4.2 Protection Sequence Design43■ DB OFF InputSequence Input Signal: The basic connection and handling method for the (DB OFF)signal is shown below. This is used to forcibly release the “DB stop state” during ServoOFF from the upper-level device.Switches the motor between a powered and a non-powered state.■ RUN Signal OutputPhotocoupler Output Signal: The basic connection method and handling method for the“RUN” signal is shown below. This output signal indicates that the base block on theoutput inverter is released, and power is being applied to the motor.→ Input DB OFF CN1-15 DB OFFWhenONCN1-15is “L” levelDB stop at Servo OFF DB ON DB Stop StateDB stop at Servo OFFWhenOFFCN1-15is “H” levelReleases the DB stop and goes tofree run at Servo OFF DB OFFDB Stop ReleaseRelease DB stopaccording to an inputsignalOutput → RUN CN1-7 RUN Signal OutputON State CN1–7, 10 is “closed”CN1–7 is level “L” Base BlockOFF State CN1–7, 10 is “open” CN1–7 is level “H” Base Block Released24V Power+24V +24VINAmplifierCN1-13 3.3kΩPhotocouplerUpper-LevelDevice DB-OFF CN1-15 5mA0VPhotocoupler Output perOutputMax.
