DB Control

Enables quick motor control during servo operation by turning off SVONEN terminal and
forming DB control circuit while the gating motion is turned off when the motor stops. However,
if the DB control status is continuously maintained while the motor remains stopped, it is not
easy to achieve free-run of the motor in case the user so desires. This menu therefore helps the
user to achieve free-run of the motor by turning off the SVONEN terminal to create DB control
circuit when controlling the motor and by opening the DB control circuit when the motor comes
to a stop.
0: The DB control circuit is activated only during motor control by turning off the SVONEN
terminal of the motor, and free-run is activated only below 100[rpm] after the motor stops.
1: DB control always operates even when the motor servo is turned off.
