APPLICATIONS THAT DO NOT REQUIRE STO FUNCTION
Here the STO inputs X10/01 and X10/03 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 X10/02 or X10/4 must be earthed, i.e. they should not both be earthed otherwise it is possible to create an earth loop.
STO inputs X10/01 and X10/03 must be
connected to 24VDC with respect to
terminals X10/02 or X10/04.
STO Status output on X10/05 and X10/06
may be left disconnected.
All wiring shown is within the control cubicle.
