When multiple signals are allocated to the same terminal,the signals are handled with OR logic, which affects the ON/OFF state of the other signals. Refer to 7.3.2 Input Circuit SignalAllocation.TypeSignalNameConnector PinNumberSettingMeaningOutput /CLT Must be allocated ON (low level) Servomotor output torque is being limited.OFF (high level) Torque is not being limited.The output terminal must be allocated with parameter Pn50F to use this output signal.
