Safe torque off function 205MaintenanceAfter 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, themaximum proof test interval is 20 years. In low demand mode of operation, themaximum proof test interval is 2 years. The test procedure is given in sectionAcceptance test procedure (page 203).In addition to proof testing, it is a good practice to check the operation of the functionwhen other maintenance procedures are carried out on the machinery.Include the Safe torque off operation test described above in the routine maintenanceprogram of the machinery that the drive runs.If any wiring or component change is needed after start up, or the parameters arerestored, follow the test given in section Acceptance test procedure (page 203).Use only spare parts approved by the manufacturer.Fault tracingThe indications given during the normal operation of the Safe torque off function areselected by parameter 31.22 STO indication run/stop.The diagnostics of the Safe torque off function cross-compare the status of the twoSTO channels. In case the channels are not in the same state, a fault reactionfunction is performed and the drive trips on an “STO hardware failure” fault. Anattempt to use the STO in a non-redundant manner, for example activating only onechannel, will trigger the same reaction.See the drive firmware manual for the indications generated by the drive, and fordetails on directing fault and warning indications to an output on the control board forexternal diagnostics.Any failures of the Safe torque off function must be reported to the manufacturer.
