Functional description

In case of use of the STO function the input STO-Enable must be connected to the exit of
a security control or a safety relay, which meets at least to therequirements of the SIL
CL2 according to IEC 62061 and PL d according to ISO 13849-1 (see the connection dia-
gram on page 42).
Possible states of the servo amplifier in connection with STO function:
STO-ENABLE ENABLE
Because restart lock is a single-channel system, erroneous engaging will not be recog-
nized. Therefore the output of the control must be supervised for possible malfunction.
When wiring the STO input within one enclosure it must be paid attention to the fact that
the used cables and the enclosure meet the requirements of IEC 60204-1.
If the wiring leads outside the demanded enclosure, the cables must be laid durably
(firmly), and protected from outside damage (see chapter 6.9.7).
If the STO function is not needed in the application, then the input STO-ENABLE must be
connected directly with +24VDC. The STO function is passed by now and cannot be
used. The servo amplifier cannot be used as a safety component referring to the EC
Machine Directive now.
