If a fault occurs when the start inhibit is activated, then this fault must be
removed, before the protective devices of the machine or system are moved
aside (i.e. personnel enter the hazardous zone). After the fault has been
removed, the start inhibit sequence must be repeated to ensure it is functio-
ning correctly.
Setting–up operation may only be executed by qualified specialist personnel
with the safety devices, provided by the machine manufacturer, activated.
This mode may only be able to be selected via a mode selector switch
which can be locked and it must only be possible to access the machining
area using a safety switch, as in this mode, the protective devices are disa-
bled and also the start inhibit functions of the drives are de–activated. Other-
wise, all of the drives of the machine and system must, in this case, be auto-
matically isolated from the supply. For hanging axis, it should be ensured
that the drive drives are reliably held so that no energy can be fed back into
the DC link.
The relevant regulations for setting–operation must be taken into account.
The protective devices for the restricted hazardous zone of the drive can
now be moved aside (i.e. personnel can enter the hazardous zone).
If one of the following faults occurs with the protective devices disabled,
then EMERGENCY OFF must always be immediately initiated.
In this case, all drives of the machine and system are isolated from the
supply through the line contactor.
The acknowledge contact remains open and the start inhibit is not activated:
– there is a fault in the external control circuit itself.
– there is a fault in the signal lines of the acknowledge contact.
If all previous steps have been correctly executed, all of the drives in the restric-
ted working zone are locked–out to prevent drives starting accidentally, and
personnel can enter or access the restricted hazardous zone.
