prooftest, do the Acceptance test procedure (page 205).Note: See also the Recommendation of Use CNB/M/11.050 (published by the Europeanco-ordination of Notified Bodies) concerning dual-channel safety-related systems withelectromechanical outputs:• When the safety integrity requirement for the safety function is SIL 3 or PL e (cat. 3 or4), the proof test for the function must be performed at least every month.• When the safety integrity requirement for the safety function is SIL 2 (HFT = 1) or PL d(cat. 3), the proof test for the function must be performed at least every 12 months.The STO function of the drive does not contain any electromechanical components.In addition to proof testing, it is a good practice to check the operation of the function whenother maintenance procedures are carried out on the machinery.
