■ DB OFF Input
Sequence 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 Servo
OFF from the upper-level device.
Switches the motor between a powered and a non-powered state.
■ RUN Signal Output
Photocoupler 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 the
output inverter is released, and power is being applied to the motor.
