Function Safety Ss1: Sequence Output Signal (Reference Value 89); Function Safety Sls: Sequence Output Signal (Reference Value 90) - Fuji Electric Alpha7 VV User Manual

Function safety SS1: Sequence output signal (Reference value 89)

This signal turns on while the safe stop 1 (SS1) function is running.
This signal is valid only when using the SS1 function.
* The SS1 function is a function contained in safety module (WSU-ST1) function.
 Function
The signal turns on while the function is running when the input terminal to which the SS1 function
is assigned turns off (open circuit).
The signal turns off while the function is not running when the input terminal to which the SS1
function is assigned turns on (short circuit).
However, if used with restart function enabled, the signal turns off when operation is resumed
after a restart signal has been input.
 Parameter setting
To assign function safety SS1 to a sequence output terminal, specify the value (89) corresponding
to the output terminal function setting parameter.
 Relevant description
Refer to the User's Manual of function safety module (WSU-ST1) for details on the SS1 function.

Function safety SLS: Sequence output signal (Reference value 90)

This signal turns on while the Safe-Limited Speed (SLS) function is running.
This signal is valid only when using the SLS function.
* The SLS function is a function contained in function safety module (WSU-ST1).
 Function
The signal turns on while the function is running when the input terminal to which the SLS function
is assigned turns off (open circuit).
The signal turns off while the function is not running when the input terminal to which the SLS
function is assigned turns on (short circuit).
However, if used with restart function enabled, the signal turns off when operation is resumed
after a restart signal has been input.
 Parameter setting
To assign function safety SLS to a sequence output terminal, specify the value ("90")
corresponding to the output terminal function setting parameter.
 Relevant description
Refer to the User's Manual of function safety module (WSU-ST1) for details on the SLS function.
