This is one of three digital output terminals that provide a +24V dc output signal under certain conditions. They
allow for the connection of relays which, in conjunction with the Enable, Start/Run and Emergency Stop relay, can
be used to enhance the safe starting and stopping of the controller.
The drive is "healthy" (TRUE) if there is no Start command.
These are configurable outputs and can be used as required in the control system design, i.e. cubicle door lamps,
connection to a suitable PLC.
