Parameters 443
SAFEIO.21 Safety relay 1 output Sets the digital output connected to the
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 to the same
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
SAFEIO.22
Safety relay 1 feedback ).
None
None No output connected
DO X113:7 & X114:7 Redundant output X113:7 & X114:7
DO X113:8 & X114:8 Redundant output X113:8 & X114:8
DO X113:9 & X114:9 Redundant output X113:9 & X114:9
SAFEIO.22 Safety relay 1
feedback
Sets the digital feedback input of safety
relay 1.
Parameter
SAFEIO.23 Safety relay 1
feedback type sets the type of the feedback
input.
None
None No input connected
DI X113:1 Single input X113:1
DI X113:2 Single input X113:2
DI X113:3 Single input X113:3
DI X113:4 Single input X113:4
DI X114:1 Single input X114:1
DI X114:2 Single input X114:2
DI X114:3 Single input X114:3
DI X114:4 Single input X114:4
SAFEIO.23 Safety relay 1
feedback type
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.
Mechanicall
y linked NC
contacts
Mechanically linked
NC contacts
Feedback of the safety relay is NC (inverted
state compared with the relay).
Mechanically linked
NO contacts
Feedback of the safety relay is NO (same
state compared with the relay).
