Description of operation This function is a safety output to output safety
information processed by SafetyOne. The
output is turned OFF after the preset time of the
OFF-delay timer (OFF-delay output).
Safety output 1
(Y0, Y1)
Safety output 2
(Y2, Y3)
Detail information Logic functions (5-335)
Note. When the SafetyOne changes to Protection state due to input monitor error, all safety outputs
(safety output 1 and safety output 2) are turned OFF after the preset OFF-delay time.
Note. When the SafetyOne changes to Stop state due to circuit failure or other errors, all safety
outputs (safety output 1 and safety output 2) are turned OFF, immediately.
Note. Set time of safety output with timer is active independent of the selected mode.
●Safety input monitor outputs: Y4 to Y11
Safety input monitor outputs are used to output the status of safety inputs in SafetyOne.
Intended outputs
(Terminal names) Target safety inputs
(Terminal names) Description of operation
Safety input 1 monitor output
(Y4) Safety input 1
(X0-T0: TEACH) When TEACH mode (X0) is selected,
the monitor output is ON. When
TEACH mode is not selected, the
monitor output is OFF.
Safety input 2 monitor output
(Y5) Safety input 2
(X2-T2, X3-T3)
Safety input 3 monitor output
(Y6) Safety input 3
(X4-T4, X5-T5)
Safety input 4 monitor output
(Y7) Safety input 4
(X6-T6, X7-T7)
Safety input 5 monitor output
(Y10) Safety input 5
(X10, X11)
Safety input 6 monitor output
(Y11) Safety input 6
(X12-T12, T13-X13)
When the target safety input is ON,
the monitor output is ON. When the
target safety input is OFF, the monitor
output is OFF.
Note. When the targeted safety input detects an input monitor error, input circuit failure or EMC the
disturbance, corresponding safety input monitor output becomes a pulse output (1Hz). The
monitor output is OFF in other errors, Initial state, or Configuration state.
