Functions (Logic 11b)
●Safety inputs: X0 to X13 (T0 to T13)
Safety inputs are used to diagnose the status of connected safety devices, such as emergency stop
switches, interlock switches, and non-contact interlock switches.
Intended inputs
(Terminal names) Function
Function name Dual channel NO/NC input
Symbol
Dual
Channel
NO /NC
Description of operation This function diagnoses the status of
connected safety devices. This function
diagnoses the time interval of status
transition between each input of
duplicated inputs (0.5s).

Warning
For connected control devices, refer to “SAFETY PRECAUTIONS”.
Safety check signals (pulses signals) are sent from the drive terminals (T0 to T13) to diagnose
connected safety devices and input circuits. Safety check signals can not be used as a power supply
for connected devices.
Note. Solid state outputs, such as safety light curtains, can not be connected to safety inputs.
Note. Use safety inputs as specified combinations, such as receive terminal (Xn) and drive terminal
(Tn). If the combinations are incorrect, SafetyOne does not work correctly.
Note. If there are unused safety inputs, connect the unused receive terminals (Xn) to the
corresponding drive terminals (Tn) as shown in following table. If they are not connected
properly, the SafetyOne does not turn ON the safety outputs.
