Description
safety relay 1.
To connect the safety relay to a certain
safety function, you must set the same
digital outputs in the output parameter for
that safety function. For example, if you set
parameter
SBC.21 SBC output
value as you set for the safety relay output,
the safety relay is active when the SBC
function is active.
Note: The output must always be redundant.
Otherwise the feedback signal of the safety
relay is not used (see parameter
Safety relay 1
feedback).
No output connected
Sets the digital feedback input of safety
relay 1.

Sets the type of the feedback signal for
safety relay 1.
Note: FSO reads the feedback signal in
every state change situation, ie, when STO
is activated. The feedback delay is 800 ms
for both feedback types, that is, a feedback
signal from the safety relay must be received
within 800 ms.
Feedback of the safety relay is NC (inverted
state compared with the relay).
Feedback of the safety relay is NO (same
state compared with the relay).
