Functions (Logic 11C)
●Safety inputs: X0 to X13 (T4 to T13)
Safety inputs are used to diagnose the status of connected safety devices, such as emergency stop
switches, and interlock switches.
Intended inputs
(Terminal names) Function
Function name Dual channel safety input
Symbol
Dual Channel Safety
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 (0.1s). The function
does not use drive terminals (T0 to T3).
Safety input 1
(X0, X1)
Safety input 2
(X2, X3)
Detail information Logic functions (5-317)
Intended inputs

Function name Dual channel direct opening input
Symbol
Dual Channel
Direct Opening
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).
Safety input 3
(X4-T4, X5-T5)
Safety input 4
(X6-T6, X7-T7)
Safety input 5
(X10-T10, X11-T11)
Safety input 6
(X12-T12, X13-T13)
Detail information Logic functions (5-311)
Warning
For connected control devices, refer to “SAFETY PRECAUTIONS”.
Safety check signals (pulses signals) are sent from the drive terminals (T4 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. If there are unused safety inputs in safety input 1 and safety input 2, connect the unused receive
terminals (Xn) to a 24V DC power supply (V+). If they are not connected, the SafetyOne does
not turn ON the safety outputs.
Note. Solid state outputs, such as safety light curtains, can not be connected to safety input 3 to safety
input 6.
Note. Use safety input 3 through safety input 6 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 in safety input 3 through safety input 6, connect the unused
receive terminals (Xn) to the corresponding drive terminals (Tn). If they are not connected, the
SafetyOne does not turn ON the safety outputs.
