3.3 I/O Signal Allocations3-213 Wiring and Connection3.3 I/O Signal AllocationsThis section describes the I/O signal allocations.3.3.1 Input Signal AllocationsInput signals are allocated as shown in the following table.Refer to the Interpreting the Input Signal Allocation Tables and change the allocations accordingly.• Inverting the polarity of the forward run prohibited and reverse run prohibited signalsfrom the factory setting will prevent the overtravel function from working in case of sig-nal line disconnections or other failures.If this setting is absolutely necessary, check the operation and confirm that there areno safety problems.• When two or more signals are allocated to the same input circuit, input signal level isvalid for all allocated signals, resulting in an unexpected machine operation.Input Signal Namesand ParametersValidityLevelInputSignalCN1 Pin NumbersConnection NotRequired(SERVOPACKjudges the connec-tion)13 7 8 9 10 11 12 AlwaysONAlwaysOFFForward Run ProhibitedPn50A.3H P-OT 0 1 2 3 4 5 6 7 8L /P-OT 9 A B C D E FLevel at which input signalallocations are valid.The parameter set values to be used are shown.Signals are allocated to CN1 pins according to theselected set values.Values in cells in bold lines are the factory settings.If always ON (7) or always OFF (8) is set, signalswill be processed in the SERVOPACK, which willeliminate the need for wiring changes.
