Functions (Logic 5)
●Safety inputs: X0 to X13 (T0 to T13)
X0 to X13 (T0 to T13) function as dual channel dependent inputs.
The combinations of dual channel inputs are shown below. Incorrect use of these combinations
will result in an error. The input monitor error detection time between dual channel inputs is
infinite.
For operation of only 1 contact of a dual channel dependent input, the behavior of SafetyOne is,
-ON→OFF→ON: Input monitor error is detected, and the state changes to the Protection state.
-OFF→ON→OFF: The state changes to the Protection state temporarily, after that, the state is
restored to Run state immediately.
(In these cases, the input monitor error detection time is 0.1s.)
For information about connected control devices, see “SAFETY PRECAUTIONS”.
X0-T0, X1-T1: Safety input 1 (If 1 or both contacts are OFF, the safety input is OFF.)
X2-T2, X3-T3: Safety input 2 (If 1 or both contacts are OFF, the safety input is OFF.)
X4-T4, X5-T5: Safety input 3 (If 1 or both contacts are OFF, the safety input is OFF.)
X6-T6, X7-T7: Safety input 4 (If 1 or both contacts are OFF, the safety input is OFF.)
X10-T10, X11-T11: Safety input 5 (If 1 or both contacts are OFF, the safety input is OFF.)
X12-T12, X13-T13: Safety input 6 (If 1 or both contacts are OFF, the safety input is OFF.)
Warning
Safety check signals (pulses signals) are sent from the drive terminals (T0 to T13) to diagnose the
connected safety devices and the input circuits. Safety check signals can not be used as power
for the connected devices.
Note: Solid state outputs, such as safety light curtains, can not be connected.
Note: If there are unused safety inputs, short between the receive terminals (Xn) corresponding to
the unused safety inputs and the drive terminals (Tn). If they are not shorted, the SafetyOne will
not turn ON the safety outputs.
●External device monitor inputs: X14 and X15 (T14 and T15)
X14 and X15 (T14 and T15) function as external device monitoring inputs.
X14 and T14 are used as contact monitoring for external devices connected to Y0 and Y1.
X15 and T15 are used as contact monitoring for external devices connected to Y2 and Y3.
Warning
Safety check signals (pulses signals) are sent from the drive terminals (T14, T15) to diagnose the
external devices and the monitor circuits. The safety check signal can not be used as a power for
connected devices.
Note: If there are unused safety outputs, short between the external device monitor terminals (Xn)
corresponding to the unused safety outputs and the drive terminals (Tn). If they are not shorted,
the SafetyOne detects an input monitor error. As the result, the error LED displays “1” and the
state changes to the Protection state.
