Applications that do not require STO function
Here the STO inputs X11/01 and X11/03 have been set to the inactive state (tied to +24V). Drive control is
performed solely through software with no inherent safety function. The drive is controlled with its own
start and stop pushbuttons.
Note: Only X11/02 or X11/4 must be earthed, i.e. they should not both be earthed otherwise it is possible to
create an earth loop.
STO inputs X11/01 and X11/03
must be connected to 24VDC with
respect to terminals X11/02 or
X11/04.
STO Status output on X11/05 and
X11/06 may be left disconnected.
All wiring shown is within the
control cubicle.
