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 (T12, T13).
Safety input 6
(X12, X13)
Detail information Logic functions (5-317)
Warning
For connected control devices, refer to “SAFETY PRECAUTIONS”.
Safety check signals (pulses signals) are sent from the drive terminals (T0, T2 to T11) 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 input 1 through
Safety input 5.
Note. Use safety input 1 through Safety input 5, as specified combinations, such as receive terminal
(Xn) and drive terminal (Tn). If the combinations are incorrect, SafetyOne does not work
correctly.
Note. When SafetyOne is in Run state or Protection state, input states are monitored in all safety
inputs. For example, if input monitor error is detected in safety input 2 although AUTO mode is
selected, SafetyOne detects error and transits to Protection state.
Note. If there are unused safety inputs in safety input 2 through safety input 5, 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.
Note. If safety input 6 is not used, connect the receive terminals (X12 and X13) to a 24V DC power
supply (V+). If they are not connected, the SafetyOne does not turn ON the safety outputs.
